中朝地台南部下、中寒武统层序地层特征

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Ⅰ型层序，其余为Ⅲ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，秦岭板块的俯冲对中朝地台南部层序地层的发育也具有一 定的影响。%There are nine sequences within Lower-Middle Cambrian(the Fengtai-Zhangxia for mations)in the southern Sino-Korea Platform.Most of these sequences in this are a,but the DS-A,can be correlated with other sequences developing on the main pa rt of the platform.Three sequences(DS-A～DS-2)belong to type Ⅰ,the remaining s belong to type Ⅲ.Apart from the factors of ‘global’sea-level changes,the a ction of Qinling Palaeoplate towards the Sino-Korea Platform is also very impor tant to the developing of the sequences in the southern Sino-Korea Platform during Early Palaeozoic.
