pdf  Lithology and sedimentary environments of the Upper Visean - Lower Permian strata of the Pechora offshore
The lithology and sedimentary environments of the Upper Visean - Lower Permian carbonate strata of the Pechora Sea are described. The lithofacial schemes and lithostratigraphic section are presented. The two main sedimentation phases are revealed: the Late Visean - Serpukhovian and the Middle Carboniferous – Early Permian. There is a break between these phases which confined to the Early Bashkirian time. Both phases are characterized by reefogene building. During the Late Visean – Earlier Permian the area of reefs distribution was gradually shifted from the north-east to the north-west and west. In Carboniferous - Early Permian section shallow sea environments were replaced by relatively deep environments.
Key words: carbonate rocks, lithology, sedimentary environments, lithofacial schemes, Pechora shelf.
