The understanding of Proterozoic crust such as that of Lesser Himalaya is one of the challenges, the group is aiming yet. The crystallines including granites and host metamorphics of the Kumaun Himalaya are under study to understand the crustal evolution and exhumation history. Since there is considerable variation within these crystallines, it is aimed to recognize variation in these crystallines, their petrogenesis, emplacement and evolution. The geochemical and petrogenetic studies of basic and metabasic rocks of Lesser Himalayan sequence from Arunachal Himalaya of North-East are also underway. |
