Abstract AMS-14C dating provides a new way in archaeology studies because of its high precision and speed and applicability in micro-sample dating. It is widely used in late Quaternary and Neolithic archaeological research. Based on AMS-14C dating of loess-paleosol sequence of the Xinjie profile at Lantian County of Shaanxi Province, the archaeological chronology of this sequence was obtained by using Bayesian method. Combining the stratigraphic sequence, magnetic susceptibility and pollen analysis, we got the conclusion that the weather was dry and cold during Malan loess period, and warm in Holocene, humid and warm in Yangshao period, dry and warm in Longshan period, dry and cold in recent Loess forming period.
