The Neoarchaean (2.8–2.5 Ga) era in the earth’s history witnessed significant crustal growth related to the amalgamation and dispersion of ancient continents. The processes leading to the formation and destruction of the ... -
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 ... -
Stable isotope and biogeochemical study of arsenic contamination in shallow groundwater at seasonal time intervals from West Bengal (Nadia district)
