Vendian of the Middle Urals: A review of some investigations in the beginning of the 21st century

Research subject. The research objects included a book section on the Vendian stratigraphy of Yazvinsko-Kosva sub-zone Kvarkush-Kamenogorsk meganticlinorium, written for Explanatory note to sheet O-40 – Perm State Geological Map 1000/3 Russian Federation, as well results obtained in course various thematic (stratigraphic, paleontological, litho- and isotope-geochemical, etc.) studies sedimentary sequences indicated territory. Materials methods . materials were facts, ideas arguments favor certain conclusions authors. analyzed. comparison analysis predecessors. Results It is suggested that about architecture deposits western slope Middle Urals, dating back pioneering works B.D. Ablizin his colleagues, had almost reached perfection. At same tim, attribution different formations regional stages East European Platform still interpreted differently. Studies into macrofauna Urals have also made significant progress first two decades 21st century, which, however, cannot be said microfauna. detrital zircons from tillite-like conglomerates sandstones Serebryanka Sylvitsa groups should undoubtedly continued. For volcanic tuffs/ashes, search correlations already dated igneous bodies with sequences, relevant. This complicated by mountain taiga conditions. prospects studying chemical composition heavy fraction minerals, reconstructing evolution clastic sources groups, seem boundless. Conclusions conducted published years century aspects geo logy it possible identify their strengths weaknesses outline directions further research.
