Reconstruction of temperature for Cenozoic and Proterozoic Ocean water using clumped isotope thermometry
Clumped isotope thermometry is a novel tool which is used for the determination of formation temperature for carbonates of diverse origin and understanding different marine and terrestrial processes. The primary interest ...
A geochemical and Nd-Sr-Ca isotopic study of silicate weathering, crustal recycling and petrogenesis of carbonatites
Weathering of silicate rocks releases cations and anions which are transported to the oceans by
rivers where calcium carbonate precipitates from the seawater. This process results in the net
consumption of atmospheric ...
Improved laboratory and computational models for thermal core–mantle interaction
The Earth's magnetic field is generated by thermochemical convection within its
fluid
outer core. The near-stationary high-latitude magnetic
flux concentrations in the present
day field indicate that convective ...
Understanding the dynamics and evolution of cratons
The earth is the only rocky planet in the solar system that exhibits plate tectonics. One of the basic tenets of plate-tectonics is that it recycles the lithosphere within a few hundred million years. No oceanic lithosphere, ...
Stable isotope and biogeochemical study of arsenic contamination in shallow groundwater at seasonal time intervals from West Bengal (Nadia district)
Seasonal monitoring of groundwater is essential to ascertain safe water for the population and
ecosystem for drinking, irrigation, domestic purposes and to keep track of groundwater
quality with natural (climate change ...
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 ...
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 ...
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 ...
A Geochemical and Sr, Ca, Mg, Li isotopic study of the Godavari River draining the Deccan basalts
Chemical weathering of continental silicate rocks releases cations and anions which are eventually precipitated as carbonates on the ocean floor. This entire process transfers carbon from the atmosphere to the oceans leading ...
