| 摘 要： | 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。

| Abstract: | The west of Henan Province is one of the regions where the Mesoproterozoic and Neoproterozoic erathems are well developed and is also an ideal place for the study of sequence stratigraphy. The article deals mainly with the sedimentology and sequence stratigraphy of Meso Neoproterozoic in the area. By the analysis of the sedimentary features, the main types and characteristics of parasequences, integrating with the study of sequence boundary and maximum flooding surface, the sedimentary system tracts and sequences are determined. 6 sedimentary systems, 13 sedimentary facies and 38 microfacies are recognized in the region. Ruyang Group is divided into 6 third order sequences, Luoyu Group into 2 third order sequences and Sinonian is divided into 3 third order sequences. |
