The objective of the study was to analyze the subsurface geological structures as well as the litho-contacts of the study area. An effort was made to analyze the Magnetic anomalies (TMI) as well as the Remote Sensing data for the eastern Dharwar craton to understand the setting of geological structures in the region. The analysis was placed according to the methods of Proton procession magnetometer surveys, Data Interpretations and filtering as well as the Remote Sensing skills. The magnetic susceptibility data understandings gave a considerable response towards the subsurface geology thereby indicating the moderate seismicity in Southern India by delineating underground faults. The exploration of the collected field data verified the assumptions of remote sensing towards the seismicity of the area. The study demonstrates the dominancy of hornblende-biotite-genesis, charnokite formation, and Epidotite-hornblendegneiss and small intrusive granitic/gneissic granites in the Tindivanum region of Tamilnadu. The significance of Geophysical ground magnetic surveys and effective processes of De-convolutions, Analytical signals, and Reduction to pole, Hilbert transformations etc. evidenced the efficiency of Ground magnetic and satellite data in structural variations especially for locating faults. The Geophysical ground magnetic surveys have varied its results from interpretations made to satellite magnetic data by a large extent. The study also emphasise the need of incorporated approaches of geophysics and remote sensing for seismic analysis and can be very handful in the modern science and technology.
