【Abstract】 The Ordos basin experienced a long period of continental deposition during Palaeozoic and therefore,is an ideal place for research of sequence stratigraphy of continental deposits.Through detailed study of stratigraphic correlation and based on the theories of modern sedimentology and sequence stratgraphy,a stratigraphic division was established.In Palaeozoic continental area,the delta deposits ad other lake basin fillings can be classified into 21 sequences which can be subdivided into 5 ultrasequences,and these squences respond well to the evolution of Ordos basin from Shanxi stage of early Permian to Shiqianfeng stage of late Permian.更多还原
