Assessing the potential of stable calcium isotope ratios for paleotemperature reconstruction from studies of laboratory-precipitated inorganic carbonates and modern corals, fish otoliths and foraminifera
Determining paleo-seawater composition and temperature is critical for reconstructing Earth’s surface conditions through time and has major implications for understanding the origin and evolution of life on Earth. ... -
Geochemical and isotopic study of the Lonar and Dhala impact craters and jarosites from Kutch, India as analogues to understand planetary surface processes
Impact cratering and aqueous alteration are two important processes that have modified the Earth’s surface over time and better understanding of these processes on Earth allow us to understand the surface evolution of other ... -
A geochemical, Nd-Sr, and stable Ca isotopic study of siliciclastic and chemical sedimentary rocks, volcanic tuffs, and authigenic glauconites from Proterozoic sedimentary basins of India
The Archean-Proterozoic transition is marked by globally synchronous changes in tectonothermal and climatic patterns along with development of widespread epicontinental seas, with extensive shelf-sedimentation. The Indian ... -
Investigating the role of mantle convection in affecting surface deformation and topography in the Indian plate and the India-Eurasia collision zone
The India-Eurasia collision zone has been a subject of various studies that have tried to explain the forces behind the high elevation and large scale continental deformation in this region. However, the relative contribution ... -
Seasonal Isotopic Variability and Major Ion Chemistry of the Cauvery River Basin, Peninsular India
Surface water and groundwater interactions are inherently complex because they occur across a range of spatial and temporal scales. This thesis envisages to improve our understanding of surface water and groundwater in ...
