准噶尔盆地南缘古牧地构造建模分析
|
摘要
准噶尔盆地南缘受喜马拉雅运动晚期天山活动的影响,形成一系列的背斜及相关断裂。由于地表及地下地质条件复杂,地震反射资料品质差,构造样式在判识时具有多解性。为了建立南缘的构造样式,以古牧地构造分析为例,以断层相关褶皱理论为理论指导,利用构造建模技术作为解剖复杂构造的手段熏建立适合该地区实际情况的构造地质模型,同时阐述复杂构造建模的过程。
The southern margin of Junggar basin underwent Tianshan movement in late Himalayan orogeny and formed a series of anticlines and related faults.Owing to its complex surface and subsurface geologic conditions,the seismic reflection data from this area are poor and the structural style varies and is always troublesome in discrimination.In order to establish the proper structural style,this paper takes the structural description of Gumudi anticline as an example,the fault-folded theory as a guide,and the structural modeling technique as a tool for anatomizing complex structures,finally,develops a model of structural geology fitting for real situation of this area.The procedure for modeling is also presented herein.
