NAPHTHIDE SHOWS IN THE VENDIAN AND CAMBRIAN DEPOSITS PERMAFROST (NORTH-EAST OF THE EAST SIBERIAN PLATFORM)

Abstract

This paper discusses the features of the organic geochemistry of natural bitumens and scattered forms of naphthide shows in the Khatyspytskaya, Turkutskaya formations of the Vendian and the Kessyusinskaya formation of the Lower Cambrian of the Olenek saddle (north-east of the Siberian platform). It is confirmed that the source of these bitumens was the organic matter of the Khatyspytskaya formation. It was shown that not only bitumens in the dolomites of the Turkutskaya sediments, sandstones and gravelites of the Kessyu sediments are oxidized by bacteria, but also the para-thromic bitumoids of the Khatyspytskaya formation are biodegraded in the hypergenesis zone.

Keywords: organic geochemistry, oil-producing rocks, naphthides, biomarkers, biodegradation, Vendian, Cambrian, Siberian Platform.
