新疆富铁矿成矿特征及主攻类型成矿模式探讨

DISCUSSION OF METALLOGENIC MODELS,MINERALIZATION CHARACTERISTIC AND MAIN TYPE OF RICH IRON ORE OF XINJIANG

富铁矿资源是我国紧缺战略资源,远远不能满足我国钢铁生产需求.近年来新疆富铁矿找矿重大突破表明,富铁矿是新疆优势资源,是我国寻找富铁矿重点远景区.从新疆实际地质条件和成矿特征出发,初步形成植根于新疆实际的"新疆富铁矿成矿新理论及主攻类型的成矿模式",并分别构建了"上叠裂谷火山岩型富铁矿成矿模式"、"沉积变质-热液加富型铁矿床成矿模式"和"海相沉积-加富型菱铁矿矿床成矿模式".这些成矿新认识和新成矿模式在本区铁矿评价中广泛应用,取得很好效果,丰富了铁矿成矿理论,拓展了新疆铁矿找矿领域.

Rich iron ore resources are scarce strategic resource in China, it doesn＇t meet the demand of steel production of our country, in recent years, the major breakthrough of xinjiang rich iron ore shows, that the rich iron ore is the advantage resources in xinjiang,and xinjiang is china＇s most important prospective area to find rich iron ore,start from xinjiang＇s actual geological conditions and mineralization characteristics, and initially formed a theory rooted in the reality in xinjiang,＂the ore- forming model,new mineralization theory, and main type of xinjiang rich iron ore＇,and respectively build the ＂ore-forming model of the wide rift volcanic rich iron ore＂,＂ore-forming model of sedimentary-metamorphic -hydrothermal enrichment-type iron ore deposits＂,＂ore-forming model of marine deposits-plus rich siderite rich type deposits＂,this new understanding and new ore-forming models is widely used in this area of the evaluation of iron ore.And get good results,enriching the theory of iron ore,expansion the prospecting area in xinjiang.
