Formation of Traps and Hydrocarbon Deposits of the Southern Part of the Siberian Platform

In the article, the author analyzes the conditions of traps and deposits formation on the Nepsko-Botuobinskaya anteclise to clarify the factors affecting the productivity of deposits, affecting on the way of fluid migration to potential areas. The tectonic factor played a special role in the formation of traps and deposits. Also, part of the depositsis controlled by the lithological factor. All this causes the variety of traps currently available. The author considers the geological structure of the anteclise from the point of view of paleotectonics and provides diagrams of the types of deposits in the territory, as well as shows schematically the faults along which further migration of fluids is possibleto nearby territories. The widespread development of fault-block tectonics has a direct impact, both positive and negative, on the development and exploration of deposits associated with tectonic elements.
