摘要
Storm deposit is a kind of special event deposit, and reveals palaeogeography and palaeoclimatology changes of certain period in certain region. Through the palaeogeography research and fine strata division, the evidence and characteristic of storm deposit of shallow lake in lower submember of member 2 of Shahejie Formation of Wennan-Liuzhuang Area, Dongpu Depression were discussed, and the sedimentary model of storm deposit was summarized. The results showed that deposition sequence of lake basin was mainly controlled by climate, so the frequent climate change resulted in the wide distribution and multi-period development of storm deposit. The sedimentary models of storm deposit mainly included class I and class II.
