| 摘 要： | 塔北轮南古隆起于加里东中—晚期形成凸起,海西早期受区域性挤压抬升形成向西南倾伏的北东向展布的大型鼻凸,在长期的抬升暴露风化剥蚀过程中形成轮南古潜山.根据区域地质背景和地层沉积特征(岩性、沉积构造等)研究,结合现场已有的构造解释、地震、油气显示、测试等各种资料,利用单因素分析法,划分了三角洲-泻湖-潮坪沉积相,其中以泻湖-潮坪沉积相占优势,建立了其沉积模式,对沉积相纵横向展布进行了对比,分析了沉积相平面上的分布规律.

| Abstract: | The salient of Lunnan palaeohigh in the northern Tarim Basin formed in the middle-late period of Caledonian,and a large southwest-plunging nose-shaped salient in NE trending was formed because of regional extrusion lifting in the early stage of Hercynian.The nose-shaped salient is graduately evolved into Lunnan burial hill in the process of long-term weathering denudation.Based on the study of regional geologic background and depositional characteristic(lithology,sedimentary structure,etc.),and structural i... |
