Research Theme

The identified research themes of the group are carried out in coordinated studies along some geotransects in NW Himalaya and some similar integrated geotranset is also initiated in the Eastern Himalayan Syntaxis. The studies undertaken by different group scientists in different project mode are listed under the heading Current Ongoing Projects. Some of the broad research activities of the group are as follows:

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..
The reconstruction of the P-T-t path and exhumation history of the High Himalayan Crystallines and associated leucogranites are of great importance as this will help us to understand the evolution of metamorphic rocks / processes in one of the youngest orogenic belt and to understand mechanism / process that led to inverted metamorphism in the Himalaya. Such studies are taken up in Uttarakhand Himalaya.
Comparison and crustal evolution of Gneissic domes from the Tso-Morari and Leo-Pargial regions is also being carried out, along with UHP metamorphic studies in Tso-Morari region. Also, magmatic and metamorphic studies in Ladakh are in progress.
Geochemical studies of Proterozoic sediments from Uttarakhand and the geochemical and isotopic studies of source rock and head waters of Indus and Ganga are also studied.
Investigate genesis and evolution of metal sulphide mineralization and the nonmetallic industrial minerals such as talc, magnesite and graphite present in the crystalline and the sedimentary successions of the Lesser Himalayan geotectonic zone in Kumaun region, and also to look for new occurrence of ore minerals in Himalaya.
Physiochemical parameters controlling the behavior of elements and its distribution during natural geological processes on the earth’s surface is now believed to be far from random. The presence of elements in the natural environment is generally governed by the spatial distribution of geological formations and soils derived from various source rocks. However, their abundance are locally modified to a large extent and regionally to some extent by Eh-pH conditions, industrial or man made pollutions and factors related to urbanisation and human interference with the natural processes. In this context, the soil and stream sediments from Uttarakhand and Himachal Pradesh are studied in detail for the sources, dispersion and distribution of elements in the environment.
