| 摘 要： | 青龙村群在延边地体中具有重要地质意义。笔者通过对该群的工作和所获得的微古化石，认为青龙村群在层序上仅包含该区１：５万区调青龙村剖面中的中、下段，其上段不属于青龙村群范畴；青龙村群的形成地质时代应为晚震旦─早寒武世。

| Abstract: | The Qinglongcun Group in the Yanbian terrain has an important geological significance. Through the investigation for this Group and some micro-paleofossils,it has been consideredthat the Qinglong Groupi only involves mid-lower member of the Qinglongcun section. Ac-cording to regional investigation (scale 1 :50 000),the upper member does not belong to theQinglong Group in stratigraphic sequence. The geologic age of the Qinglong Group should bethe upper Sinian-Lower Cambrian. |
