Geologicheskii Vestnik

To date, there is no doubt that in the Paleozoic the crust of the Urals was formed in a setting of tangential compression as a result of manifestations of several tectonic cycles, each of which was due to the thrust of the oceanic crust on the continental base. As a result, the geochemical interaction of the compositions of volcanogenic-sedimentary formations, which evolved in accordance with the increase in tectonic compression from minimum to maximum values, was determined. Significantly increased tectonic loads lead to squeezing of eruption channels, cessation of magmatic activity, widespread development of flysch and olistostromal strata, massive thrusting and digging of previously formed formations, and the appearance of anatectic granite intrusions. The first half of the tectonic cycle, as a rule, evolutionary, led to the development of igneous rocks — the main carriers of ore components in a dispersed state. The second half is deformation, in addition to the listed processes, it contributed to the concentration of useful components in one way or another in the deposit. In accordance with the model of the formation of the earth’s crust, the epochs of ore formation are simultaneous with the thrusting and are genetically determined by it.
