Fold-thrust-belt structure of the Proterozoic Eastern Ghats Mobile Belt: A proposed correlation between India and Antarctica in Gondwana
The Proterozoic Eastern Ghats Mobile Belt along the east coast of India shares a thrusted lower contact with the surrounding cratons. The thrust, known as the Terrane Boundary Shear Zone, is associated with two large lateral ramps resulting in a curved outline on the northwestern corner of the mobil...
