Structural Analysis of Airborne Radiometric data for Identification of Kimberlites in Parts of Eastern Dharwar Craton

Airborne radiometric data, covering 1933 Sq. km of Mahabubnagar and Gulbarga districts of Telangana and Karnataka states in the Eastern Dharwar craton, India to evaluate the structural configuration of the region. Air-borne radiometric data has been analyzed to identify the surface anomalies pertaining to the lithological characteristics and several lineaments trending in three major directions NE-SW, NW-SE and E-W were well matched with the Aster & Landsat 8 and Airborne magnetic structures, has been integrated and presented in the GIS environment. . The Zones of intersection of these structural trends which could have acted as potential sites for kimberlites emplacement were accordingly delineated at 21 locations (AA1, BB1 to BB5, CC1 to CC2, DD1 to DD2, EE1, FF1, GG1 to GG3, HH1 to HH3 and II1).
