2022年3月1日 · The Singhbhum Shear Zone (SSZ), a ~150 km long and 1-5 km wide thrust zone in between the NSFB and SC cut across rocks of the IOG, the Singhbhum Group, and the Dhanjhori Group (Sarkar and Saha, 1962), and is considered to be formed in between 1.9 Ga and 1.0 Ga (Johnson et al., 1993; Pal and Rhede, 2013; Pal et al., 2021).
Geospatial Mapping of Singhbhum Shear Zone (SSZ) with Respect …
The shear zone is characterized by extreme ductile shearing, multiple metasomatism, migmatisation and prominent mineralization of copper, uranium, tungsten and phosphate. The bulk of the shear zone material is made up of pelites and volcanic clastics, probably gener- ated during the Dhanjori and Koira depositional cycles.
