摘　　要：阿尔泰南缘东部的构造变形以韧性变形为主,岩石变形过程与区域内金的矿化富集具有密切联系,区内已揭露的具工业价值的金矿床如萨尔布拉克金矿床、科克萨依金矿床、阿那拉提金矿床、南明水金矿床等均受区内构造变形制约,而与区域岩浆活动关系不大,这些金矿床的形成主要是构造变形(岩石变形)过程中深部热流体、大气水、变质水等多种流体混合所致。Tectonic-deformation of the rocks i n the east of southern margin of the Al tai Mountains gives priority to ductile deformation.The deformation process is close ly related to gold mineraliza-tion.Many gold deposits exposed in t he study area,having industrial value,e.g.,Sarebulake,Kekesayi,Analaty and Nanmingshui g old deposites,are all subject to tectonic deformation.Addi-tionally,they have not big connecti ons with regional magmatic activity.The formation of these gold deposits result from fluid-mixing i ncluding heat fluid,meteorologica l water and metamorphic water which was formed in the process of tec tonic deformation.
