New data on absolute age, petrology and potential of ore mineralization within Murzinsky intrusive massif (northwestern Altai)

The geological, petrogeochemical data, absolute age dating and information about endogenetic ore mineralization of Murzinsky intrusive massif of Altai are presented. Comparison of rock compositions and melanocratic inclusions suggests that gold potential of deep spot melting is related to hybrid melts forming as basalt and crust acidic magma mixed. Along with skarn, the ore field could host copper-gold-porphyry mineralization. Gold was supplied from acidic melting as a result of amphibolites and lower crust greywacke melting.
