There took place cardinal paleo- and zoogeographic changes in the second half of the Permian period and the beginning of the Triassic on the east of the East European Platform. These changes have been reflected in the geochemical features and magnetic properties of the rocks, the isotopic composition of chemical elements, the characteristics of the fauna, as well as the nature of the sediments. Permian sediments complete have an extremely complex geological structure, are characterized by a diversity of lithologic-facies composition and occurring of specific minerals, which are considered indicators of various types of lithogenesis (sulfate-carbonate rocks, coals, copper sandstones, schists, etc.). Based on lithological and paleomagnetic studies, paleogeographic reconstructions were performed. They showed that one of the factors of Perm sedimentation and related processes of the formation of ore and nonmetallic minerals are global climatic changes caused by Carboniferous-Permian glaciation.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
