| 摘 要： | 三峡地区覃家庙群以一套缺乏化石的薄层白云岩沉积为特征。新近在湖北兴山古洞口剖面覃家庙群底部发现Kaotaia gedongensis Yuan & Zhao,Kunmingaspis yunnanensis Chang,Chittidilla sp.等三叶虫。依据三叶虫生物地层学对比结果,结合研究剖面与覃家庙群标准剖面和参考剖面岩石地层学对比,认为三峡地区覃家庙群为跨传统下、中寒武统的地层单元。 |
| 关 键 词： | 三叶虫 生物地层 覃家庙群 下寒武统 中寒武统 兴山 湖北 |

| Abstract: | The Qinjiamiao Group in the Yangtze Gorge area is mainly composed of thin-bedded dolostones.Because this group yields scarce fossils,its depositional age was poorly constrained.New trilobites(e.g.,Kaotaia gedongensis Yuan & Zhao,Kunmingaspis yunnanensis Chang,Chittidilla sp.)collected from the basal Qinjiamiao Group at Gudongkou,Xingshan County of Hubei Province provide reliable evidence for a Cambrian age.Based on lithostratigraphical and biostratigraphical correlations among different sections in the Yang... |
