PECULIARITIES OF ACCUMULATION IN NAPHTHYDES OF VANADIUM AND NICKEL
The regularities of the content of V, Ni, their ratios, as well as the concentration of vanadium and nickel metalloporphyrin complexes in the oils of various oil and gas bearing basins and oil and gas bearing regions are considered in the article. It is shown that the distribution features of these elements are genetic indicators that characterize the ontogeny of hydrocarbon clusters. The nature of the distribution of vanadium and nickel in oils is due to both the primary processes of oil formation (the type of the initial organic matter, the oxidation-reduction conditions at its disposal) and the secondary transformations of naphthydes in the Earth's interior (hypergenesis, migration, catagenic transformation).
