Geoelectric structure of the Dharwar Craton from magnetotelluric studies: Archean suture identified along the Chitradurga-Gadag schist belt
The thrust proposed here pre-dates the formation of these schists, which occurred during the Late Archean (2600 Ma). The accretionary wedge of the thrust and the depressed part of the West Dharwar ...
