Description :
The intracratonic Gondwana basins of peninsular India occur in long, narrow, well-defined belts on the Precambrian platform, corresponding to rivervalleys of Damodar-Son, Mahanadi and Godavari. The basins are half grabens or grabens, with margin faults near maximum sediment thickness. These faults, indicative of regional tension, played a dominant role in the basins'evolution. The terrestrial clastics and coal beds in the Damodar-Son and Satpura basins are cut by ultrabasic and basic dykes and sills| volcanic activity during the Upper Jurassic is also indicated near Rajmahal. Igneous intrusives are conspicuously absent in the Godavari and Mahanadi Valleys.
