A 200 cm long successive loess core was firstly obtained by digging a well at Caijiazui section in the Xifeng located in central loess Plateau in China. According to ¹⁴C-AMS dating results and the grain size model, the reliable chronologic framework of Xifeng section over the past 20 ka was derived in turn. Multi-proxy analysis on the magnetic susceptibility, grey scale and grain size clearly reveal the typical climatic episodes. It suggests the potential ability of Xifeng loess section for recording the abrupt climatic variations on the small scale.
