Interpretation of gravity anomalies of parts of deccan trap regions of peninsular india

Abstract

The present research work deals with the interpretation of some newlineprominent gravity anomalies observed in Deccan trap covered regions of newlineIndian peninsula. The gravity anomalies used in this thesis are extracted from newlinethe Gravity Map of India (1:5000000) published by NGRI-GSI in 2006. newlineGeological Survey of India (GSI), National Geophysical Research Institute newline(NGRI), Oil and Natural Gas Corporation Limited (ONGC), Survey of India newline(SOI) and Oil India Limited (OIL) under joint collaborative project revised newlineGravity Map of India (1:5000000) published in 1975. Basic gravity data newlinecollected over 1,43,786 stations by these organizations during the last two newlinedecades was synthesized and generated a revised Gravity map Series. The newlineseries comprises Free-air Gravity map of India, Bouguer Gravity Map of newlineIndia, Bouguer Gravity superposed over Geological Map of India and Gravity newlineImage Map of India. Bouguer gravity map superposed over Geological map of newlineIndia covering the area between 16° N and 22° N latitudes and 73° E and 80° newlineE longitudes has been used for extraction of gravity anomalies in the present newlinestudy. newline
