Thesis Title: Potentials of isotopic compositions of Molluscs from Ganga plains for paleoclimate reconstruction.

Abstract: 

 

 

 

 

Indo-Gangetic plains, mainly drained by the Ganges/Yamuna system, are potential archives for the proxies of the past climatic conditions. This area has experienced large fluctuations in discharge related to the variations in Southwest monsoon strength. Therefore, changes in the monsoon strength and precipitation, regional distribution and seasonality will affect the entire Indo-Gangetic plains. Paleoclimatic records from Ganga plains (continental) compared to marine ones are less understood. Lake environments serve as high-resolution archives of paleoenvironmental conditions. Stable carbon (δ13C) and oxygen (δ18O) isotope compositions of shells and soil carbonates reflect the plant source of the carbon or the prevailing vegetation (C3 or C4) in the area and precipitation condition (temperature), respectively. Carbon and oxygen isotopic compositions of molluscs, land snails, carbonates as well as lake sediments will be used as proxy to infer paleoprecipitation and paleovegetation conditions in the Ganga plains.
