从沉积特征研究入手，确定各种沉积相、微相及沉积体系，将区内中、新元古界划分为６种沉积体系、１３种沉积相和３８种微相，对副层序的主要类型及其特征进行了分析，结合层序界面和最大海泛面的研究确定了沉积体系域和层序。在中元古代汝阳群中划分出６个层序，新元古代洛峪群划分出２个层序，震旦系划分出３个层序。在此基础上对华北地台南部中、新元古代相对海平面变化特征进行了探讨。
Beginning with the study of sedimentary characteristics, various sedimentary facies, microfacies and sedimentary systems were determined, and the middle and new Proterozoic zones were divided into six sedimentary systems, 13 sedimentary facies and 38 microfacies, Type and its characteristics were analyzed. The sedimentary system domain and sequence were confirmed by the study of sequence boundary and maximum sea surface. In the Middle Proterozoic Ruyang Group, 6 sequences are divided into two series. Neoproterozoic Luoyu Group is divided into two sequences, Sinian Department is divided into three sequences. On this basis, the characteristics of relative sea level changes in the middle and Neoproterozoic of the southern part of North China Platform are discussed.
