Satellite geoidal data over the Elan Bank region in Antarctica could be demarcated with the surroundings and confirmed as continental lithosphere. It has been obser­ved that the satellite geoidal map can well demarcate the continental margin region near the Indian coastal region using high-resolution geoid/gravity data. This also helps determine the nature of the lithospheric plate over the Elan Bank. A large portion of land got detached from the Indian plate during the transition processes between the continental and oceanic crust that were originally created by rifting. Satellite geoidal mapping is a comparatively new technique for crust delineation, offshore exploration and tectonics-related studies.

Satellite geoidal data over the Elan Bank region in Antarctica could be demarcated with the surroundings and confirmed as continental lithosphere. It has been obser­ved that the satellite geoidal map can well demarcate the continental margin region near the Indian coastal region using high-resolution geoid/gravity data. This also helps determine the nature of the lithospheric plate over the Elan Bank. A large portion of land got detached from the Indian plate during the transition processes between the continental and oceanic crust that were originally created by rifting. Satellite geoidal mapping is a comparatively new technique for crust delineation, offshore exploration and tectonics-related studies.
