Late Palaeozoic Sporopollen Assemblages and the Low Limit of Upper Permian in the Southern North China
Based on the sporopollen fossils data in Well Zhoucan 13 and other wells in the southern North China,it establishes 3 sporopollen assemblages and 5 subassemblages. Their geological eras are discussed. The interface of .the Upper and Lower Permian is defined.
