霍尔果斯背斜的构造分析与构造建模
|
摘要
通过运用断层相关褶皱理论的几何分析方法,对霍尔果斯的地震剖面及三维资料进行构造解析,认为霍尔果斯背斜由深、浅两组不同的构造组合叠加而成。深部构造是源于北天山的深部断层与反冲断层所构成的构造三角楔;中部为构造三角楔上盘褶皱诱导的褶皱调节断层;浅部地表所见的霍尔果斯断裂是深部基底滑脱面向上传递至安集海下部泥岩层内滑动,向上突破构造三角楔形成的褶皱南翼逆冲至地表的推覆构造。
By using the theory of fault-related fold geometry analysis method,the Huoerguosi of 3D seismic date and analysis of structural interpretation,finds the anticline is composed of two group structures: deep structure and shallow structure.The deep structure is triangle zone that constructed by a deep fault which rooted from the north of Tian mountain and a back fault;The shallow structure could be seen at surface is a over thrust which detachments along E2-3a and upwards cuts off the deep anticline's south lime,its hanging wall dip associated with the fault,is a monocline.
