摘　　要：新疆塔什库尔干县沉积变质型铁矿位于西昆仑南部慕士塔挌-阿克赛钦Fe-Cu-Au-PbZn成矿带,该区域地质运动强烈,铁矿资源富集。目前带内已发现30多个矿床、点,局部具有发现超大型铁矿的潜力。通过对区域地质特征的归纳分析,基于矿床展布特征研究、成矿及时间演化规律的分析,建立了塔什库尔干地区沉积变质型铁矿成矿模型,确立了该区域成矿时代与全球前寒武系BIF型相近。进一步划分了该区沉积变质型铁矿的4个关键含矿层位,为提高找矿工作的靶向性奠定了理论依据。The sedimentary metamorphic iron deposit in Tashkurgan County,Xinjiang is located in the Mushitage-Aksaiqin Fe-Cu-Au-Pb-Zn metallogenic belt in the south of western Kunlun.The geologi⁃cal movement in this area is strong and the iron ore resources are enriched.At present,more than 30 depos⁃its and points have been found in the belt,and there is potential for the discovery of super-large iron depos⁃its in some areas.Through the induction and analysis of regional geological characteristics,based on the study of deposit distribution characteristics,mineralization and time evolution law,the metallogenic model of sedimentary metamorphic iron ore in Tashkurgan area is established,and the metallogenic age of this area is similar to that of Precambrian BIF type in the world.Four key ore-bearing horizons of sedimentary meta⁃morphic iron deposits in this area are further divided,which lays a theoretical basis for improving the target⁃ing of prospecting work.
