Geochemistry
arundhutighatak@iiserb.ac.in +91 755 269 1373The group's research focuses on the application of radiogenic and non-traditional stable isotope-geochemistry, major-trace element geochemistry, mineralogy, and petrology to different aspects of Earth and environmental sciences. The group develops proxies using isotope ratios of relevant elements to study wide-ranging Earth and environmental process that range across low to high-temperatures as well as modem to geologically ancient times.
Structural Geology, Petroleum Geology
jmallik@iiserb.ac.in +91 755 269 1387The group studies rock deformation and its application in hydrocarbon exploitation, active tectonics and volcanism. The research group is specialized in techniques like Electromagnetic Radiation (EMR), Anisotropy of magnetic susceptibility (AMS), Analogue structural modeling, Reservoir modeling, Seismic interpretation, Fault seal analysis, Fracture analysis and modeling, Pore pressure prediction.
Petrology, Phase Equilibria, Structural Geology
pritams@iiserb.ac.in +91 755 269 1375The group is involved in the understanding of crustal dynamics of Indian subcontinent using structural mapping, igneous -metamorphic petrology, zircon and monazite dating. The group is specialized in geological mapping, quantitative micro -structural analysis, computational phase equilibrium and thermodynamics based geochemical simulation. The group is interested for collaboration with scientists to improve the knowledge related to isotopic dating of zircon.
Economic Geology, Igneous Petrology, Geochemistry
ria@iiserb.ac.in +91 755 269 1393The group is focused on studying magmatic ores of chromite, nickel sulfides, platinum-group elements (PGE) with the aim of understanding the genesis and different styles of emplacement of the ores, and to understand the reasons for their economic concentrations. The magmatic ores are also studied with the aim of using them as tools to trace the supercontinental cycles and crust-mantle evolution of the Earth over the geological time period. We use extensive field geology along with petrography, bulk-rock geochemistry (major element, trace element, PGE), isotope geochemistry (Sm-Nd, Pb-Pb, Rb-Sr), and in situ mineral chemistry (both major and trace elements using EPMA and LA-ICPMS) to achieve our research objectives.
Structural Geology and neotectonics of Fold and Thrust belts and Fault zones
vinee@iiserb.ac.in +91 755 269 1471Our group studies deformation over geological and neotectonic deformation in compressive settings like the Himalayan fold and thrust belt, Kutch Basin and the Shillong Plateau. Our studies include the detailed architecture and kinematics of major fault/shear zones and their associated thrust sheets. We also use deformation microstructures to constrain deformation mechanisms of the rocks in these settings. These studies are also integrated with our Tectonic geomorphology studies to get integrated insights into the deformation, neotectonics and natural hazards in tectonically active regions.
Seismology, Seismic Anisotropy, Receiver Functions, Seismic Attenuation Tomography
aktiwari@iiserb.ac.in +91 755 269 XXXXOur group is interested in understanding the structure, evolution, deformation, and rheology of continental or oceanic crust and upper mantle. The group is particularly curious about the lithospheric structure, deformation, and rheology of the Indian subcontinent and Tibetan region. The group specialises in attenuation analysis of regional seismic phases (Lg, Pg, Pn, and Sn), receiver functions, shear wave splitting of core-refracted (e.g., SKS, SKKS, PKS) and direct-S phases, attenuation tomography, and seismic interferometry.
