Paleoproterozoic granitoids of the Don terrane, East-Sarmatian Orogen: age, magma source and tectonic implications

The Pavlovsk complex granitoid plutons and associated gabbro-diorites are confined to the East Sarmatian Orogen (ESO) that compose the western part of the junction between the Sarmatian and Volgo-Uralia segments of the East-European Craton. The plutons form the largest batholiths with an area of up to 2000 km2 and a total length of more than 330 km. The conditions for their emplacement and crystallization, sources of melts and tectonic position...
