塔里木盆地车尔臣断裂带构造—岩相特征及形成机理探讨
|
摘要
车尔臣断裂带的构造特征、寒武系—下奥陶统地层地震相特征与沉积相展布、构造与岩相之间关系的研究表明,车尔臣断裂构造带具有“三段式”结构。西段与东段相似,为巨厚的碳酸盐岩建造,刚性强,以断裂形式释放应力,所形成的构造带成排发育,圈闭面积小而个数多;中段塔东低凸起以泥岩建造为主,岩层刚性弱,以塑性变形为主,构造带不发育,构造样式主要为古生界的宽缓背斜,圈闭面积大而个数少。通过沉积相和构造综合研究证实存在2个岩性圈闭带:古城奥陶系礁滩相岩性圈闭带和罗布泊奥陶系礁滩相构造—岩性复合圈闭带。
Based on the study of Cherchen fault zone's structure characteristics,Cambrian-Ordovician seismic facies characteristic and sedimentary facies distribution,the relationship between structure and rock facies,the authors concluded that the Cherchen fault zone has three sectors. West and east sectors are similar to each other made up of super thick carbonate in which the rigidity was so strong that many faults generated and produced a series of structure zones. Their trap's area is smaller and much in number. Middle sectors-Tadong low salient was made up of mudstone,in which the rigidity was weak and produced plastic deformation,structure zones were not developed,and the styles of structure are Paleozoic even anticlines. Their trap's area is wider and less in number. Through the research of sedimentary facies and structure,the authors proved two lithostratigraphic trap zones:Gucheng Ordovician reef beach facies lithostratigraphic trap zone and Luobupo Ordovician reef beach facies structure-lithostratigraphic trap zone.
