摘　　要：那拉提-红柳河缝合带是沿西天山构造带展布的哈萨克斯坦-准噶尔板块与塔里木板块间的缝合带,在西天山构造演化中具有举足轻重的地位.沿那拉提-红柳河缝合带分布的区域变质岩和动力变质岩(包括糜棱岩、固结型碎裂岩与未固结型碎裂岩)构成一个完整的演化序列,它们是不同演化阶段(时间),不同演化层次(空间)的产物.根据变质岩的时空演化特点可以看出,自泥盆纪早古南天山洋闭合碰撞之后,西天山构造带仍处在南北挤压应力场中保持强劲上升态势.The Nalati-Hongliuhe suture zone between the Kazakhstan-Junggar plate and Tarim plate along the Western Tianshan tectonic belt plays an important role in the tectonic evolution of Western Tianshan.The regional metamorphic rocks and dynamometamorphic rocks （including mylonite and cataclasite） distributed along the suture zone constitute an intact evolutionary sequence,which are the product of different evolutionary stages （time） and different evolutionary levels （space）.From the spatiotemporal evolution characteristics of the metamorphic rocks,it can be seen that,since the Early Ancient South Tianshan Ocean closed in Devonian period,the Western Tianshan tectonic belt has been strongly rising in the north-south compressive stress field.
