| 摘 要： | 新疆觉罗塔格韧性变形带,惯称秋格明塔什-黄山韧性剪切带,发育于吐哈地块和中天山地块之间的EW向石炭系火山-沉积建造中,由一组走向EW、产状陡立的透入性片理组成。韧性变形带内韧性构造形迹发育,并可分为4个等级:大型构造、小型构造、微观构造和超微观构造。不同级别构造形迹的组构分析表明,觉罗塔格韧性变形带的内部组构是对称的,这意味着其成因于对称的构造变形。与主界面平行的大量压性构造形迹的产出,说明该对称组构成因于与垂直变形带(面)的共轴挤压作用,即觉罗塔格韧性变形带是一个韧性挤压带。

| Abstract: | The ductile deformation zone in Jiaoluotage area in Xinjiang Autonomous Region developed in E-W-trending Carboniferous volcanic and sedimentary formation between the Tuha Block and the Mid-Tianshan Block,and comprises a set of E-W-striking and upright penetrative foliation.The deformation features can be broadly divided into four orders in size.Fabric analysis of them indicates a symmetry of the deformation,implying an origin of symmetrical tectonic deformation.Development of many compressive structural features parallel to the major boundary shows that they may result from compression perpendicular to the deformation zone (plane).The ductile deformation zone in Jiaoluotage area is,therefore,a ductile compressed zone. |

| Keywords: | Xinjiang Jiaoluotage ductile deformation zone fabric |
