英文摘要	The Quaternary fluvial sequences of the Belan river in north-central India preserves the signature of prehistoric human settlement from Paleolithic to Neolithic interval. The settlement history in the Belan valley has been attributed to be driven by climatic fluctuations, although quantitative climate data from the valley is lacking. For the first time, we have analysed oxygen and carbon isotopes in soil carbonates (δ18OSC and δ13CSC) and hydrogen and carbon isotopes in n-alkane of paleosol (δDC29 and δ13CC29) from chronologically well-constrained six archaeological sites to understand the climate-cultural relationship. The chronological sequences were refined by Bayesian statistics using ChronoModel 1.5. The δDC29 and δ18OSC values, proxies for rainfall, indicate two phases of isotopic depletion during ∼100 to 75 ka and ∼18 to 3 ka implying intensification of monsoon. During ∼75 to 25 ka, the δDC29 and δ18OSC values show fluctuation in the monsoonal rainfall. Higher δDC29 and δ18OSC values during ∼25 to 18 ka suggest an arid environment, which corresponds to the Last Glacial Maximum (LGM). The present study suggests that climate was the driving force for fluvial incision and aggradation at a regional scale during ∼100 to 3 ka. The δ13CC29 and δ13CSC values suggest that the C4 plants dominated in a mixed C3-C4 environment between ∼75 and 25 ka. The abundance of C4 plants sharply decreased during the early-Holocene. Comparison between climatic conditions and the temporal variation in the number of archaeological sites suggest climate-driven shifts in population density or local migration of prehistoric humans during the Middle Paleolithic to Early Neolithic phase. © 2019 Elsevier Ltd
