Application of Remote Sensing, Magnetic and VLF (EM) Techniques for Discovery of Lamproites near Ramadugu and Vattikod area, NW margin of the Cuddapah Basin, Eastern Dharwar Craton

摘要

Semi detailed 2-D and (precision) geophysical surveys were carried out in the Ramadugu study areas of north western part of Cuddapah basin in Telangana State, India. Qualitative analysis of total magnetic components brought out geological contacts, seven faults (F1 to F7) and four tectonically disturbed zones (A, B, C & D), the surface morphology and structural configuration were obtained from Land Sat 8 ETM Satellite image of the Ramadugu study area of Nalgonda District (longitude 79°5? to 79°25?and Latitudes 16°42? to 16°58?), From observed surface correlation of reported lamproites occurrences, characterized by contact between dykes and granitic rocks, lineaments/faults peripherals of domal structures, circular to oval shaped structural features, which could have acted as potential sites for lamproites.........
