摘　　要：内蒙古苏尼特左旗地区韧性剪切带分布有北、中、南三带,南北近等距分布,三条韧性剪切带的形成时间均为二叠纪末一三叠纪,皆为左行走滑韧性剪切带,三条剪切带中以巴彦温多尔—巴润萨拉韧性剪切带最为典型。韧性剪切带及其相关次级构造是该区重要的导矿及容矿构造,韧性剪切带的长期及多期活动为成矿流体的活化及运移提供了动力及热源,第二期和第三期构造变形期是主要成矿期,形成巴彦温多尔中型金矿床。Three ductile shear zones with left-lateral shear distributed separately on the north, middle and south part in Sunite Zuoqi area, Inner Mongolia, and formed in the late Permian to Triassic period. These 3 ductile shear zones were characteristic of equal interval distance. Of the 3 ductile shear zones, the Bayanwenduoer shear zone possesses the most typical characteristics of the ductile shear deformation. The ductile shear zones and their associated proximate structures were the main ore-transmitting and ore-host structures in this area. The repeatedly and long time activity of ductile shear zones provided the driving force and ore materials for activation and mo- tion of mining liquid. The second and third structure deformation periods are the main ore-forming period and the Bayanwenduoer Gold Deposit was formed in this period.
