Professor, Centre for Earth Sciences, IISc (2008- Present)

The evolution and crustal growth processes on the Earth during the late Archaean period (~2.5Ga) was my research focus after joining IISc, especially during the current review period of July 2014 to July 2020. The Archean-Proterozoic boundary represents a significant transitional period in Earth evolution, when there was a sudden rise in the amount of atmospheric oxygen (Great Oxidation Event) and the birth of present-day plate tectonics. Globally, ~2.5 Ga-old terranes are rarely preserved, because this period marks a sudden drop in the volume of newly formed crust, which in turn represents the beginning of active plate tectonics. Moreover, Archaean arcs and continents worldwide are unusually rich in mineral resources; accordingly, it is imperative to understand their genesis and evolution. 

Several fragments of the Gondwana Supercontinent, such as India, Africa, Sri Lanka, and East Antarctica, consist of Late Archaean crust. Among these, southern India is particularly important as it contains several ~2.5 Ga crustal units that were metamorphosed to a very high-grade at ~2.4 Ga.

Dr. Sajeev Krishnan, Team Leader

 

I was awarded the Monbusho (Monbukagakusho) Scholarship by the Japanese Government in 1999 for carrying out my PhD research at Okayama University. Post-doctoral research included about one year of experience in the Chonbuk National University (South Korea) Postdoctoral Fellowship in 2004 and two years of JSPS Postdoctoral Fellowship by the Japanese Government in 2005. Followed by that, I worked as a research professor in Brain Korea 21 project at Yonsei University, South Korea, from January 2007 to July 2008, before joining the Indian Institute of Science as Assistant Professor in July 2008. 

                             However, very few regional-scale studies were available from these regions up to 2008. Hence the objectives of my research group mainly focused on topics such as Delineation of the chronology and mineral evolution connected with geological events and processes during the late Archaean period and understanding the genesis and evolution of Archaean mineral resources .
