Formation of clinohumite (instead of brucite) at the expense of forsterite due to infiltration of F- and Ti-bearing extremely H2O-rich fluids (XCO2 < 0.03), at ~5–6 kbar pressure and ~650–700 °C temperature, in dolomitic marbles from the Makrohar Granulite Belt, Central India: Evidence for Ti mobility during regional metamorphism (Karmakar 2021)

An awe inspiring experience for me, getting to share the stage with such eminent dignitaries... I (one of the Jt. Convener) was asked to share a few words on behalf of the young organisers!

Formation of clinopyroxene-ilmenite at the expense of garnet-titanite, along a steeply decompressive retrograde P-T path (from ~13 to ~7 kbar, at ~800 °C), in the presence of partial melts, from a mafic granulite, East Indian Shield. The study demonstrates that relative to Fe, Mg, and Ca, Ti was less mobile and that the mobility of Ti was restricted within the confines of titanite being replaced by the clinopyroxene-ilmenite symplectite.

A mention in the society news in Elements Magazine, on receiving the Paul Ramdohr Prise (by the German Mineralogical Society - DMG) for the best oral presentation, at the first European Mineralogical Conference-2012 in Frankfirt, Germany ... in the first year of my PhD
Formation of euhedral corundum (ruby) through vapour present incongruent melting of the highly calcic plagioclase (An>95) during UHT)metamorphism (T ≥ 1000 °C, P ≥ 9 kbar), its subsequent breakdown to spinel during HP decompression (11 ± 2 kbar, 750 ± 50 °C), and spatially restricted development of sapphirine due to Mg-Si metasomatism during low-T fluid infliltration at the tail end of the decompression, in an anorthosite from Sittampundi, South India (Karmakar et. al. 2017)
Formation of euhedral microscopic corundum through desilification and decalcification of anorthite (An95–99) , during recrystallization of the anorthite lenses at high pressure (HP) metamorphism (~800 °C, 8–11 kbar) in an anorthosite from Ayyarmalai-Manavadi, South India (Karmakar et. al. 2020)
