| 摘 要： | 通过野外实测剖面、钻井、测井资料的研究,识别出8个层序界面,划分出7个三级层序.其中冶里组为SQ1,亮甲山组为SQ2,马家沟组两个(SQ3、SQ4),平凉组两个(SQ5、SQ6),背锅山组一个(SQ7).层序SQ1-SQ6只发育海侵体系域及高位体系域,层序SQ7发育低位体系域及海侵体系域,高位体系域被构造剥蚀.SQ1-...

| Abstract: | Sequence stratigraphy of Ordovician strata in the south part of Ordos area,which appears continuous,clear,and its corresponding drilling,the south,is the ideal locality to analyze the sequence stratigraphy.Based on the measured outcrop sections,drilling and logging data,the structure and lithology interfaces are identified,structure interfaces includes the boundary of the Ordovician tops and bottoms,the boundary of Majiagou Formation bottom and the Pingliang Formation bottom;the boundary of lithology and li... |
