The Chotanagpur Granite Gneiss Complex (CGGC) of the East Indian Shield records a protracted geological history ranging from Palaeo- to Meso- to Neoproterozoic time. It is commonly believed that the whole of the CGGC behaved as a unified crustal block at least from 1600 Ma (ref. 3). The E-W to ENE-WSW trending North Purulia Shear Zone (NPSZ) dissects and geographically divides the CGGC into the northern and southern blocks.

Abstract


The Chotanagpur Granite Gneiss Complex (CGGC) of the East Indian Shield records a protracted geological history ranging from Palaeo- to Meso- to Neoproterozoic time. It is commonly believed that the whole of the CGGC behaved as a unified crustal block at least from 1600 Ma (ref. 3). The E-W to ENE-WSW trending North Purulia Shear Zone (NPSZ) dissects and geographically divides the CGGC into the northern and southern blocks.
