THINKING OF INORGANIC ORIGIN THEORY ON PETROLEUM

This paper,on the basis of the puzzling kerogen pyrolysis theory,discussed Pb-Sr-Nd isotopic data in the bitumen and kerogen.Pb-Sr-Nd isotopic data don't support the theory which petroleum (bitumen) derived from kerogen.The bitumen in the Tarim basin was from the lower crust but the bitumen in Karamay was from the upper mantle.The discovery of organic silicon compounds in the oils shows that the oils might be synthesized by inorganic interaction in deeper crust or upper mantle.This paper presents an oil (gas) generation hypothesis of organic matter plus inorganic hydrogen.The uncertainties of carbon isotopes showed that carbon isotope is not a reliable tracer.At present,inorganic petroleum theory can be applied to the further petroleum exploration.
