New data on the biostratigraphy and facies types of upper carboniferous Domanik sections in the Volga–Ural basin

Abstract

New data on the biostratigraphy and facies types of Domanik sections in the Volga–Ural basin are discussed with the description of four types of sections that reflect different depositional environments: the shelf of a carbonate platform, biogenic buildups (bioherms) of its outer zone, slopes of depression, depression. Paleontological remains made it possible to determine the age of the host rocks. Such information serves as a basis for modeling the formation of Domanik deposits and reconstructing their paleogeographic settings.
