Paleoclimatic implications of organic carbon isotope and environmental evolution in Jianghan plain since last glacial maximum

Regarded as a sensitive indicator to paleoclimatic changes, the organic carbon isotope (δ¹³Corg) in lake is widely used to reflect paleoclimatic condition and paleoenvironmental evolution. By combining analysis of other proxies, this paper is to the implications of δ¹³Corg in Jianghan Plain of warm and moist climate setting. The values of δ¹³Corg in Jianghan Plain can indicate the varieties of rainfall. Further conclusions can be made based on the δ¹³Corg values together with other indicators: 4 stages of paleoclimatic change can be recognized in Jianghan Plain since last glacial maximum.
