Igneous Petrology, Geochemistry, Mineralogy with special reference to kimberlites, lamproites and lamprophyres; Process Mineralogy; EPMA of minerals. My research interest primarily involves the petrogenetic aspects of small-volume potassic to highly potassic rocks such as kimberlites, lamproites, lamprophyres and their entrained xenoliths (including diamond).I particularly am interested in their role in unraveling the large-scale geodynamic processes of the Indian shield including the composition and evolution of its sub-continental lithospheric mantle, origin and original spatial extent of the Mesozoic Large Igneous Provinces ( Eg : Deccan Flood basalts, Rajmahal basalts) and the Proterozoic sedimentary basins ( Eg : Purana basins). My work involves field as well as laboratory components with integration of data from petrography, mineral chemistry, geochemistry, stable and unstable isotope systematics and geophysics (paleomagnetism and petrophysics). My current research interests also include the study of mafic dykes and dyke swarms, alkaline rocks, carbonatites and mass-extinctions associated with the Cretaceous-Tertiary (65Ma) boundary.
