CARBONATE SEDIMENTATION IN THE UPPER JURASSIC OF WESTERN SIBERIA AND ADJACENT TERRITORIES
An overeview of the published data on the distribution of carbonate rocks in the Upper Jurassic deposits of the West Siberian plain and its frame is presented. As a result of the lithological studies established, that most of the carbonate bodies in the marginal parts of the basin was formed by the development of algae with lime-micritic shells in a lagoon and screened marine shallows, except for reef-like structures and organic banks on the seahills. It is assumed, that the region of the Upper Jurassic carbonate sedimentation stretched from Europe to Western Siberia.
