Claim: Most of Earth's carbon may be hidden in the planet's inner core, new model suggests

From the University of Michigan, and the “department of models that can’t ever be verified”, comes this claim

F7.large[1]

ANN ARBOR–As much as two-thirds of Earth’s carbon may be hidden in the inner core, making it the planet’s largest carbon reservoir, according to a new model that even its backers acknowledge is “provocative and speculative.”

In a paper scheduled for online publication in the Proceedings of the National Academy of Sciences this week, University of Michigan researchers and their colleagues suggest that iron carbide, Fe7C3, provides a good match for the density and sound velocities of Earth’s inner core under the relevant conditions.

The model, if correct, could help resolve observations that have troubled researchers for decades, according to authors of the PNAS paper.

The first author is Bin Chen, who did much of the work at the University of Michigan before taking a faculty position at the University of Hawaii at Manoa. The principal investigator of the project, Jie Li, is an associate professor in U-M’s Department of Earth and Environmental Sciences.

“The model of a carbide inner core is compatible with existing cosmochemical, geochemical and petrological constraints, but this provocative and speculative hypothesis still requires further testing,” Li said. “Should it hold up to various tests, the model would imply that as much as two-thirds of the planet’s carbon is hidden in its center sphere, making it the largest reservoir of carbon on Earth.”

It is now widely accepted that Earth’s inner core consists of crystalline iron alloyed with a small amount of nickel and some lighter elements. However, seismic waves called S waves travel through the inner core at about half the speed expected for most iron-rich alloys under relevant pressures.

Some researchers have attributed the S-wave velocities to the presence of liquid, calling into question the solidity of the inner core. In recent years, the presence of various light elements–including sulfur, carbon, silicon, oxygen and hydrogen–has been proposed to account for the density deficit of Earth’s core.

Iron carbide has recently emerged as a leading candidate component of the inner core. In the PNAS paper, the researchers conclude that the presence of iron carbide could explain the anomalously slow S waves, thus eliminating the need to invoke partial melting.

“This model challenges the conventional view that the Earth is highly depleted in carbon, and therefore bears on our understanding of Earth’s accretion and early differentiation,” the PNAS authors wrote.

In their study, the researchers used a variety of experimental techniques to obtain sound velocities for iron carbide up to core pressures. In addition, they detected the anomalous effect of spin transition of iron on sound velocities.

They used diamond-anvil cell techniques in combination with a suite of advanced synchrotron methods including nuclear resonant inelastic X-ray scattering, synchrotron Mössbauser spectroscopy and X-ray emission spectroscopy.

It may be heavily tied up with models, but at least they ran experiments to validate what they were proposing by using empirical data. Validating a model goes a long way towards having it accepted.

forget it. it if you cant measure it directly you cant say anything about it. any time you use a model you are not doing science.
since we can’t see or touch the core we dont know. it could be empty or filled with green cheese.
models tell us nothing because they dont produce data.

Mosher, our criticism of climate models is valid because they are iterative models with finite precision of a system that is known to be nonlinear and chaotic.
Furthermore, they have failed for 18 years and counting, so it looks like our criticism has been vindicated.
Now, the climate scientists must scrap their models, come up with new ones, and make new predictions.

Dirk,
IMO work on models should go on the back burner until the climate system is better understood & computers more powerful. The models have been a tool to push an agenda, not to discover how nature works.
More data are needed & less modeling. As I’ve said before, the situation reminds me of the War on Cancer in the early ’70s. Massive amounts of money were wasted funding research before the science was ready. But at least then it was research & not GIGO modeling.

Mosher nonsense. I replied to this earlier. You make predictions based on a hypothesis these are tested by direct measurements or remote measurements (which BTW most large-scale physical science is validated) those are observations with known uncertainties. The physical model presented above is a good attempt (and used throughout the geological sciences dealing with extreme environments) but they are not observations. For example one could make predictions of observed S-wave propagation around the globe from tectonic events of differing magnitude based on the suggested hypothesis (or gravitational, geomagnitism). THAT IS HOW ALL EARTH STRUCTURAL MODELLING IS DONE!

I’m with Mosh on this, I’m going out on a limb and saying it simply isn’t green cheese, although green cheese is high in carbon, too. (sarc,etc.) Look modeling is done very successfully in engineering and science. We drill holes in an ore body and then use a statistical model to calculate ore reserves and grades and to optimize mining geometry, even the scheduling of loading and trucking either to the waste pile or the concentrator depending on grade and wind up with estimating a cost for doing this ~+/-15% – we’ve been at it a long time and we do end up with a mined out ore body and very accurate costs to compare to our estimates… er ah, model validation.
The difference with climate models is that they think they are doing the same thing. If your climate model isn’t within reasonable bounds of replicating observations, then your ‘experiments’ are not experiments with even simulated reality and the results can’t be called real data. With the geological model, we are careful to differentiate between data and model output – the data is from the drilling and other testing. In fact; in mining, it is against the law to not differentiate in this matter.
In thinking about important things that climate models haven’t been including, and musing on geological models and Willis’s thunderstorm cells, it occurred to me that everything in climate IS LOCAL, like the building blocks of ore of different grades integrated into a whole model of the ore body. I think the nonlinear chaotic systems view could be the barrier to good modeling. Trying to tie all these interlocking, interacting systems together in a model that one expects to project climate forward with is attempting the impossible. The solution of going to ever more powerful computers is just wasteful nonsense.
Maybe we should have separate models for the equatorial belt (20N/S?) over water and over land. This is really the earth’s central heating system/radiators. Take next the temperate zones either side with the main parameters acting there – largely horizontal circulatory system – air and water- mass and heat flow, etc. Then the polar areas north and south of 60 – these are a major part of the cooling system. Maybe separate models for summer and winter here. Separate models of natural variation to be added to the trends we get.
Have a separate model of frequency and effects of volcanic eruptions (also mainly equatorial effects) to modify the models, another for oceanic currents, other aerosols, etc. etc. Then see how we can put them together.
A simple example: if we want to model the firing of an artillery piece with muzzle velocity of V at an angle of 45 degrees, we can divide the motion into a constant horizontal component of Vcos45 for t seconds and the vertical component of (Vsin45t – 16t^2)*2 and determine how high the projectile goes, how far and how long it takes to land (assuming here level ground). We can add in atmospheric drag, wind vector and other things to get it closer to the real trajectory and time. Start with the simple. The system has limits – SSTs don’t go over 31, ice ages and interglacials seem to be capped as well, the overall temperature K varying a couple of percent.

Come on guys.
Take it back to Newton.
He came up with some mathematical models that work quite well to describe planetary bodies, ballistic motion, etc.
They are still useful today.
As further knowledge was gained in the area of space-time, the new mathematical models explained the inaccuracies in Newton’s equations.
Don’t throw the baby out with the bath water.
Just because folks in the climate science are clinging to ineffective models, doesn’t mean that models don’t have their place in science.
As knowledge is gained, it either affirms or disproves previous thought.

Interesting hypothesis, though considering the pressures involved I would favour the liquid hypothesis over this one.
That said, the dead dinosaur theory of crude oil is also being challenged by an inner earth hydro-carbon hypothesis at the moment, so best not to dismiss out of hand.

Given the pressures involved solid iron at high temperature remains eminently possible. There is considerable leeway for error given that we can only estimate the exact core composition and conditions but an article published in Nature circa 1999 seemed to show that it was at least possible based on lab testing of iron under pressure at high temperature.

As for the origins of oil the reality is that petroleum geologists use the presence of fossils of certain species as key markers of oil bearing rock. The fossils are typically those of plants, plankton and algae rather than major fauna. It may be that abiotic oil sources exist but most oil inproduction comes from fossil bearing strata.

The C13 signature of Hydrocarbons clearly shows an organic source. Someone just wants to make a name for themselves.

William:
Your comment is incorrect. There are dozens and dozens of observations and analysis results (including observations concerning the C12/C13 ratio) that supports the assertion that deep earth CH4 (core of earth) is the source for the deposits of natural gas and most of the petroleum oil on the planet.
There are multiple observations concerning the C13/C12 ratio that support the deep earth source for hydrocarbons. Plants of course preferentially use C12 in photo synthesis which explains why C13 is higher in the atmosphere. The C13/C12 ratio does not however increase with time in the sediment geological record which supports the assertion that there is a continuous deep carbon source of C12 (methane CH4) with low C13.
The anomalies concerning the C13/C12 ratio in petroleum and natural gas is one of the reasons why Thomas Gold and Russia/Ukraine geologists assert that the source of the earth’s hydrocarbons is from a deep earth source.
The Thomas Gold/Russia/Ukraine deep earth theory explains why: 70% of the planet is covered in water, provides the reason why there are massive concentration of hydrocarbon such as the 1.2 Trillion barrel heavy oil concentration in the Canadian province of Alberta (deep source of CH4 provides the pressure to push the CH4 through the mantel picking up heavy metals during the flowing process, the puzzle with the biological theory is why the massive concentration, what is source of the pressure and so on. Deep earth micro organisms eat the methane converting it to heavy oil and leaving biological residue), the reason why Saudi Arabia was 25% of the world’s oil and 50% of the Saudi Arabia oil is found in a single super, super, large oil field, explains why the solar wind has not stripped off water from the planet (i.e. CH4 is continually released from planet core which disassociates to form H2O and CO2), explains the composition of the atmosphere, explains why the atmosphere C12/C13 has remained constant with geological time (there is constant new source of high C12 from the core contained in CH4.)
There are two theories to explain how water and hydrocarbons came onto the earth: the late veneer theory and the deep CH4 theory. Roughly 100 million years after the earth was formed a Mars sized object struck the earth. That event formed the moon and stripped the mantel of light elements. There are two theories to explain why there are light elements on now on the earth’s surface. The late veneer theory hypothesis: Comets struck the early earth after the big splat event covering the very hot earth with hydrocarbons. The late veneer hypothesis requires that the earth had a Venus like atmosphere (atmospheric pressure of say 60 atmospheres) for the early earth, except with methane.
There are multiple problems with the later veneer hypothesis (See Thomas Gold’s Book Deep Hot Biosphere for details. One of the key problems is the observation that the percentage of heavy gaseous elements in the earth’s current atmosphere does not match that of comets (Comets are residues of the early solar systems. The comet elemental composition does match that of the sun). The late veneer theory’s explanation for the miss match of isotopes in the earth’s atmosphere to that of comets is that the early solar system had a close encounter with another solar system which temporary provided a limited source of comets to cover the earth but not significantly change the element composition of the sun.
The second hypothesis is the deep earth hydrocarbon theory. This theory hypothesizes that massive amounts of hydrocarbons (5% of the total core mass) are located in the earth’s core. As the core cools these hydrocarbon (CH4) are released. At very high pressures the CH4 forms longer chain molecules.
The release of CH4 is still occurring as the upper surface of the ocean is saturated with CH4 which indicates that CH4 is being released from some source.

I’ve seemed to have touched a nerve.
I’m not saying that is beyond the realms of reason that there are inorganic sources of methane in petroleum reservoirs, in fact there is without doubt huge volumes of organic compounds throughout our solar system that are clearly not biogenic.
All that being said there are many more lines of evidence for the biogenic origin of reservoir hydrocarbons than d13C values:-
– We only get significant reservoirs of simple organic molecules in particular geological settings: principally carbonate/sandstone formations above organic rich source rocks with particular burial histories.
– We can actually map and date hydrocarbon migration using mineral fluid inclusions. They come from organic rich source rocks – shales.
– gas chromatography of crude oil have many complex molecules that map directly to source rock chemistry (chemical fingerprinting).
– shale source rocks have “immature” hydrocarbons called kerogens with organic geochemistries that can only be explained by biological sources.
There are more but I wont bore you.

Another line of evidence for organic source for petroleum is the rotation of polarized light due to the “left-handed” symmetry of organic molecules. Petroleum exhibits this “left-handed” rotation of polarized light while synthetic oils do not.
But in fact, few scientists give serious consideration to any origin of petroleum other than organic.

The fact that biological processes show a preference for C12 does not mean that there are no non-biological processes that do the same. The statement that the C13 signature shows a biological origin (ie. the photosynthesis signature) is a claim based on only one process that we know of, nothing more.

mpainter, yes most oil (if not all, perhaps) is of biological origin. And abiotic oil hypothesis has no real world evidence and is of no practical use.
But I’ve never found the chirality argument to be persuasive. Oil is food for bugs. The effect of microbes on oil will add chirality to the mix. It seems improbable to me that oil in the ground is sterile.
The C13/C12 ratio is far more indicative – although I suppose a similar argument could be made there.
Hmm. I’ve just managed to disagree with both sides of the debate. It’s nice to be back in the crazy zone. As though I ever left.

M Courtney,
Do you posit microbes in a reservoir at, say, 200°F and 5,000 psi? Or do you posit microbes in the mantle?.
Or do say as Mosher that the core could be green cheese (and microbes)?
The rotation of polarized light by purified petroleum is a positive indication of its organic origin.

The Earth is not a tidy place. Crap moves. Lots of it. Expecting to find abiotic oil without life in it, or organic oil without some carbonate rock on hot iron synthesized oil in it, both are silly expectations. We know that hot minerals, like zeolites, in the presence of carbon sources and hydrogen sources (i.e. water) make hydrocarbons. We also know that life eats hydrocarbons and makes long chain fats. It’s all one big bowl of organic soup.
The “hard bit”, IMHO, is explaining why so much oil comes from near subduction zones without looking at abiotic processes on subducting carbonates; and explaining all the oil found on the bottoms of the oceans, and under 4 miles of rocks, and the liquid methane seeps from near volcanoes at the bottom of the ocean, and life forms eveolved to be dependent on oil seeps that had to exist for millions of years, and….
So why pollen? Because some of oil IS from algae sinking in ancient seas (such as North Sea oil). But why oil under miles of rock under the oceans? And why methane coming from volcanoes? And…. My answer is “some of each”. We just don’t know the ratios…

The theory of abiogenic hydrocarbon origins has been around forever despite have been disproven multiple ways. Hydrocarbon source rocks are all biogenic-marine shale kerogens or coal precursor peat. And Sweden drilled deep below an igneous cap rock where there ‘should have been abiogenic hydrocarbons’ found nothing. They are called fossil fuels for a reason. But are not dinosaur remains. You might find essay Much Ado about Nothing in Blowing Smoke: essays on energy and climate to be somewhat enlightening.

I don’t dispute biotic oil. But abiotic hydrocarbons clearly exist elsewhere where there is apparently no life; why not here?

It may not be able to be physically verified by taking samples (but technological surprises do happen). But the authors do admit that this is a speculative idea to solve a recognized question. Something is making the p waves move significantly slower than they should.
This paper is so unlike climate obsessed science: the issue is well defined. The evidence of a problem is significant ( half speed ). The authors are open: This is a speculation. And it is based on experiments (the diamond anvil).

That’s because it’s basic research. Basic research, by itself, rarely is “useful”. But basic research leads to applied research, and through applied research come useful products.
Bob Cringely wrote the best definition (http://www.cringely.com/2013/02/20/accidental-empires-chapter-5-role-models/):
“Basic research is something else—ostensibly the search for knowledge for its own sake. Basic research provides the scientific knowledge upon which R&D is later based. Sending telescopes into orbit or building superconducting supercolliders is basic research. There is no way, for example, that the $1.5 billion Hubble space telescope is going to lead directly to a new car or computer or method of solid waste disposal. That’s not what it’s for.
If a product ever results from basic research, it usually does so fifteen to twenty years down the road, following a later period of research and development.”
So you’re right: it’s interesting but not overly relevant to anything. But if they are onto something (see the other comments for stuff like abiotic oil), it’s going to be 2035 before we start to see the results.

I hesitate to speak for the moderators, but here is my take on the possible relevance of the article for WUWT. If carbon is not the main driver for global warming, then why not just pump and burn the oil as fast as we find it? Answer: because deep-Earth carbon is a finite non-renewable resource and we should leave some for the grandchildren. However if oil and gas come from the Earth’s core, it becomes a renewable resource and maybe the equation changes?
Of course it would not be as simple as that. I presume that even if oil and gas come from deep-Earth carbon, the rate of upward flow may be very slow indeed in which case it is once again a non-renewable resource.

Reply to  Michael D
December 2, 2014 2:59 pm

Even if oil were finite it would still be ethical to pump it as fast as needed. Future generations will have plenty of methane hydrates etc. Besides, why would future people have any more legitimate need than today’s poor?
The fact is that with advancing technology the oil may not even be needed in the future.

There’s certainly some carbon in the mantle at least. Diamonds form at depths of between 140km and 300km. Isotopes suggest the carbon is derived from both inorganic [original] and organic [brought down through subduction] sources.
It would be interesting to know if there are figures on how much carbon makes it from the ocean trenches down into the mantle [effectively carbon “sequestration”].
I wonder if it’s included in carbon cycle modelling ?

Stephen I have a bit of sympathy for your views. However, most benefits that come from physical science are due to trickle-down effects where small innovation and accumulation of knowledge lead to great breakthroughs – “standing on the shoulders of giants”.
even the detested climate models have led to improvements in how we approach computational problems. Other fields that directly affect you such as economics, finance, and ironically enough, petroleum engineering (to name but a few) will benefit from these in time.

Carbon originating for the earth’s core would seem to be one explanation for the shale gas and oil at such depths. Question, where would the hydrogen come from?

Let’s call a human lifetime 45 years, and the age of the earth 4.5 billion years (just to get to convenient powers of ten) – so the earth is about 100,000,000 human lifetimes. A trip from New York to Sydney is on the order of 10,000 km, or 10 Mm. So 1/100,000,000 of the trip from New York to Sydney is 0.1 m.

That depth is still well within the earth’s crust.
Continental crust is mostly 25 to 70 km thick, while the average oceanic crust is only around 7–10 km.
Assume just for the sake of argument an average deposition rate of merely a foot per millennium. That means the hydrocarbons found 20,000 feet down might be “only” 20 million years old. If they’re 200 million years old, then from the Triassic or Jurassic Period. That’s well after the coal-eponymous Carboniferous, separated by the Permian.
OTOH, can’t rule out hydrocarbons migrating upward from below the crust, either.

There are dozens and dozens of observations and analysis results that support the assertion that the source of petroleum oil and natural gas deposits on the planet is deep earth CH4. The most fundamental problem with the biogenic theory of oil formation is there is no viable natural physical process to convert plant residue to petroleum oil even for even very small amounts. The conversion of plant residue to petroleum oil hypothesis cannot explain the super, super, large petroleum oil deposits for multiple reasons.
What is the source of the biological material? There are massive deposits of light petroleum in sandstone and no nearby organic fossil residue. (This is the so called source problem that is not explained by the biogenic theory of oil formation.) There is no natural reaction in the conditions where the oil is found to convert plant residue to petroleum oil.
The deep earth hypothesis can explain why Saudi Arabia has 25% of the planet’s oil reserves half of which is contained in only eight fields. Half of Saudi Arabia production comes from a single field the Ghawar.
Excerpt from this wikipedia article on Oil Reserves
http://en.wikipedia.org/wiki/Oil_reserves

Saudi Arabia reports it has 262 gigabarrels of proven oil reserves (65 years of future production), around a quarter of proven, conventional world oil reserves. Although Saudi Arabia has around 80 oil and gas fields, more than half of its oil reserves are contained in only eight fields, and more than half its production comes from one field, the Ghawar field.

The following is an excerpt from Thomas Gold’s book the Deep Hot Biosphere which that outlines some of the observations which supports an abiogenic origin (non-biological, primeval origin), for petroleum and natural gas.

(1) Petroleum and methane are found frequently in geographic patterns of long lines or arcs, which are related more to deep-seated large-scale structural features of the crust, than to the smaller scale patchwork of the sedimentary deposits.
(2) Hydrocarbon-rich areas tend to be hydrocarbon-rich at many different levels, corresponding to quite different geological epochs, and extending down to the crystalline basement that underlies the sediment. An invasion of an area by hydrocarbon fluids from below could better account for this than the chance of successive deposition.
(3) Some petroleum from deeper and hotter levels almost completely lack the biological evidence. Optical activity and the odd-even carbon number effect are sometimes totally absent, and it would be difficult to suppose that such a thorough destruction of the biological molecules had occurred as would be required to account for this, yet leaving the bulk substance quite similar to other crude oils.
(4) Methane is found in many locations where a biogenic origin is improbable or where biological deposits seem inadequate: in great ocean rifts in the absence of any substantial sediments; in fissures in igneous and metamorphic rocks, even at great depth; in active volcanic regions, even where there is a minimum of sediments; and there are massive amounts of methane hydrates (methane-water ice combinations) in permafrost and ocean deposits, where it is doubtful that an adequate quantity and distribution of biological source material is present.
(5) The hydrocarbon deposits of a large area often show common chemical or isotopic features, quite independent of the varied composition or the geological ages of the formations in which they are found. Such chemical signatures may be seen in the abundance ratios of some minor constituents such as traces of certain metals that are carried in petroleum; or a common tendency may be seen in the ratio of isotopes of some elements, or in the abundance ratio of some of the different molecules that make up petroleum. Thus a chemical analysis of a sample of petroleum could often allow the general area of its origin to be identified, even though quite different formations in that area may be producing petroleum. For example a crude oil from anywhere in the Middle East can be distinguished from an oil originating in any part of South America, or from the oils of West Africa; almost any of the oils from California can be distinguished from that of other regions by the carbon isotope ratio.

There is also the question of how did the spore survive? Billions of tonnes of organic matter dissolved and converted into thick, black gunk but not the spores? I’d have to ask “Why not?”.

Look up thermal cracking. You can even do it in a lab with an oven filled with inert gas (nitrogen would probably do: anoxic environment).
The conversion of plant residue to petroleum oil hypothesis cannot explain the super, super, large petroleum oil deposits for multiple reasons.
Well plant tissue does not form petroleum liquids – that is true. It forms lignite and coal (lignin). While non-plant biological material such as animal proteins and fats produce short chain hydrocarbons when heated under anoxic conditions: thermal cracking. When buried rocks undergo similar processes and the lipids (e.g. fats) undergo cracking and due to elevated buoyancy pressure migrate upwards until they hit a seal => reservoir.

Reply to  cd
December 2, 2014 8:07 am

Are you seriously suggesting that the vast amounts of petroleum discovered underground were created by cracking animal fats? Masses of plants clearly have existed, but it is hard to imagine huge quantities of fatty animals piled up over the eons.
But if “plant tissue does not form petroleum liquids,” then the simplest explanation would seem to be abiotic. The presence of plant spores in petroleum, and even petroleum seeping out of coal beds (mentioned by AP above) do not demonstrate a biological origin; abiotic liquids from below could simply have infiltrated strata bearing remnants of life.

Many algae produce lots of oil when nitrogen starved. They die and are preserved when they sink into dark anoxic bottom waters. Some single cell algae get up to 50% fats once they use up the Nitrogen. (This is done in algae to oil growing operations – then it is easy to convert it to petroleum like products.)
During the early phases of life on earth, there was a lot of algae growing and not much eating it all… So, for example, North Sea oil is likely from just such a stagnant sea of pond scum.
But that does not explain the other more problematic places….
In short, it is easy to get SOME oil from plants (mostly algae). It is almost as easy to get it from F.T. like processes using natural mineral catalysts, carbonate rocks, and deep hot iron rich environment with subduction zones. It is hard to sort out which process might have made what oil a few million (billion?) years later…

I’ve always wondered what should have become of all the other elements during the conversion of formerly living matter to oil.

One of very few known substances in which elemental carbon (coal, graphite, diamond) will dissolve is molten iron. There is a LOT of molten iron in the earth’s core, and it has been molten ever since the planet first formed from a cloud of plasma including elements from hydrogen to uranium in avrious proportions. While there are no known samples of the earth’s core to analyze, there is absolutely no reason to suspect that there is NOT a significant amount of carbon dissolved in the molten iron-nickel core of the planet.

Reply to  tadchem
December 2, 2014 9:20 am

And, Earth’s magnetic field and its periodic reversals prove that an appreciable part of the mostly iron core must be molten rather than some crystalline solid.
As to the S wave speed carbide core hypothetical explanation, the ‘conventional’ alternative explanation is a layer of super hydrated mineral (stored water, in effect) in a core/mantle boundary layer. There is seismic data from major earthquakes that strongly suggests such a layer exists. The Tohoku quake ( which produced Japans recent tsunami and Fukushima) is the most recent to provide such evidence. Which is why this paper says it is providing a speculative but experimentally plausible alternative.
What the speculation does not address is iron carbide in relation to Earth’s magnetic field. I could not find any literature suggesting iron carbide would be magnetic under these temperature and pressure conditions. And the conventional explanation for bulk magnetic propeeties suggests it would not be. Nor is there a proposed mechanism segragating a solid carbide core from a liquid iron core shell, since carbon is soluble in iron–cast iron and high carbon steels being familiar examples.

It has been obvious that the Peak Oil alarm was folly for years. We have run out so often now without anyone but the greens noticing. And now OPEC are currently having to open the taps to try and kill off innovation before the innovation kills them.
But that does not apply to abiotic oil.
Abiotic oil (if it exists, and I suspect it does) has the same flaw as wind or solar power. It is not concentrated in a convenient place. Abiotic oil will be created all over the place at all levels and so needs to be foraged not hunted. That won’t be economic, ever.
As I say, if we have the ability to get at oil at the edge of the mantle, why not use the geothermal energy that’s there? We’ would have solved our energy needs already by the time we can get the abiotic oil.
Apart from the abiotic oil we’ve already found that is indistinguishable from normal oil because it is where we expected to find oil anyway.

I don’t want to get heavily involved in the discussion over the source of most petroleum on the planet, but I will note that Gold’s ideas that oil was produced without the presence of plants did not require that it be abiotic. In fact, his ideas, which were supported by the results of at least one deep drill hole (in Sweden, I think) were essentially that methane interacted with bacteria in the upper few km of the crust to produce liquid hydrocarbons. Thus, the oil was not really abiotic.
That said, there is no substantive evidence that most of the oil we know about is derived from such a process, which is not to say it was not, just that there’s little evidence of such.

A carbon core isn’t as absurd as it may seem at first glance. Carbon is one of the most abundant heavy elements fused in the centers of stars during their lifetimes. After supernovae distributes it into space, all that carbon has to go somewhere. From that perspective it’s far more likely the earth should have a carbon core than an iron one, as we’ve always been taught. Iron is produced in much less abundance.

Carbon-12 is not a heavy element unless you are talking about hydrogen fusion. It’s density (2.6 for graphite at STP) is far lower than iron or nickel (7.8 and 8.9). I think the authors could do a check calculation on the rate of light carbon buoyancy-driven escape from the core to higher strata. How much carbon or iron carbide is left after 4 billion years?

Reply to  Dan in California
December 2, 2014 11:14 pm

In stellar evolution every element other than helium that is fused within stars is considered a heavy element. The relative abundance of fused heavy elements is the point, not its density. Far more carbon is produced in stars than iron. That’s what makes a carbon core for earth a reasonable concept. You’d also expect a lot of hydrocarbons around because hydrogen is the most abundant element in the universe.

Hydrocarbons seep up all around the earth. The dispersion is mediated by faults, the distance down to the shield, and subduction zones.
The amount held in a region is related to the path the Hydrocarbons follow as they rise and the resistance they hit as they near the surface.
In the deserts along the Mediterranean, the sedimentary layers are very tight, allowing very little of the rising hydrocarbons to escape. Lying along one of the most prolific routes which the deeply formed hydrocarbons rise along with the tight sedimentary layer gives the desert states massive stores of hydrocarbons which are continuously being supplemented.
The Saudis do not disclose, or they may not even be sure of the rate of replenishment, but they have a massive reserve which they can profitably produce for $10.00 per barrel.
As they did in the ’80’s, they can bankrupt any attempt to take their market share.
Carter’s attempt at solar, wind, and processed food (corn) were shut down. The current bout will be also.
Areas that do not have a tight cap,such as the Canadian tar sands allow the lighter ends of hydrocarbons to evaporate, leaving only the heavy products.

There is a simple ‘fix’ to the Saudi monopoly practices ( predatory pricing).
Put a tarriff on imported oil (perhaps even just oil from outside N. America so Mexico and Canada are ‘inside’) such that the “landed price” can not be below $80 / bbl. At any price over $80, the tarriff is zero, so has not effect on price of fuels. At any price below $80 (for example, $65 ) the tarriff raises the price to $80 (so a $15 / bbl tax on $65 oil) and prices hold about where they are now (i.e. not much happens).
Yet the oil PRODUCERS domesitcally and the alternatives (i.e. synthetic oils and shale oils and…) are all safe from a Saudi driven shake out with predatory priceing.

E.M. Smith, create an artificially high price for a something and the market will give you a surplus, as we found out when Nixon and Carter tried to control the price of oil in the ’70’s.
Reagan freed the price and after a short, steep rise, the price fell like a stone.
The current surplus was allowed by Opec’s artificilaly high price, not market forces.
The distortion in the market has been caused by Opec and big oil and the greenies wanting the world to believe that hydrocarbons are rarer and more valuable than they actually are and calling them fossil fuels
means that they are finite rather than renewable (on natures schedule).

Jerry,
Please note that this is an adaptive tariff that does not create an artificially high price. In fact, it does nothing to prices inside the defined source oil boundary (either USA or N.America as you like it). There is a fully competitive market inside the bounds. (That is why it only applies to imports from outside the bounds…)
Furthermore, it does nothing to increase price above what it has been for most of the last decade (or two?). Most of the time the tariff does absolutely nothing. Even for OPEC imports. So it will not and can not create an over supply via a price control (as it is not a price control). That is why it only is applied once a price threshold is reached. Nixon and Carter were not doing flexible import tariffs, they were doing domestic price limits / controls. Very different beasts with very different effects. A price control breaks market signals. The import tariff (and one that is rarely imposed at all) leaves market price signals intact (other than removing the ‘die now’ signal from OPEC feeding an oil glut).
What it does do is provide a “countervailing force” to the OPEC monopoly when they decide to try predatory pricing strategies to destroy competitive supply. Only when they drop prices (from the excessive monopoly price they desire) via high production rates and those prices reach levels destructive to our domestic producers; only then would a price floor via that tariff be imposed. (And even that only applies to imported oil from outside the bounds – USA or NAFTA). It is a very focused tool that does little to the domestic market but thwarts the ability to create a price crash by OPEC.
What it does do is assure minor players inside the boundary that they can not be run out of business via the giant monopoly of OPEC artificially pushing prices down. (IF you think they are not artificially pushed down, see the recent OPEC announcement that they were “defending their market share” via continued pumping. That is an explicit statement that ‘price be damned’ they are going to drive someone else out of business. Then they can put the price back up later. This has been done before…)

There are dozens and dozens of observations and analysis results that support the assertion that the abiotic theory for the ‘formation’ of ‘natural’ gas and oil is correct and that we are not going to run out of liquid petroleum or ‘natural’ gas.
I would welcome a debate concerning this subject and can defend Thomas Gold’s hypothesis with observations and analysis. (Note there are dozens and dozens of Russian peer reviewed papers to support Gold’s hypothesis. Gold’s hypothesis is not new (a number of senior Russian scientists formally criticized Gold for not not giving Russian and Ukrainian scientists create for the deep earth CH4 hypothesis). Note the deep earth CH4 hypothesis is used by the Russians to find ‘natural’ gas. The Russians have developed specialized equipment for very, very deep drilling. Note the major oil companies have found massive ‘natural’ gas deposits in very, very deep locations.
Please explain why there is the same ratio of heavy metals in disconnected fields in a region (for example the Alberta fields and the Saskatchewan fields). Why is there heavy metals in the oil? The deep earth CH4 source of petroleum hypothesis provides and explanation for those observations. The deep earth hypothesis provides a pressure source to force the oil through deep mantel rock were it picks up the heavy metals and then moves to the disconnected local field reservoirs.
The deep earth CH4 hypothesis explains why the fraction of noble gases in the atmosphere does not match that found in comets. The big splat removed the light elements from the upper regions of the earth’s mantel and most of the gas (noble gases in particular) in the primitive atmosphere. The fact that the earth is 70% covered with water and the amount of water has increased not decreased with time is explained by the deep CH4 source for liquid petroleum and ‘natural’ gas. The solar wind strips hydrogen from the atmosphere (dissociated H2O). If there was not a continual new source of hydrogen into the atmosphere the earth would be a dry lifeless planet. The CH4 from the deep earth source dissociates in the atmosphere forming H2O and CO2.
The oceans are saturated with very, very, low ratio C12/C13 methane which indicates CH4 continues to be released in the ocean.
As I noted above the alternative to the deep earth CH4 hypothesis is the late veneer hypothesis where comets from a different source than the comets that formed the sun provides the source material for hte earth’s atmosphere and light elements for the atmosphere. The late veneer hypothesis requires the early earth to have a atmosphere density similar to Venus. The geological record does not support the assertion that the early earth had atmosphere of similar density to Venus (under very high pressure chemical reactions are different so there would be geological evidence if there was a very high early earth atmosphere pressure.)
The late veneer hypothesis requires a weird different comet source (there is no observational evidence for the different comet source) to try to explain the why earth’s atmosphere is anomalously low in noble gases as compared to comets or the sun. The late veneer hypothesis requires two independent sources of comets to form the earth (one the comets which now rain on the earth and match the solar composition) and a second comet source that fortuitously provides the late veneer atmosphere of the earth and moves away so it is no longer observed.
The deep earth CH4 hypothesis explains the composition of elements in the earth’s atmosphere. I notice there is no one here or in the peer reviewed literature attempting to defend the late veneer hypothesis in a holistically manner (i.e. acknowledging that a different source of comets is required and the problem of explaining why the different source of comets disappeared), The late veneer hypothesis is not correct (people trying to defend the conversion of plant residue to massive deposits of ‘natural’ gas or liquid petroleum skip the problems of trying to explain the formation and composition of the atmosphere. Note Thomas Gold was a Nobel winning astrophysicist who specialized in planetary formation. There must be a physical explanation for all observations.
There is the fact some major oil fields are refilling which indicates the fields in question are fed by massive lower reservoirs of liquid petroleum. That makes sense as more oil seeps naturally into the ocean each year than is carried by tankers on the surface of the ocean. The liquid petroleum fields in question are still being filled if there is are still connections to their deep earth CH4 source. That is true for some reservoirs and not for others.
In the high latitudes of the planet there is evidence of massive ‘natural’ gas deposits which have not been tapped. We are not going to run out of petroleum or natural gas.
http://www.rense.com/general63/refil.htm

Deep underwater, and deeper underground, scientists see surprising hints that gas and oil deposits can be replenished, filling up again, sometimes rapidly.
Although it sounds too good to be true, increasing evidence from the Gulf of Mexico suggests that some old oil fields are being refilled by petroleum surging up from deep below, scientists report. That may mean that current estimates of oil and gas abundance are far too low.
Recent measurements in a major oil field show “that the fluids were changing over time; that very light oil and gas were being injected from below, even as the producing [oil pumping] was going on,” said chemical oceanographer Mahlon “Chuck” Kennicutt. “They are refilling as we speak. But whether this is a worldwide phenomenon, we don’t know.”
Kennicutt, a faculty member at Texas A&M University, said it is now clear that gas and oil are coming into the known reservoirs very rapidly in terms of geologic time. The inflow of new gas, and some oil, has been detectable in as little as three to 10 years. In the past, it was not suspected that oil fields can refill because it was assumed the oil formed in place, or nearby, rather than far below.

Oil in bedrock granite off Vietnam’s shores
As a result, seven production oilfields were discovered, the largest of which is known as White Tiger, which is on the continental shelf of Vietnam. The main reserve of the White Tiger oilfield is “concentrated in fractured granite basement that is unique in the world oil and gas production practice.” Western oil companies typically expect to find oil only in sedimentary rock. Generally, Western oil companies refuse to drill unless they find “source rock” – sedimentary rock that contains oil the petro-geologists believe derived from decaying ancient biological debris, dead dinosaurs and pre-historic forests. That the Soviets and the Vietnamese have found oil in granite structures is revolutionary, unless, of course, you think from the perspective of the deep, abiotic theory.
he White Tiger oilfield is at a depth of 5,000 meters (approximately 3 miles), of which 4,000 meters (about 2.5 miles) is fractured granite basement. How can the “Fossil-Fuel” theory possibly explain finding oil at these deep levels in granite rock?

Coal, oil, and gas form a continuum of size and complexity of organic molecules, and all are the result of decomposition of complex living molecules by heat, pressure, and possibly micro-organisms. Oil and gas can and do migrate away from the point of origin. Oil pools when its movement is blocked by an impenetrable rock layer; gas moves easier and farther, but moves little in shale (why fracking is used).
Here is an interesting connection. About 300 million years ago, plants developed the ability to make cellulose and lignin, the largest organic molecules that make tall sturdy structures possible. But no existing micro-organisms at that time could break down such molecules. So they accumulated in sediments. Much of the world’s coal and oil were deposited during this period, the late Carboniferous and early Permian (e.g., Permian Basin). When micro-organisms and fungi evolved that could break down such molecules, the rate of fossil fuel deposition greatly lessened.

Donb
December 2, 2014 1:24 pm

P.S. Sediments deposit deepest in basins that are sinking. The deepest know sediments today are >15 kilometers in thickness and located in the southern Caspian Sea and in the western Gulf of Mexico. But sediments don’t stay where they are placed. Tectonic activity can move them up (into mountains) or way down into the deeper crust, and may even intrude igneous rock like granite partially over them.

Isn’t there an obvious connection between biotic and abiotic hydrocarbons? During the Carboniferous, there was possibly lots of abiotic carbon being emitted from the mantle as CO2, methane, etc.
A basic principle of life is to consume all available resources. During the Carboniferous, plants went crazy sucking up all that carbon and creating the huge deposits of biotic fossil fuels we see today.
After emissions backed off, so did plant growth and here we are today. We see the immediate and measurable increase in vegetation due to CO2 additions. Why is is so hard to figure out? Unless you don’t want to.

The standard, if not “consensus”, view is that the spread of large land plants during the Devonian & Carboniferous (originally called the “coal measures”) drew down the high levels of atmospheric CO2 which existed earlier in the Phanerozoic (the “Welsh” Cambrian, Ordovician & Silurian Periods). The lack of fungi meant that this vegetation lay in coal swamps.

Panspermia remains an attractive hypothesis.

Interestingly, there is carbon known in the upper mantle in the form of diamonds. Diamonds occur in stable thick comparatively cool crustal rocks of the Precambrian shields around the world. Diamond pipes are carrot-shaped violent explosive intrusions that have transported diamonds and kimberlite from their source a distance of 150km below the surface in the matter of a couple of hours. It is interesting to speculate that there is a comparatively continuous bed of diamondiferous rock at this depth and that the diamond pipes are just samples of this layer. Also, in fluorite veins mined in Newfoundland and in Kentucky/southern Illinois, and possibly elsewhere, there is some petroleum – a small amount. A ship transporting fluorite from Newfoundland eventually noticed some accumulation of unrefined petroleum in the bilge.

It is of course possible to determine using chemical thermal dynamic analysis to determine whether a chemical reaction will or will not occur, at a specific temperature and pressure (see this attached peer reviewed paper for the analysis). Plant residue will not change to liquid petroleum at the temperature and pressures where the liquid petroleum is found. The fact there is no natural reaction that will convert biological residue to liquid petroleum in the conditions where the liquid petroleum is found is show stopper number one for the biogenic hypothesis for the origin of oil.
The biogenic supporters will not discuss biogenic show stopper number 1 as there is no solution. Perhaps show stopper number 2 would be trying to explain the super, super, large middle east, Alberta, and Venezuela petroleum deposits. (See my above comments for other observations and logic that supports the assertion that natural gas deposits and liquid petroleum are created from deep earth CH4 that is extruded from the core as it solidifies. The high pressure of the core provides the energy to push the CH4 through the mantel. At very high pressure specific metals are picked up and concentrated by the CH4 movement which explains why gold deposits are often found near petroleum deposits and explains why there are heavy metals in some liquid petroleum and explains why there is more heavy metals in ‘heavy’ oil.
As this paper notes chemical thermal dynamic analysis shows that long chain carbon molecules will not spontaneously be formed, except at great pressures (at pressures that occur at roughly 100 km below the surface of the earth.). To support their assertion they perform an experiment that produces long chain hydrocarbons from CH4 using a diamond anvil that can recreate the pressure at great depths.
The following are excerpts from this paper.
http://www.pnas.org/cgi/reprint/99/17/10976

The evolution of multi-component systems at high pressures: VI. The thermodynamic stability of the hydrogen–carbon system: The genesis of hydrocarbons and the origin of petroleum, By Kenney, Kutcherov, Bendeliani, and Alekseev
The scientific problem of the genesis of hydrocarbons of natural petroleum, and consequentially of the origin of natural petroleum deposits, regrettably has been one too much neglected by competent physicists and chemists; the subject has been obscured by diverse, unscientific hypotheses, typically connected with the rococo hypothesis (1) that highly reduced hydrocarbon molecules of high chemical potentials might somehow evolve from highly oxidized biotic molecules of low chemical potential. The scientific problem of the spontaneous evolution of the hydrocarbon molecules comprising natural petroleum is one of chemical thermodynamic-stability theory. This problem does not involve the properties of rocks where petroleum might be found or of microorganisms observed in crude oil.

Natural petroleum is a hydrogen–carbon (H–C) system, in distinctly nonequilibrium states, composed of mixtures of highly reduced hydrocarbon molecules, all of very high chemical potential and most in the liquid phase. As such, the phenomenon of the terrestrial existence of natural petroleum in the near-surface crust of the Earth has presented several challenges, most of which have remained unresolved until recently. The primary scientific problem of petroleum has been the existence and genesis of the individual hydrocarbon molecules themselves: how, and under what thermodynamic conditions, can such highly reduced molecules of high chemical potential evolve?

The expression in the second line of Eq. 2 states further that for any circumstance for which the Affinity does not vanish, there exists a generalized thermodynamic force that drives the system toward equilibrium. The constraints of this expression assure that an apple, having disconnected from its bough, does not fall, say, half way to the ground and there stop (a phenomenon not prohibited by the first law) but must continue to fall until the ground. These constraints force a chemically reactive system to evolve always toward the state of lowest thermodynamic Affinity.

These constraints force a chemically reactive system to evolve always toward the state of lowest thermodynamic Affinity. Thus, the evolution of a chemically reactive, multicomponent system may be determined at any temperature, pressure, or composition whenever the chemical potentials of its components are known. To ascertain the thermodynamic regime of the spontaneous evolution of hydrocarbons, their chemical potentials must be determined.

Maybe I missed it, but I did not see any references to gas hydrates seen in a lot of places offshore just below the ocean floor. Sometimes they are (were?) called bottom simulating reflections because they have the same topography as the sea floor, but lie a short distance below it. Pretty hard to come up with an organic source if the sea floor is basalt or something similar.

IMO the hydrates are found in the seafloor sediments overlying the bedrock.
http://woodshole.er.usgs.gov/project-pages/hydrates/primer.html
How to Find Gas Hydrate
Researchers lack a fully reliable method for locating gas hydrate in marine sediments or the sediments of permafrost regions. Ideally, the existence and saturation of gas hydrate can be inferred without direct sampling (drilling). In marine settings, seismic reflection techniques have long been used to determine the minimum areal extent of gas hydrates. A bottom simulating reflector (BSR) is a negative polarity (seismically-faster material like hydrate-charged sediments over seismically-slower material like gas-charged sediments) “interface” found in some marine sedimentary sections. The BSR is widely interpreted as the base of the gas hydrate stability zone and derives its name from the fact that it often mimics the gross morphology of the sea floor. Because of BSRs represent a phase transition, they often cross-cut the layering of sediments. The existence of a BSR means that gas hydrate almost assuredly occurs in the overlying sedimentary section. However, gas hydrate has been sampled at many locations lacking a BSR. Thus, BSR distribution provides only a minimum estimate of the area in which gas hydrate might occur. To date, BSRs have not been found in areas with permafrost-associated gas hydrates.
A disadvantage of seismic methods for locating gas hydrate is that the saturation of methane hydrate in pore space must generally exceed about 40% for the most common measure of seismic velocity to be significantly altered. This means that some seismic techniques may miss a significant amount of methane hydrate in areas where the saturation is less than ~40%. Laboratory studies show that electrical methods are more sensitive to lower saturations of gas hydrate. This has fueled interest in the application of electromagnetic (EM) methods for regional characterization of gas hydrate deposits or the joint application of EM and seismic techniques. The sensitivity of electrical properties to a wide range of hydrate saturations is also manifest by the widespread reliance of borehole resistivity logging to identify hydrate-bearing sediments in both marine and permafrost-associated settings.

The bottom simulating reflection as much as 500 ft above the layer of methane hydrates which is as much as 500 meters thick off the coasts of the US.
The amount of gas contained therein equals thousands of years of energy for the US when the market discovers a safe way to recover it.
The answer is likely to be simple, but dangerous to ascertain. The best candidate I have read about to date is using CO2 to free the methane from the clathrate cage.
The source of the gas is the upwelling from below.
No biological mass from above is allowed to accumulate.
As seen in the huge BP spill of gas and oil in the Gulf, the massive plume which greenies expected to last for years, was eaten by a massive microbe bloom within three months of the cessation of the spill.
Give the microbes hydrocarbons to eat, and they bloom to the limit of the food.
The methane could be cat cracked into much more portable and more stable fuel such as diesel or ethenal with a modest expense of BTU’s to convert

Tom Bakewell KE7AVZ
December 3, 2014 12:10 pm

Thanks for the above comments. The point I wanted to make is that clathrates are found in areas where no reasonable biogenic source can be found. That seems to add evidence to the aboigenic model as proposed by Gold. It may not be the only source for hydrocarbons, but it may be one of several sourcing mechanisms.

Vladimir Larin hypothesized, with a great deal of data analysis, the concept that the Earth (and other terrestrial planets) congealed from an interplanetary medium that was mostly hydrogen (plausible). This means the planetary cores were composed of metallic hydrides, which are far more compressible than elemental metals. Under energetic stimulus (e.g., radioactivity) the hydrides break down into hydrogen and elemental metal. The hydrogen diffuses out of the core toward the surface, reducing available carbon, nitrogen, and oxygen into methane, ammonia, and water and driving them upwards out of the crust. (Incidentally, the increasing metalization of the core causes it to expand, leading to a steadily increasing Earth radius.) It is a very interesting theory, worth reading about.
J. Marvin Herndon has a somewhat competing theory in which the Earth formed with an initial overburden of gas giant atmosphere, later blown away by solar wind. (He bases his model on an analysis of the chemical composition of meteorites.) The overburden compressed the earth and infused methane into the crust (also leading to planetary expansion on the rebound). Planetary mass segregation also formed a natural fission reactor in the core, which drives the planetary magnetic field.
Larin and Herndon would probably argue with each other all night long, but what is interesting is that their theories are not necessarily exclusive. It goes to show that alternatives to the conventional view are available if you are willing to look for them and consider them.
(By the way, don’t argue with me over their views. Argue with them. Read their books first to understand what evidence they can bring to the subject. Uninformed argument is, well,…nothing commendable.)

Check out his web site as it is still available: http://www.metaresearch.org/publications/books/books.asp

Dr. Tom Van Flandern died in 2009 age 69, a true scientific loss. But there is so much on his website that is still available to view. Van Flandern developed the exploding planet hypothesis. There is also much on the GPS system on the site here: http://www.metaresearch.org/cosmology/gps-relativity.asp

But I thought the generally accepted theory was that the entire Solar System was formed from the accretion of junk dumped by early space travellers. (In contrast to the wild claim that the Earth was constructed by the Magratheans.)

Dare I point out that “generally accepted theory” = “consensus science”? And what website is this, again? There are prevailing theories, based on King of the Mountain strategies for selecting supporting evidence, but, sadly, astrophysics is almost as badly compromised as “climate science” and Darwinism: lots of pompous claims of settled science and a complete lack of discussion of the evidence that does not fit. Were you aware that Edwin Hubble did not agree with the hypothesis (named after him, ironically) that interstellar redshift was due to the Doppler effect of recession velocity? (“It’s assumptions, all the way down.”)
