Abstract

MAGSAT vertical component (Z-component) of crustal anomalies are correlated for the first time with major geological and tectonic boundaries/features of the Indian subcontinent. A prominent ‘low’ is consistently observed on all the profiles centred between 19° and 23° latitudes over the broad Peninsular ‘high’. The other conspicuous ‘low’ indicated from the present work is confined to the region above Sarda depression (29° N to 31° N) in the foothills of Himalayas. Interesting magnetic signatures are identified over the Narmada-Son rift and Godavari graben.
