Abstract: Traditional gravity data processing involves terrain and Bouguer corrections with uniform density. However, inclusion of variable densities honouring surface geology in such corrections is a long-felt need. This matter assumes fundamental importance for gravity data acquired over high relief. So, improved Bouguer and terrain correction scheme is proposed and its utility is demonstrated on a gravity profile along Mahe-Sumdo-Tso Morari of Ladakh Himalaya. A maximum difference of about 50-70 mGal in the final Bouguer anomaly is observed between data processed through normal procedure with uniform Bouguer density (= 2.67 g/cm3) and those proposed with variable density. This underlines the importance of the proposed scheme.
