Started teaching as an assistant professor in the Central University of South Bihar from the year 2020 onwards in the department of Geology under the Earth, Biological and Environmental Sciences CUSB, Gaya.
Teaches Igneous Petrology & Geochemistry of mafic/acidic rocks include geochemical data interpretation and analyses in Department of Geology as a guest faculty in the University of Delhi. Postdoctoral experience in the title “Geochemical and isotopic studies of mafic rocks from Nagaland-Manipur Ophiolite Belts: Constraints on magmatic evolution and tectonism in North-Eastern India” in the Department of Geology, University of Delhi.
The various tectonic activities since the Archean in the CITZ caused rifting, volcanism, compression, addition of magmatic material from the lower crust/mantle, and partial melting of the older continental crust. The collisional suture between the Bundelkhand craton (north of SNNF) and the Bastar craton (south of CIS) is marked by the high‐pressure granulites of the Ramkona–Katangi and Nagpur–Bhandara–Balaghhat belts, shown as black patches in the Tirodi basement gneiss along the GTSZ and CIS. The Khairagarh volcano‐sedimentary sequence is exposed along the Kotri–Dongargarh Belt towards the north‐eastern part of the Bastar Craton. This sequence is exposed south of the Central Indian Shear (CIS) and east of the Sakoli Group rocks. The Khairagarh volcanic sequence is represented by low‐Ti, intermediate‐Ti and high‐Ti basalt–basaltic andesite series that probably represent varying degrees of partial melting of an enriched mantle source, thus they appear to be consanguineous. These rocks are associated with a sequence of high magnesium andesitic (HMA) rocks that follow a separate evolutionary trend, thus they appear not to be related to the basalt–basaltic andesite sequence. The presence of the two contrasting sequences probably indicates generation in a hot Andean‐type subduction zone for the HMA, and Andean‐type back‐arc rifting for the basalt–basaltic andesite samples. The possibility of a relatively thick crust around 3.6 Ga in the Bastar Craton and the Amgaon Gneissic Complex, basement for the Khairagarh–Sakoli sequence, probably indicates that it was part of the Supercontinent Ur. The mantle extraction age of about 2.9 to 2.5 Ga, based on the Nd‐model ages for the Khairagarh–Sakoli sequence, probably indicate that this part of the Central Indian Shield became part of the Supercontinent Columbia subsequently.
