pdf Paleogeography of the Pechora-Barents Sea paleobasins in the Late Ordovician-Early Devonian
Modern studies have made it possible to clarify and detail the overall picture of paleogeographic development and establish the basic patterns of the structure of Upper Ordovician-Lower Devonian sedimentary column in the Pechora-Barents Sea megabasin. The strata of the Upper Ordovician, Silurian and Lower Devonian are divided into 10 sedimentary sequences reflecting cycles of fluctuations in the level of the 3rd order of the World Ocean, lasting from 4 to 10 million years. The identified sequences made it possible to compare different facies in the sedimentation basin and confirm the conclusion about the existence of a single Pechora-Barents Sea megabasin in the Ordovician, Silurian and Early Devonian. Based on the analysis of facies maps, extensive and prolonged transgressions and the most pronounced regressive stages in the development of the basin have been identified.

Keywords: facies, sequence, paleogeography, Late Ordovician, Silurian, Early Devonian, Pechora-Barents Sea paleobasin.
