Geodynamic situations of basalts formation on Tykotlovskaia aria (the Pre-Polar Urals)

Formation of Tykotlov unit of Upper Ordovician basalts was accomplished in the limits of the Western-Tagil zone. The paleogeodynamic situation in the zone corresponded to margin spreding sea according to composition, age of volcanic rocks and petrochemical diagrams. That is the reason why Tykotlov area is the perspective one for sulphide gold-polymetallic ore.
