新疆尼勒克县乔尔玛铁矿床地质特征及成因初探

摘要

The Qiaoerma ore deposits lies in the northeastern margin of the Yili Block, produced in Lower Carboniferous Dahalajunshan formation volcanic rocks. Mineralization rock is acidic tuff welded tuff, andesitic lithic tuff and andesitic volcanic breccia. Through regional geology, deposit geological characteristics, comparative study of the adjacent iron ore deposit geological characteristics and features within the same metallogenic belt,it is suggested that Qiaoerma iron ore genesis type belongs to volcanic hydrothermal iron deposit with a great prospect.%乔尔玛铁矿床位于伊犁地块东北缘，产于下石炭统大哈拉军山组火山岩中，成矿母岩为中酸性凝灰岩、熔结凝灰岩、安山质岩屑凝灰岩和安山质火山角砾岩。通过区域地质特征、矿区地质特征、矿体特征及同一成矿带内相邻铁矿床地质特征的对比研究，认为乔尔玛铁矿床成因类型为火山热液型铁矿床，找矿前景较好。
