Electromagnetic images of the Proterozoic Bhima basin, India

Abstract:

The Purana Basins are unique feature of Proterozoic geology of Indian Peninsular Shield that include almost un-deformed and un-metamorphosed sediments that occupy more than 20% of the area of Precambrian exposures. Among the seven Proterozoic basins in India, Bhima basin is the youngest (600 ma) and its deeper structures are the least studied geophysically. The sediments occupy an area of less than 5000 sq km; the lithosequence is essentially constituted of limestone units of undisturbed horizontal beds. The basin is located on the northern edges of Eastern Dharwar craton comprising Peninsular Gneissic Complex, intrusive granitoids and a series of subparallel greenstone belts. The initiation of Bhima basin was related to regional tectonism related to Eastern Ghat Mobile Belt (EGMB) and Mid-Proterozoic Mobile Belt (MPMB) orogeny. To the North of the Bhima basin is finalized by the volcanic units of …
