| Popis: | At the poorly studied area of Northern Urals the Early-Paleozoic volcanic complexes were allocated, dated and characterized. Volcanic rocks in researching area were formed during period from Late Ordovician to Early Devonian and were attributed to Palnikshor (Vyja), Shemur, Pavda, Imennya and Sos’va (Tura) formations. The greatest attention was paid to Silurian volcanic strata; it was found that they are do not differ from the Pavda and Imennya formations of Middle Urals by the age, facies features and geochemical parameters. Rocks of sulphide deposits bearing Shemour formation have a low scale at the researching area, so it is not possible to predict the presence of large and medium cupper deposits. |
