Composition of the typical section of the lower carboniferous deposits of the eastern subzone of the Lemva zone (Polar Urals): part 1. Lithological marker

The composition and structure of the Lower Carboniferous part of the Yajyu Suite, common in the eastern subzone of the Lemva structural-formational zones of the Urals is given. It is an indicator of collision processes beginning in the northern part of the Urals and it reflects the geological history of this period. The scaly-thrust structure of the region, small isoclinal folds, numerous discontinuous disturbances and redeposition of organic remains strongly obscured layers succession. The discovery of the lithological marker allowed to decipher the geological structure of one of the tectonic «scales» (plates).
