A geochemical and Ca-Sr-Nd isotopic study of glacial diamictites, loess and saprolites to understand crustal growth and silicate weathering

Haldar, Utpalendu

Earth is the only rocky planet in the Solar System with a compositionally evolved (felsic) continental crust. This incompatible element enriched layer is dominantly formed by extraction of melt from the upper mantle leading ...
Late Cenozoic climate reconstruction from the Northern Indian Ocean using foraminiferal clumped isotope thermometry and stable isotope technique

Sakthivel, Thamizharasan

The Late Cenozoic era (23.03 million years ago to the present) offers a critical time window to examine the role of greenhouse gases, notably CO2 (ranging between 910 ppm and 180 ppm), in the operation of Earth's system ...
Quantification of Air-Sea CO2 exchange from the Southern Ocean during last deglaciation

Chanakya, Satya I V

Glacial and interglacial cycles are natural, rhythmic patterns of global climate. These cycles are primarily driven by variations in solar forcing, commonly known as Milankovitch cycles. The solar forcing includes eccentricity ...
