Features of the North Ural sedimentary basin Paleozoic history

On the basis of new sedimentation data, regularity of cyclic sequences formation and facies distribution evolution of the Paleozoic North-Ural sedimentary basin is characterised. Reconstruction of environment conditions are spent taking into account new representations about the stratigraphy of the Paleozoic deposits. Are shown some event boundaries that were changing of sedimentary basin framework and new sedimentary models are presented.
