However there may be better ways of educating oneself than relying on Gold's website for info. A Google search brings up this article:
The particular subject of this article is the application to such evaluation of the modern Russian-Ukrainian theory of abyssal, abiotic petroleum origins, an extensive body of knowledge which has been developed and applied during the last forty years. 1996
One of the citations is:
Kropotkin, P. N., Ed. (1956). Origin of hydrocarbons of the Earth's crust.
Apparently, Gold got his theory from the Russians, not the other way around.
Q: Were there precedents for your idea that deep hydrocarbons are a normal fact of planetary geology?
Gold: In the '60s, Sir Robert Robinson [a Nobel Prize-winning chemist and president of Britain's Royal Society] said that petroleum looks like a primordial hydrocarbon to which biological products have been added.
Q: And what was the response?
Gold: The response was that I quoted his remark in many of my papers. But the profession of petroleum geology did not pick it up. Mendeleyev [the Russian chemist who developed the periodic table] in the 1870s had said much the same thing, but Robinson had done a more modern analysis of oil and had come to the same conclusion. And, in fact, the Russians have in the last 20 years done an even more precise analysis that completely proves the point. The fact that Mendeleyev was in favor of a primordial origin of petroleum had a great effect - you see, to most Russians, Mendeleyev was the greatest scientist that Russia ever had.
