THE RIPHEAN METESHIKHA ISLAND-ARC PERIDOTITE-GABBRO MASSIF (western Transbaikalia) [PDF]

Геология и геофизика, 2015
Abstract New data are presented on the geologic structure, age, petrogeochemical composition, and conditions of formation of the Late Proterozoic Meteshikha ultramafic–mafic pluton of the Ikat complex. Mafic rocks are the main rocks of the massif, whereas ultramafic rocks are secondary; both of them correspond to two intrusive phases ...
