豫北地区中元古界-寒武系岩层出露广泛,露头良好,层位稳定,沉积构造发育。是层序地层研究的理想区域。通过剖面基本层序研究、沉积相研究及区域追索进行了层序地层划分的探讨。共识别出二个I型(SB1)层序界面和12个Ⅱ型(SB2)层序界面,识别出2个超序(Ⅱ级层序,编号Ⅱ1-Ⅱ3)及15个层序(Ⅲ级层序,编号Ⅲ1-Ⅲ15)。

The Mesoprotozoic and Cambrian stratum were preserved well in Northern region of Henan Province, and the outcrops are in good condition to be researched. The sequence of these stratum is very steady and the sedimentary structures are typical for study. So, Northern region of Henan Province is a ideal research area for sequence stratigraphy. Through the research of section, sedimentary facies and regional survey, this paper made a discussion on the basic sequence stratigraphy. Two type I Sedimentary sequence interface (SB1) and twelve type ⅡSedimentary sequence interface (SB2) are found and two super sequence (Ⅱ level sequence and titled Ⅱ1- Ⅱ2) and fifteen sequence (Ⅲ level sequence and titled Ⅲ1- Ⅲ 15 ) are identified .
