摘要: The late Archaean Closepet granite of southern India is bounded by N-S trending shear zone. At the end both charnockite and veins are spatially associated with ductile shears. These shears continue further north confined to contact zones in central part outcrop. main component zone highly deformed sheets, augen gneisses mylonites. Field observations microstructural fabric mylonites indicate a dextral sense movement. evidence suggests that deformation was active throughout evolution
