OUTCROP SEQUENCE STRATIGRAPHY OF THENEOPROTEROZIC IN THE HUNJIANG AREA,JILIN PROVINCE

摘要: 吉林新元古界被识别出三个层序，重点研究了上震旦统万隆组、八道江组及青沟子组的副层序类型及堆叠形式；用层序地层理论讨论了组的穿时，重新研究了已有年龄资料；并根据层序地层、事件地层、生物地层与年代地层资料，对吉林与辽南新元古界提出了新的对比方案。

Abstract: Three sequences have been distinguished in the Neoproterozoic strata in the southern partof Jilin. The authors mainly discuss the types of parasequences and their stacking patterns ofthe Wanlong,Badaojiang and Qinggouzi Formations and diachronism of the formations usingthe theory of sequence stratigraphy and again analyse the available age data. Besides accordingto sequence stratigraphy, event stratigraphy, biostratigraphy and chronostratigraphy,the au-thors advance a new scheme of stratigraphic correlation of the Neoproterozoic of Jilin andsouthern Liaoning.
