摘　　要：研究认为巴楚断隆地区在加里东早期和海西晚期曾遭受过两次强烈的拉张作用,从而引发了大规模火山喷发,表现为裂谷型拉张环境。从加里东晚期到海西晚期以及从中、新生代到现今以来,该区发生明显反转,大面积缺失中生代沉积。新生代构造表现为以挤压和走滑作用为主,形成了许多复杂多样的逆冲断层和正花状构造。位于巴楚断隆西侧的色力布亚断裂在经历了两次拉张作用和反转后,形成了具有深层逆冲断裂和浅层逆冲推覆断裂的构造特征。From the construction of history in Bachu uplift,it shall be seen the region has suffered two intense extension effects at Early Caledonian and Late Hercynian. Large-scale volcanic eruption and rift extensional environment are leaded by the two extensions. From Late Caledonian to Late Hercynian,and since the Mesozoic-Cenozoic to the present,the area develops apparent inversion,and lack of large area deposition of Mesozoic.Cenozoic structures are complexity thrust fault and positive flower structure by extrusion and strike-slip effects.Experienced two post-tension effects and reverse,the selibuya fault in the west side of Bachu uplift has formed the structure characteristics with deep thrust and shallow thrust.
