MELTING CONDITIONS OF GRANITOID XENOLITHS IN CONTACT WITH ALKALINE MAFIC MAGMA (GUSINOOZERSKAYA DYKE, WESTERN TRANSBAIKALIA): TO THE PROBLEM OF THE ORIGIN OF ULTRAPOTASSIC ACID MELTS

MELTING CONDITIONS OF GRANITOID XENOLITHS IN CONTACT WITH ALKALINE MAFIC MAGMA (GUSINOOZERSKAYA DYKE, WESTERN TRANSBAIKALIA): TO THE PROBLEM OF THE ORIGIN OF ULTRAPOTASSIC ACID MELTS

The alkaline mafic (lamprophyric) Gusinoozerskaya dyke in West Transbaikalia is composed of partially melted granite xenoliths. Among the xenoliths, two melted substrates are observed: (1) plagioclase and quartz, and (2) alkaline feldspar and quartz. Few millimeters thick microfelsite and micrograno...
