塔里木盆地巴楚隆起海米罗斯断裂特征研究

Tectonic Characteristics of the Haimi-luosi Fault in the Bachu uplift of the Tarim basin

海米罗斯断裂带为塔里木盆地巴楚隆起和麦盖提斜坡的边界断裂。发育盖层滑脱和基底卷入式两种构造样式。深层为"Y"字型基底卷入式压扭型花状构造,浅层为盖层滑脱式断展构造。该断裂带呈三角形平面展布,东、西段构造特征差异较大。形成于加里东时期、海西晚期和喜山中晚期,定型于第四纪。

The Haimi-luosi Fault belt is the boundary fault belt between the Bachu uplift and the Maigaiti slope of The Tarim basin.There are 2fault structural styles that are cover detachmen-thrusting and basemen-involved faulting of the Haimi-luosi Fault.There are the＂Y＂-type basemen-involved shear-thrust Structure of the flower structures in deep section and the cover detachmen-thrusting fault-propagation structures in shallow section.The Haimi-luosi Fault belt is the triangular distribution.It exists the bigger dissimilarity of the Structural Characteristics in east and west areas of Haimi-luosi Fault belt.The Haimi-luosi Fault belt was generated in the Caledonian and the late Hercynian and the middle and late Himalayan period,and fixed in the Quaternary period.
