U-Pb Zircon Age of the Gold-Bearing Seredovina Massif, Middle Urals

摘要

The Seredovina gold-bearing massif is located in the Middle Urals, 2 km southeast of Nev'yansk in the well-known Nev'yansk gold district and is confined to the outer contact of the large Verkhisetsk tonalite-gra-nodiorite batholith (Fig. 1). The massif is a typical minor granitoid intrusion localized in the apical part of batholith-shaped bodies, which usually contains dike fields with gold-bearing quartz veins and wallrocks composed of listwaenite-beresite metasomatites. The massif hosts the Nev'yansk Seredovina quartz-sul-fide gold deposit.
