| 摘 要： | 通过对明祖山剖面的岩石地层、年代地层、生物地层的综合研究及区域地层对比 ,得出以下结论 :①明祖山剖面可划分为五个牙形石带 ,寒武—奥陶系界线位于Cordylodusproavus带与Utahconusbeimadaoensis Monocostodussevierensis带之间 ;②通过区域地层对比 ,寒武—奥陶系分界在青州地区已位于炒米店组之内部 ,而且整个两河口阶全部位于炒米店组上部

| Abstract: | Through stratigraphic studies, Mingzu mountain profiles in Qingzhou area, Shandong province can be divided into five conodont belts. The contact line of Cambrian and Ordovician locates between Cordylodus proavus belt and Litacaonus benumadaoenis-Monocotodus severensis belt. Through contrast of regional strata, it is regarded that the contact line lies inside the Chaomidian formation, and the whole Lianghekou stage matches the upper part of Chaomidian formation. |
