Abstract

Summary

The research objective was to analyze the capabilities of Sm-Nd isotope geochemistry for the characterization of source rocks on the example of the Bazhenov Formation. The chosen geological object is a part of the Upper Jurassic deposits in the Northern region of the Bazhenov Formation. Compared to the well-studied Bazhenov cross-section in the central part of Western Siberia, the cross-section in the North region has a more complex structure with interlayering of intervals of different genesis, characterized by different oil generation potential. The comprehensive comparative analysis of the data on the Sm/Nd and143Nd/144Nd with results of the lithological, petrophysical, and geochemical study shown the considerable difference in the sources of inorganic components of different lithological members. Obtained results allowed us to suggest the changes in preferential direction of continental runoff from the East (Eastern Siberia) and the West (Ural) during the period of sedimentation.
