| 摘 要： | 华北寒武系标准剖面分布在济南市长清区张夏镇和崮山镇,该剖面寒武纪地层发育,出露良好,三叶虫等古生物化石保存完好,笔者根据微体古生物牙形石的种属及其在地层中的分布序列,建立了上寒武统6个牙形石生物带,并根据牙形石"Cordylodus lindstromi"的首现,准确地确定了寒武系与奥陶系的界线;对寒武系长山阶的碳氧同位素曲线特征进行了分析,并把长山阶底部的碳同位素曲线与我国华南及哈萨克斯坦等国寒武系芙蓉统底部的碳同位素进行了对比,建立了华北寒武系与国内以及国外寒武系的对比关系。 |
| 关 键 词： | 华北 上寒武统 标准剖面 牙形石 张夏镇 崮山镇 山东 |

| Abstract: | Standard profiles in Cambrian distribute in Zhangxia and Gushan town in Changqing district of Jinan city.Cambrian strata developed very well in this area with good crop,and Palaeobio-fossils of trilobite were preserved well.This area is standard profile for carrying out studies,such as lithostratigraphy,biostratigraphy,chronostratigraphy and chemo-stratigraphy.According to micropaleontological conodont types and its distribution sequences in strata,6 condont biographic belts in upper part of Cambrian are set up.According to first occurrence of "Cordylodus lindstromi",boundary of Cambrian and Ordovician is determined correctly.Characteristics of carbon-oxygen isotopic curve of Changhsingian in Cambrian is analyzed in this paper.Carbon isotopic curves in lower part of Changshangian and its in lower part of Furong series of Cambrian in Kazakhstan are contrasted,and contrast relationship between Cambrian in Huabei area and Cambrian abroad is set up. |
| Keywords: | Upper part of Cambrian Huabei area standard profile condont Zhangxia town Gushan town Shandong province |
