Geological mapping of Jharia Coalfield, India using GRACE EGM2008 gravity data: a vertical derivative approach

Geocarto International, 2014
High-resolution satellite gravity data of gravity recovery and climate experiment (GRACE) generated by Earth Gravity Model-2008 (EGM2008) have been utilised for geological mapping of the Jharia coalfield. The generated GRACE EGM2008 classical gravity data have been processed for estimation of gravity anomaly map.
