Minerageny of the Ufalei Block (Middle Urals) in Connection with Lithotectonic Complexes of Different Geodynamic Settings

摘要

The relatively well-studied Ufalei Block represents a key structure for understanding the genesis and economic potential of other similar blocks: Sysert, Il'menogorsk-Vishnevogorsk, Marunkeu, and others. The available geological and radiological data [1-6 and others] and original materials show that the Ufalei gneiss-amphibolite complex (Fig. 1) underwent several stages of structural-tectonic and metamorphic transformation, each accompanied by the formation of particular igneous complexes, which produced carbon-atites, pegmatites, different metasomatites, vein quartz, and other rocks during the postmagmatic stage (table).
