Abstract
Based on the correlation analysis, the article examines the relationship between the trace element (TE) composition of naphthides, which includes the carbonaceous matter of sediments (bitumoids), oils of various oil and gas basins (OGB), asphalt-resinous components of oils and solid natural bitumens with the compositions of the Earth's crust at different levels and biota. For comparison, similar correlations of the TE composition of coals and shale formations are also given. New relationships have been revealed between the values of the correlation coefficients of the compositions of the studied natural substances, which make it possible to use the TE tag as a genetic reference for characterizing natural processes on the evolutionary scale of oil generation.
Materials and methods
Research materials: naphthides of various genesis — bitumoids of organic matter of rocks, oil, resinous-asphaltene components of oil in the oil and gas basin, natural bitumen, earth crust, shale and biota. Research methods: Using the methods of mathematical statistics, we calculated the correlation coefficients between the TE composition of the objects involved, based on the analytical database of a large number of researchers. Drawing up tables and graphs.
