The Geochemistry Division is involved in various research programs related to the Earth's crust and interior. The R & D activities of our group are focused to better understand the geodynamic evolution of the Earth's crust, potentiality, and the genesis of ore deposits across the country. Our approach towards addressing these complex scientific problems involves multi-disciplinary studies that include field geology, structural analysis, petrography, bulk rock geochemistry, mineral geochronology (U-Pb zircon, and Pb-Pb baddeleyite), and radiogenic isotopes. The group contributed immensely in the past four decades towards understanding the evolution of Archean continental crust from different cratonic blocks of India, the origin of early life, gold and iron mineralization, and Archean depositional environments. The group also actively participated in assessing the environmental impact and health hazards of contaminants in various parts of India. The Geochemistry Division has state-of-the-art analytical facilities and has long-standing effective collaborations with reputed national and international research groups.
