摘要
库鲁克塔格是新疆前寒武纪出露较全的地区,然而该区区域成矿规律研究程度非常低.通过对研究区已有资料进行总结分析,系统阐述研究区矿床类型,并对其成矿系列进行划分.研究区从太古代到早古生代形成了7个主要的岩浆构造演化阶段:古太古代陆核形成阶段(3.3~3.0Ga)、新太古代-古元古代陆壳增生改造阶段(2.6~2.3Ga)、古元古代中晚期陆壳改造阶段(2.1~1.8Ga)、中元古代晚期-新元古代早期造山运动阶段(1.1~0.86Ga)、新元古代中期后碰撞伸展阶段(830~800Ma)、新元古代中晚期陆内裂解阶段(770~600Ma)和早古生代造陆运动阶段.成矿作用主要发生在古元古代、新元古代及早古生代.依据各构造演化阶段、含矿建造特征及矿床成因特征,将库鲁克塔格成矿作用类型总结为以下6个主要成矿系列,即形成于古元古代陆壳增生改造环境下的Fe-P-Cu-Au系列、新元古代俯冲碰撞环境下的Cu-Au系列、新元古代后碰撞环境下的Cu-Mo-Au-Fe-P-REE系列、新元古代裂解环境下的Cu-Ni系列、早古生代沉积盆地中Ag-V-Mo-Au-U-P系列和早古生代俯冲岛弧环境下的Cu-Au系列.
