Based on results of deep drilling and the CDP-2D seismic profiling, the relations between the Early and Middle Cambrian carbonaceous rocks and the underlying, overlying, and synchronously formed deposits in the Siberian Platform are analyzed, and the lithologo-paleogeographic, paleotectonic, and tectonic conditions of their formation are considered. It is shown that these carbonaceous rocks are intimately related to the Cambrian organogenic structures, up to their mutual transitions.

We analyze geologic and geophysical factors enhancing the prerequisites for the high petroleum potential of East Siberia that were formulated by A.A. Trofimuk in 1960. The main updates concern the northern Siberian Platform, where it is indeed possible to significantly increase its petroleum potential and to refine the localization of large and giant, mostly oil accumulations.
