The Bazhenov formation is presented by the Late Jurassic black shales. Russia is on the first place on the reserves of “shale oil” that is mostly connected with the Bazhenov formation. For the reconstructions of sedimentation environments of the main types of the formation rocks the REE distributions have been used. The results point out to the formation of the Bazhenov deposits in relatively shallow environments - within the limits of inner and outer shelf of the epicontinental sea, the type of the Kara or East-Siberian Sea, relatively deep-water part of which is located north of the Latitudinal Priobye. These results confirm some previous estimates, but have been obtained on the base of quite different independent data. The geochemical study of different types of rocks of the Bazhenov formation gave the identical results that testify in favor of reliability of the results obtained.

The Bazhenov Formation of Western Siberia is one of the most important and promising high-carbon formations. Its peculiarity is a huge area of distribution and high generation potential of its constituent deposits. Another feature of the formation is the predominance of silicides in its composition, among which the most interesting are radiolarites, which are often associated with hydrocarbon inflows. However, the mechanism of the forecast and the nature of their distribution still do not have an unambiguous solution. Based on a study of the composition and textural features of the structure of radiolarite layers in the clayey-siliceous rocks of the Bazhenov formation, a model of their formation based on the interaction of plankton (radiolarians) and currents is proposed.
