Dr. Sharma holds the position of Assistant professor in the Department of Geology, Ravenshaw University. He has completed his doctorate in the year 2020 from Banaras Hindu University, Varanasi (UP). His doctorate research work mainly focuses on the petrogenesis and geochemical aspects of ultramafic rocks from the Wajrakarur kimberlite field and Gurramkonda area of Eastern Dharwar Craton, Southern India and their geodynamic implications. Further, he carried out his post-doctoral research work at physical Research Laboratory, Ahmedabad from 22 March 2021 to 28 February 2022. During the course of his research he has published a number of articles in reputed peer reviewed SCI journals.

  • I am basically an igneous petrologist and geochemist and my research specially focuses on the petrogenetic aspects of magmatic rocks with a special interest on small volume potassic to highly potassic rocks such as kimberlites, lamproites, lamprophyres, their entrained xenoliths and ultramafic rocks such as pyroxenites and peridotites and in understanding the nature of the mantle and its evolution. I use mineralogy, geochemistry and isotopic signatures of magmatic rocks as a proxy to probe into the earth’s mantle, infer their tectonic settings, source region characteristics and unravel the large-scale geodynamic processes of Indian shield including the composition and secular evolution of its sub-continental lithospheric mantle. I also have an interest in deciphering the complex processes occurring within magmatic chambers formed through pooling of magma along its path of cooling to its final solidification.
