摘　　要：中朝地台南部下、中寒武统 (风台组—张夏组 )可划分 9个三级层序。除底部的 DS-A层序外 ,其余 8个层序均可与中朝地台大部分地区进行对比。下部的 3个层序 (DS- A～ DS-2 )属 型层序 ,其余为 型层序。研究表明 ,本区的沉积层序除受早古生代全球海平面变化控制之外 。There are nine sequences within Lower Middle Cambrian(the Fengtai Zhangxia formations)in the southern Sino Korea Platform.Most of these sequences in this area,but the DS A,can be correlated with other sequences developing on the main part of the platform.Three sequences(DS A～DS 2)belong to type Ⅰ;the remainings belong to type Ⅲ.Apart from the factors of ‘global’sea level changes,the action of Qinling Palaeoplate towards the Sino Korea Platform is also very important to the developing of the sequences in the southern Sino Korea Platform during Early Palaeozoic.
