    The Precambrian rocks of India have been classified into two systems, namely the Dharwar system and the Archaean system (gneiss and schists). The Dharwar System. The rocks of the Dharwar system are mainly sedimentary in origin, [8] and occur in narrow elongated synclines resting on the gneisses found in Bellary district, Mysore and the Aravalis ...

    [7] [8] [9] The rock units that make up the Indian Plate vary dramatically along the length of the basin, changing from Proterozoic Mobile Belt rocks, to Archean Craton, and Proterozoic Vindhyan Supergroup sedimentary rocks. [10] These Indian Plate rock units extend under the foreland basin and have been correlated to a series of depressions ...
