SM-ND AND RB-SR DATING OF HIGH-PRESSURE METEGRANITES IN THE EAST URAL UPLIFT, THE SOUTHERN URALS

Abstract

The problem of eclogite formation occupies an important place in paleodynamic reconstructions of the geological history of the Urals. To date, the overwhelming majority of researchers have accepted that the eclogite–glaucophane schist complexes in the mobile belt are related to the subduction-related and collisional geodynamic regimes. The age of high-pressure metamorphic rocks and their localization in regional geological structures represent key evidence in deciphering the convergent motions of lithospheric plates at various stages of the mobile belt evolution.
