| 摘 要： | 根据野外露头、钻井岩性剖面和地球物理资料等,在鄂尔多斯盆地中生界可识别出的层序界面有古暴露剥蚀面、不整合界面、河流回春作用面、冲刷侵蚀面、岩性与岩相转换面、上超面、最大湖泛面。在详细讨论各类型界面特征的基础上,将成因划分为:构造运动造山侵蚀不整合界面、升隆侵蚀不整合界面、暴露不整合界面、冲刷侵蚀不整合界面、最大湖泛沉积界面5种类型。

| Abstract: | Through analyzing flied geologic sections, drilling and geophysical data, this paper identified seventypes of sequence boundary surfaces in Mesozoic Ordos basin. They are paleo-exposing surface, unconformitysurface, erosion surface of river rejuvenation, washing erosion surface, transition surface of rock character, on-lap surface, flooding furface. The features of the surfaces and the origin types of sequence boundary surface werestudied. According to the features, those surfaces were divided into five kinds of types. |
