My present research revolves around metamorphic petrology in conjunction with thermodynamics to decipher the tectonic architecture and metamorphic evolution of the continental orogenic belts and their spatio-temporal connection with the supercontinent cycles. I use microstructures, textural reactions, geochemical characteristics, and advanced geochronology of selected metamorphic minerals by using latest softwares and instrumental techniques in geosciences (PTCALC, TWQ, QBASIC, Perple_X, MATLAB, THERMOCALC along with XRF, LA-ICPMS, IRMS etc.) to decode their parageneses, origin and tectonic discriminations. Metamorphic processes are a bit dynamic in nature and in a state of non-equilibrium conditions. It requires sizable amount of time and energy for them to equilibrate and stable over time with minimum Gibb’s free energy. Energy involving physico-chemical variables, viz. pressure and temperature with activity compositions in alignment of time tells us the path experienced by a metamorphic rock that is set of all P-T conditions from the origin to cessation of equilibrium kinetics of minerals to achieve its peak P-T equilibrium conditions during its whole metamorphic history. I use multi-metamorphic proxies, viz. geochronology, conventional geothermobarometry linked with High-resolution P-T path trajectories and isochemical phase section modellings to unravel the time of peak metamorphic conditions and their spatio-temporal connection with the supercontinent amalgamations and fragmentations. I further stretch my area of research on planetary research with special emphasis on the geochemistry and metamorphism of meteorites and their components to know their crustal evolution and mantle dynamics.
