Abstract: The boundary between Cambrian and Ordovician in Huolianzhai is determined from typical meleculus and fossils in the newly discoveted Deltyonema flolelliborme-Slaurograptus graptolite belts, integrated with lithology and combination features. On the basis of systematic description of lithoiogy, sedimentary history and environment of lpper Cambrian in this area are analysed.
