GREENFIELD EXPLORATION PROSPECTS OF OROGENIC GOLD MINERALIZATION IN AND AROUND LAWA AREA, NORTH SINGHBHUM MOBILE BELT, EASTERN INDIAN CRATON

Palaeo to Meso proterozoic North Singhbhum Mobile Belt (NSMB) refers to an assembly of The multiply folded, low to medium grade meta-sedimentary and meta-igneous rocks of Proterozoic age (1.0?2.4 Ga) lying between the Archaean Singhbhum Craton also known as Archaen Cratonic Core Region (ACCR>2.4 Ga) in the south, and the Meso/Neo-Proterozoic (0.9?1.7 Ga) Chotanagpur Gneissic Complex (CGC) in the north. The NSMB and the CGC are separated by the Tamar?Porapahar?Khatra?Fault (TPKF), also referred to as the Northern Shear Zone (NSZ). Further to the south, the NSMB and the Singhbhum Craton is separated by the Copper Belt Thrust (CBT), referred as the Southern Shear Zone (SSZ). In the northern part of the NSMB, mica schists fringing the CGC document a northward increase in strain and temperature (greenschist to amphibolite facies).
