摘　　要：卡拉麦里地区是新疆重要的金成矿带,该区经历了多次的拉伸—碰撞过程,在晚古生代以后卡拉麦里形成有限洋盆,伴随着大规模的洋壳闭合及碰撞造山运动,区域内岩石发生的变质变形、蛇绿岩就位、大规模的中酸性(碱性)花岗岩的侵入,为该区金矿的形成提供了良好的成矿地质条件。从区域构造运动、热液活动及金矿的空间分布等角度对该地区的金矿成矿地质条件及找矿前景进行了论述,通过对地质背景、地球化学特征分析,划分出4种矿床类型和6个找矿远景区。Kalamaili region is an important metallogenic belt of gold deposit in Xinjiang.During multiple stretch and collision processes,the limited ocean basin is formed in this area accompanying for the massive oceanic lithosphere and crash orogenesis.Good geological metallogenetic conditions of the gold ore formation is provided according to metamorphic and transformation of rock,the properly seated of the ophiolites and the invaded of the massive intermediate acidic（alkalinitic）granite.Gold metallogenic condition analysis and prospecting prediction in Kalamaili region of Xinjiang is discussed through the region tectonic movement,hydrothermal activity and the spatial distribution of gold deposit.Four types of deposits and six prospecting potential areas are marked out through the geological background and geochemical characteristics analysis.
