摘　　要：试图以板块构造观点和包括以海平面变化沉积层序分析方法在内的现代沉积学理论,对华北地台南缘(河南部分)震旦纪—早古生代盆地建造作概略的分析,此外,对相关问题进行了讨论.认为:1华北地台寒武—奥陶纪二级海平面变化由两个二级旋迴组成:早寒武世沧浪铺中期—早奥陶世冶里期构成旋迴A,早奥陶世亮甲山晚期—中奥陶世峰峰期构成旋迴B.2中寒武世末期至早奥陶世冶里期由南向北的缓慢抬升,导致了华北地台古地势由南低北高转变为南高北低.In this paper, using the concept of plate tectonics and the modern sedimentology theory including sea level changes of sedimentary sequence analysis method, we gave a summary analysis of the southern margin of North China platform （Henan）Sinian-Early Paleozoic basin formation. In addition we discussed related issues, and deduced the conclusion as follows. （1）Two secondary sea level change of North China platform Cambrian-Ordovieian is consist of two secondary cycles that named Cycle A and B： Cycle A is from the medium term of Early Cambrian Canglangpu to Yeli formation of Early Ordovician; and Cycle B is from the later formation of Early Ordovician liangjiashan formation to fengfeng formation of middle Ordovician. （2）The slow uplift from south to north happened in the time from the last phase of middle Cambrian to early Ordovician Yeli formation, leads to the ancient topography＇ s which primary declining from north to south decline from south to north.
