Presented to Dr. Abhishek Saha

Citation

Dr. Abhishek Saha, Senior Scientist, National Institute of Oceanography, Goa; is awarded the coveted late Dr. Shrichandra Srivastava Gold Medal-2021 for excellent contribution in geochemistry. Dr. Abhishek Saha, 38 years, acquired Ph. D. in Geology on Mafic-Ultramafic-Alkaline Complex of Karbi-Anglong, Assam from Calcutta University in 2012. Afterwards, he served in Indian Institute of Science as Research Fellow.  He was DST inspired faculty at NGRI, Hyderabad in 2014-15 and later joined as Scientist in NIO, Goa.

He was a principal investigator in exploration for polymetallic nodules in oceanic floor. He spearheaded project on geochemical studies of volcanic rocks in Andaman Basin and tectonic processes along subduction zone in Indian Ocean elaborating the inter-relation of subduction zone with geochemical signatures of lithology. He has wide experience in oceanic research through scientific cruises in Indian Ocean.

He is Associate Fellow of Andhra Pradesh Academy of Sciences and reviewer of number of International Geoscience Journals like Precambrian Research, Journal of Asian Earth Science and Journal of Applied Geochemistry. His contribution in geochemical evolution of PGE and Chromite occurrences in Nagaland, Geochemical fingerprints of crustal mantle section of  Ophiolite in Nagaland,  magma genesis in Andaman Volcanic Arc and geochemical characters of submarine rhyolite plumes, highlight the geochemistry of rock types and mineralization along subduction zones. Besides having implications on earth processes, this research leads to understanding of genesis of rare mineralization in contact zones.

The Gondwana Geological Society, Nagpur feels privileged to honour his contribution in geochemical research on subduction zone, tectonism and genesis of mineralization thereof.
