Abstract: Yelianchang LFK1 borehole is located in the hanging wall of Hexiwu fault, the depth of it is 249 m and were composed of Middle Pleistocene Yangliuqing Formation, Early Pleistocene Ouzhuang Formation and Holocene deposits.Detailed sporopollen analysis on the Quaternary deposits from LFK1 borehole was conducted and 6 sporopollen-zones were identified.The results show that the vegetation succession and the corresponding climatic variation.According to the features of sporopollen assemblages and combined with dating and drilling data, we determine that Sporopollen-zone I is Middle Pleistocene, Sporopollen-zones II, III, IV and V are Early Pleistocene, Sporopollen-zone VI is Holocene deposits.
