Tian shan extends east - west in central asia , the tian shan range was formed in later paleozoic , and a few intramontan basins appeared in mesozoic . it uplifetd again in early miocene because of the north - south compression induced by the india - asia collision , so many active structures can be found in tian shan . active tectonics took actions during last ten thousands yeas , and surface traces of fault scarps , detached gullies and folds in alluvial deposit are apparent , so it is easy to distinguish them from other geological phenomema 天山位于亚洲中部，天山造山带形成于晚古生代，到中生代时，在天山内部形成了一些山间盆地，印度板块在始新世向北与欧亚板块碰撞，天山受南北向挤压力的作用再度于早中新世隆起，由于板块碰撞的持续进行，在天山山间及山前发育了许多的活动构造。
( 6 ) the geological significance of oblique - thrusting fault of sertengshan - xitieshan was discussed in this paper . the oblique - thrusting effect of sertengshan - xitieshan is the result of the long distance effction of himalayan orogenic belt intracontinent subducting , which is of great theory significance for studying regional structural framwork , relations between basins and mountains and oblique - thrusting effect of large - scale fault zone or orogen in northern qaidam basin . moreover , the result is of guidance significance for the forecast of combination gas , distributing and formation of nappe metal deposit in northern qaidam basin ( 6 )论文探讨了赛什腾? ?锡铁山斜向逆冲推覆构造的地质意义，认为赛什腾-锡铁山断裂斜冲作用是印度板块与欧亚板块碰撞、会聚的远程效应的结果，该认识对于研究柴北缘区域构造格局、盆山关系以及更大尺度的断裂带或造山带的斜向逆冲作用具有理论意义，对柴达木北缘的油气预测、推覆体金属矿床的分布、形成具有指导意义。
The three orogenic belts of sanjiang , qinling and xingan - mongolia developed in china from south to north , not only record the perfect history of the paleo - asia plates evolutionary process , and also reflect the effects of pacific plate subducting and indian - asia continent collision on continental margin and intern , especially these orogenic belts have experienced the main processes and metallogeny during the collision to post - collision and 我国从南往北发育的三江造山带、秦岭造山带和兴蒙造山带，记录了古板块演化旋回及其成矿作用的完整历史，也叠加了中新生代太平洋板块俯冲和印度板块碰撞导致的大陆边缘及陆内效应的信息。
Indus - tsangpo suture zone is the joint of indian plate and eurasia plate . the study on its evolution history can provide us dynamic evidence for continent - continent collision between indian plate and eurasia plate . then what is the formation mechanism and deformation history for the indus - tsangpo suture zone 雅鲁藏布江结合带是印度板块和欧亚板块碰撞的结合部位，研究其演化历史能够为解释印度-欧亚板块的陆-陆碰撞提供动力学方面依据，那么本区雅鲁藏布江结合带的形成机制和变形历史又是怎样的呢
The meso - cenozoic evolution of bachu fault - uplift is closely related to its south and north subsiding foredeep . under the background of indian plate subducting under asia - europe plate , bachu forebulge was greatly affected by the development of southwest depression and awati depression . almost all of its structure reversed , and as a result of it , both of its south and north boundary migrated . according to its evolution history and its feature , the authors tentatively use both - side migration model to interpret the evolution of compound forebulge . since triassic , almost all the spheres above lithosphere synchronously became flexure . because transpressional stress field became increasingly strong , bachu forebulge continued uplifting and big faults formed . then , bachu uplift , as a whole , slipped upward along those big faults and showed migrating toward thrust zone in plane . in tectonic tranquility , the lithosphere bounded back and in consequence of it , bachu uplift slipped down and showed migration toward craton , at that moment negative inversion structures developed . while the forebulge migrated toward its south and north foredeep , it was very possible that locally extensional stress appeared in the forebulge 在印度板块向欧亚板块俯冲的大背景下，巴楚前缘断隆受西南坳陷和阿瓦提凹陷的影响，新生代时构造体制发生反转，边界向南北迁移。根据其发育过程特征，作者用复合前缘隆起两端迁移模式对复合前缘隆起独特的构造发育史进行了解释：即三叠纪以来岩石圈各圈层同步挠曲变形。随着挤压应力场的增大，巴楚隆起在挠曲基础上不断抬升，形成几条大型断裂带。
