| Abstract: | In view of the development of the naphtide polygenesis concept including the role of endogenous fluids in the processes of
oil accumulations, the applicability of several geochemical coefficients characterizing the ratios of microelements (MEs)
in oil is considered in order to identify the oil sources. By means of discrimination diagrams drawn for the average ME concentrations
in oil, including the distribution coefficients of impurity elements in the systems of the melts of various alkalinity (rocks)
and fluids (bitumens), it is shown that the oils of different regions are considerably different in their geochemical features. |
