Abstract
Pedogenic carbonates, widespread in paleosols throughout the geological ages, have been widely used to infer climatic conditions and vegetation type during their formation. They are ubiquitous and widespread in the Late Quaternary loess–paleosol sequence of the Kashmir Valley, mostly in the form of carbonate nodules. In the present study, pedogenic carbonates are studied to analyze trends in the stable isotopic composition of carbonate nodules across three well-developed loess–paleosol sections in the Kashmir Valley. The stable carbon isotopic (δ 13 C) analysis reveals a gradual increase of the C 4 vegetation towards the top of the sections. The development of C 4 plant biomass towards the top of sections possibly reflects water stress and/or reduced atmospheric pCO 2 and incr…
