摘要
东天山脆-韧性变形转换带是该地区一条重要的构造变形带，该带近EW向波状延伸，长600 km，宽10(20 km，分为南北两个子带。独特的构造背景，使其成为东天山金成矿带的主体部分。脆-韧性转换变形是与区域性韧性剪切带密切相关的一类构造现象，其过程是一个动力学过程，变形转换过程中的一系列动力学行为，是带内成矿流体活动的主导因素，成矿流体的活动又促进了岩石矿物变质、变形作用，因此脆-韧性变形转换带具有极其重要的成矿意义。
The brittle-ductile deformation transition zone in Eastern Tianshan is an important tectonic deformation zone. It extends wavy from east to west with 600km long and 10 to 20km wide. The main is divided into two sub-zones. Its special tectonic setting made it the main part of Eastern Tianshan gold deposits belt. The deformation of brittle-ductile transition is a type of tectonic phenomena related closely to the regional ductile shear zone. Its transition process is a dynamics process. A series of dynamics behaviors in the processes are the leading factor of dynamic thermal fluid moving, on the other hand, the dynamic thermal fluid moving can promote the rocks and minerals' metamorphism and deformation. So it is though of having great significance to ore -forming.
