Paleoproterozoic granitoids are important rock types all along the Lesser Himalayan belt and provide key constraints for understanding the evolution of the northern Indian continental margin and its position within the Columbia supercontinent assembly. The Paleoproterozoic Ramgarh mylonitic granitoids of the Baijnath klippe in the Inner Kumaun Lesser Himalayan Sequence show pervasive mylonitization, with augen‐shaped porphyroc...

The Cenozoic Himalayan orogeny resulted from the continental collision between the Tibetan block and the northern Indian Precambrian shield. The latter, replete with evidence of Columbian supercontinent assembly, likely comprised the north Indian continental margin that was reworked mechanically and thermally during the Himalayan orogeny, and still survives as Precambrian vestiges in the Himalaya. Parts of this Paleoproterozoi...
