摘要
1996年以来我国早前寒武纪地层研究的新进展主要包括以下五个方面的内容 :1)古太古代陈台沟表壳岩的发现 ;2 )五台群时代研究的新进展 ;3)阜平群、涑水杂岩和达肯大坂岩群的解体和重组 ;4 )根据新的年龄数据 ,叠布斯格岩群、双山子岩群、界河口岩群、吕梁岩群、熊耳群、龙首山岩群和宿松群的时代进一步得到了肯定或做了重要的修正 ;5 )美岱召岩群、官都岩群、寻乌岩群、连云山岩群和苍溪群等古元古代地层单位的建立。
This paper chiefly introduces the new progress since 1996 in study on early Precambrian stratigraphy of China. It contains five aspects:1) the discovery of the Paleoarchean Chentaigou Supracrusts; 2) new progress in study on isotopic ages of the Wutai Group; 3) disintegration and reconstruction of the Fuping Group, Sushui Complex and Dakendaban Group Complex; 4) based on the new isotopic dating, the ages of the Diebusige Group Complex, Shuangshanzi Group Complex, Jiehekou Group Complex, Luliang Group Complex, Xiong'er Group Complex, Longshoushan Group Complex and Susong Group Complex have been further confirmed or revised; 5) new stratigraphic units of the Meidaizhao Group Complex, Guandou Group Complex, Xunwu Group Complex, Lianyunshan Group Complex and Cangxi Group have been established.
