Good since Syzgys is out of the way & done with this conversation, let's us just bid him farewell yet again, and don't let the door hit you on your ass on the way out!
Here's a bit of scientific data that presents my case that abiotic oil is possibility of existence.
n a report of the US National to the IUGG :
" New evidence from field, laboratory and quantitative studies has firmly established that in geologic-time scales lateral fluid migrations within sedimentary basins can occur over length scales of hundreds of km and vertically through crystalline rocks to depths greater than 6 km". (American Geophysical Union, 1995)
In a lecture Kropotkin (1985) presented some interesting arguments in favor of a non-biogenic origin of petroleum especially the studies of Boiko, Eigenson and Gold.
G.E.Boiko studied the relations of isomers in the hydrocarbon system from 322 oil samples from various fields of the world and the result of these analyses was published between 1950 and 1975. The thermodynamic calculation of the complete hydrogen composition of oil has shown that it is in equilibrium state at a temperature of 1600 to 1800 degrees Kelvin and pressures of 2 to 4x 10³ Mpa. Oil of geosyncline and platform areas does not differ significantly in the temperatures corresponding to this equilibrium composition. Boiko concluded that the synthesis of oil takes place in the upper mantle at a depth of 40 -160 kilometers. In any case it could not be synthesized within the sedimentary blanket where temperatures and pressures do not correspond to the isomeric relations characteristic of all oils.
Theories of a biologic origin are based on the presence of so-called molecular fossils, like phophyrin complexes. Chlorophyl in green plants is magnesium phophyrin. Eigenson wonders why in oil no even traces of iron and magnesium complexes have been found, but only vanadium and nickel ones.
The discovery of oil, deep in crystalline rocks of the Baltic shield is an strong argument for the abiogenic origin of oil. Gold (1997)
Gold (1992,1994,1996,1997) is a strongly believes that hydrocarbons have been formed in deeper parts of the Earth by non-biological processes. He thinks that the biological origin of some sets of molecules (hopane, pristine,phytane, steranes and certain porphyrins) found in all commercial oil are not of the biological origin of the oils themselves, but equally well or better by a contamination with microbial (bacteria) materials in all oil wells. The stability of hydrocarbon molecules against thermal dissociation is greatly increased by pressure.
Gold does not have much support in Western scientific world with his provoking ideas. This will not prevent us to mention his ideas. It is anyhow worth thinking of the possibility.
He mentions arguments in favor of an origin of petroleum from deeply buried material incorporated in the Earth when it formed:
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 smaller scale patchwork of 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 on an area by hydrocarbon fluids from below could better account for this than the chance of successive deposition.
3. Some petroleum from deeper levels lack almost completely the biological evidence
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 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 of the geological ages of the formations in which they are found. Crude oil examples anywhere from the Middle East can be distinguished from oil in any part of South America or from the oil of West Africa.
6. The regional association of hydrocarbons with the inert gas helium and a higher level of natural helium seepage petroleum -bearing regions have no explanation in the theories of biological origin on petroleum.
(Helium has two isotopes. Helium 4 is formed by radioactive decay of uranium and thorium, while helium-3 was present at the time the earth was formed. Its transport from deeper to lower parts of the crust is dependent on hydrocarbon gas. Helium 3 is present in volcanic rocks that are spewed up by the so-called upwellings from deep inside the earth that give rise to the islands chain of the midoceanic ridges such as the Hawaiian islands. Commercial helium is produced from oil and gas wells).
Gold has shown horizontal and vertical patterns of hydrocarbon fields. First, he points to the fact that the 2700 km long oil-rich belt in the Middle East is composed of completely different geological and topographic features. The various oil deposits are in different types of rock, in rocks of different ages and quite different cap rocks overlie them. "It cannot have been a matter of chance that this connected region has so prolific a supply of oil and gas, but resulting from totally different circumstances in different parts of the region. Very remarkable is the fact that the chemical composition of the Middle East oil is similar over the whole region".
