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。

关 键 词:青龙村群 地质时代 地层 晚震旦世

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.
Keywords:Qinglongcun Group Stratohorizon Geological age Micro-paleofossils
