Gravity Surveys for Barytes Around Mangampeta, Cuddapah District, Andhra Pradesh

The barytes deposit of Mangampeta (14°01'15" : 79°19'15") may now be classed as the largest single barytes deposit in the world. Though the occurrence of barytes in Mangampeta was known since mid-sixties, a multi-disciplinary approach including gravity surveys carried out during 1971-73 revealed the immense potentialities of the deposit. Exploratory drilling at the recommended points over the gravity' high' struck thick zones of barytes. As many as 61 boreholes have so far been drilled over the main gravity: anomaly zone, of which 53 intersected barytes ranging in thickness from 5 to 44 metres, indicating a reserve of about 60 million tonnes.
