| 摘 要： | 以现代地层学理论为指导,分析多重地层划分单位的标准,首次引入层序地层学,对寒武系进行层序地层的划分。在寒武世地层中识别出一个“1”型不整合层序界面,五个“2”型不整合层序界面,将寒武系划为一个超层序,详细研究了超层序内部不同类型层序的沉积特征。重点讨论了地球化学分层、层序地层与传统地层学的关系,重新厘定了寒武纪的岩石地层单位的划分,以河南汝州阳坡剖面为例说明多重划分理论的具体应用。

| Abstract: | In light of the theory of modern stratigraphy,the authors analyze the standard of units from the multiple stratigaphic division.Sequence stratigraphy division is used for the Cambrian in Ruzhou area at the first time.One "1"uncormity suqence surface and five "2" uncormity suqence surfaces are distinguished out in it.The Cambrian can be thought a supersequence.And depositional characteristic of different classification sequence in it is researched carefully.The relationships between the geochemical stratigraphy,the sequence stratigraphy and the tradionarl stratigraphic units are also discussed.The lithostratigraphic division units are collated and stiuplated again for the Cambrian.Finally,taking the section of Ruzhou Yangpo as an example,the authors present the application of the multiple stratigraphic division. |
