摘要
通过实测莱芜黄羊山晚寒武世地层剖面,利用牙形石确定了寒武系与奥陶系的界线;对长山阶的碳氧同位素曲线特征进行了分析,并与我国华南及哈萨克斯坦等国的寒武系芙蓉统底部的碳同位素曲线进行对比,建立了莱芜地区上寒武统与华南以及国外上寒武统的对比关系。
Through measured late Cambrian stratigraphic profile and by using conodonts, Cambrian and Ordovician boundary are determined in this paper, the characteristics of carbon and oxygen isotope curve in Sankai period is analyzed, and compared with carbon isotope curve at the bottom of Cambrian Furong group in southern China and Kazakhstan. On these basis, the comparison relation between upper Cambrian in South China and abroad is estab- lished.
