Geochemistry of Metamorphism in the Malikhera-Mokanpura Area of Dariba-Rajpura-Bethunmi Polymetallic Sulphide Belt Rajasthan

The present paper deals with geochemistry of metamorphic aspect of the rocks of the Malikhera-Mokanpura area. The rocks are metamorphites in nature and are characterized by a varied key metamorphic minerals and mineral assemblages. An attempt has been made to work out the various mineral assemblages to ascertain the metamorphic facies and zones. Estimates of pressure and temperature conditions operating during the formation of metamorphic assemblages have been made. The lowest grade of metamorphism attained by these rocks rajpura-Dariba area is of quartz-albite-biotite sub facies of the green schist facies The highest is staurolite-almandine sub facies of amphibolite facies in the Barrovian type of metamorphism
