乌鲁木齐山前坳陷位于天山新生代再生造山带北侧，南以准噶尔南缘断裂与天山相隔，内部发育了几排逆断裂 背斜带，每一排构造带又由多个逆断裂 背斜组成。最南的齐古逆断裂 背斜带形成于中生代末，其北的玛纳斯逆断裂背斜带包含霍尔果斯、玛纳斯和吐谷鲁逆断裂背斜，形成于上新世末、早更新世初，受上、下２ 个滑脱面和断坡的控制，形成上、下２ 个背斜。再向北的独山子逆断裂背斜带由独山子、哈拉安德和安集海逆断裂背斜组成，形成于早、中更新世之间，主逆断裂向下在８ ～９ ｋｍ 深处的侏罗系中变为近水平滑脱面。此外，在独山子和吐谷鲁背斜的西北和东北还分别发育有正在形成之中的西湖和呼图壁隆起。研究了这些逆断裂 背斜带的地表和深部的构造特征、二维和三维几何学及运动学后指出，它们是在天山向准噶尔盆地扩展过程中发育于近水平滑脱面和不同断坡上的断展褶皱，独山子和安集海逆断裂 背斜的水平缩短量分别为２ ９００ ，１ ３５０ ｍ ，缩短速率分别为３９７ ，１８７ ｍ ｍ／ ａ。霍尔果斯、玛纳斯、吐谷鲁逆断裂 背斜的水平缩短量分别为５ ９００ ，６ ５００ ，６ ０００ ｍ ，相应的缩短速率分别为２０２，２２３ ，２０６ ｍ ｍ／ａ，准噶尔南缘断裂和乌鲁木齐山前坳陷第四纪?
The Urumqi piedmont depression is located on the north side of the Tianshan Cenozoic orogenic belt. The south margin of the southern margin of Junggar is separated from the Tianshan Mountain. Several rows of reverse thrust anticlines are developed in the interior of the Tianshan Mountains. Each row of structural zones is composed of several reverse fault anticlines . The southernmost Qigu anticline is formed at the end of the Mesozoic, and the northern Manas thrust rift zone contains the Horgos, Manas and Tugulu thrust rifts, formed at the end of the Pliocene Early Early Pleistocene, by the upper and lower two slip surface and the slope control, the formation of two anticlines. The northward Dushanzi reverse fracture anticline, consisting of Dushanzi, Halaand and Anjihai antic rift anticlinal, was formed between the Early and Middle Pleistocene, and the main thrust fault is 8 ~ 9 km deep Department of the Jurassic into a near-level smooth surface. In addition, the West Lake and the Hutubi Uplift are also being formed in the northwest and northeast of Dushanzi and Tugulu anticlines, respectively. The tectonic features of the surface and the deep of these reverse rift belts were studied. Two-dimensional and three-dimensional geometric and kinematic studies indicated that they developed on the near-horizontal plane and on different slopes during the extension of the Tianshan Mountains to the Junggar Basin The horizontal shortening of fault fold, Dushanzi and Anjihai anticline is 2 900 and 1 350 m respectively, and the shortening rates are 397 and 187 m m / a respectively. The horizontal shortening amounts of the Khorgos, Manas and Tugulu anticline faults are respectively 5 900, 6 500 and 6 000 m, and the corresponding shortening rates are respectively 202, 223 and 206 m m / a, southern margin of Junggar and Quaternary in Urumqi piedmont?
