P148-TU MAJOR CENTERS OF HYDROCARBON GENERATION IN THE PROTEROZOIC AND PHANEROZOIC OF THE SIBERIAN PLATFORM

Several centers of naphthide generation have been distinguished in the Siberian Platform (Fig. 1) and their tectonic evolution and the modern characteristic of their oil source formations have been considered (Kontorovich et al., 1999). Figure 1. Oil and gas generation centers in Precambrian and Phanerozoic sedimentary basins of the Siberian Platform (1 – outlines of the Siberian Platform, 2 – major oil generation centers, 3 – areas of anomalous rock heating under the influence of trappean intrusions). Geochemistry of oils and bitumens of the Siberian Platform and the eastern areas of the West Siberian plate has been studied (Kontorovich et al., 1999, 2000, 2005, Kontorovich et al., 2001, Timoshina, Kim, 2005). Based on the presence or absence of 12-, and 13-monomethylalkanes, distribution of steranes, terpanes, and isotopic and various physicochemical characteristics, oils are divided into realms and families. The differences in the composition of oils confirm the existence of numerous centers of naphthide generation with specific biocenoses and their different evolution after burial in the Siberian Platform in the past.
