Mineral Chemistry and P-T Conditions of Formation of A Basic Scapolite-Garnet-Pyroxene Granulite from Doddakanya, Mysore District
Subscribe/Renew Journal
Electron microprobe analyses of coexisting phases in a basic scapolite-garnet-hornblende-two-pyroxene granulite from a Sargur supracrustal enclave near Doddakanya are presented. The results of various mineral geothermometers and geobarometers indicate temperature and pressure conditions of 810±20°C and 9.5 ± 0.5 kbar during metamorphic reequilibration. A comparison with other data from granulites of southern India shows that granulite-facies metamorphism of relatively high pressure is a common feature of the granulite region of the Archaean shield.
