塔什库尔干铁矿带位于印度板块与塔里木板块结合部位的西昆仑造山带，是新疆地区新近发现的大型铁矿带，发育独特的黄铁矿-硬石膏-磁铁矿建造。区内研究基础比较薄弱，还存在一些关键问题和争议有待解决。本论文主要针对区内大型的赞坎和叶里克矿床展开磁铁矿原位微量元素分析、黄铁矿S同位素和Re-Os同位素（第一次）分析以及围岩、含矿火山岩锆石U-Pb同位素分析，以期约束矿床成因类型，揭示膏-铁建造成因，为区内找矿工作提供一定指导。本文取得的主要成果和认识有：1. 赞坎和叶里克铁矿床均位于塔什库尔干铁矿带，属区内典型的大型矿床。赋矿地层均为布伦阔勒群，具有相似的矿床地质特征、矿石矿物组合，均发育区内独特的黄铁矿-石膏-磁铁矿建造，为同一成矿事件的产物；2. 磁铁矿高Al、Ti、V含量，高Ni/Cr比值以及低Ti/V比值等微量元素特征表明，磁铁矿形成于海底偏还原性的高温热液体系，约束矿床类型为海相火山岩型铁矿；3. 围岩锆石U-Pb年龄及含矿火山岩U-Pb年龄共同限定成矿时间为早寒武世，矿床形成与原特提斯洋南向俯冲到西南昆仑地体之下引发的火山弧岩浆作用有关；4. 黄铁矿S同位素组成δ34 S异常高的特点（平均29.0‰），反映成矿沉积水体环境相对封闭，具有较低硫酸盐浓度，高的海水硫酸盐δ34S背景值，并且初步认为其是对全球性“雪球”事件的一个响应；5. 特殊的成矿构造环境和沉淀背景共同作用造成了这种特殊的黄铁矿-硬石膏-磁铁矿建造；6. 研究对于区内找矿勘探具有一定的指导意义，成矿区域位于Fe、V、Mn、Ti、Co 组合的异常浓度中心外带，伴随有W、Th、Be、F、La、U、Sr 等多元素的后期高温元素，并且没有明显的Cr、Ni 异常，指示岩浆活动的存在，可能存在更大规模的富铁矿体。本文仍然存在一些不足和关键问题有待解决，需要根据已有的认识和发现的问题，展开进一步的调查研究工作，以期更好地刻画成矿过程，为我国大型富铁矿的勘探工作提供指导。

The Taxkorgan iron ore belt is located in the west Kunlun orogenic belt where the Indian plate meets theTtarim plate and is an important high-grade iron belt recent discovered in Xinjiang Province west China. Unique pyrite-anhydrite-magnetite formations are developed in the area. This area has been rarely studied, and there are still some key problems and controversies to be solved. Therefore, in this paper, the in-situ trace element analysis of magnetite, S isotope and Re-Os isotope analysis of pyrite(for the first time), and U-Pb isotope analysis of zircon from wall rock and mineralized volcanic rock are carried out for the large-scale Zankan and Erik deposits in the area, so as to constrain the genetic types of the deposits, reveal the genesis of pyrite-anhydrite-magnetite formations, and provide certain guidance for the ore-prospecting work in the area. The main achievements and conclusions of this paper are as follows:1. The Zankan and Erik iron deposits are both typical large-scale deposits in the region and located in the Taxkorgan iron ore belt. The ore-bearing strata are all Bulunkuole meta-volcano-sedimentary sucession, with similar geological characteristics of ore deposits, mineral assemblages of ores and minerals, and unique pyrite-anhydrite-magnetite formations in the developed area.2. The high content of Al, Ti and V, high Ni/Cr, low Ti/V and other trace elements of magnetite indicate that magnetite was formed in the high-temperature hydrothermal system with relatively reduction at sea bottom, and the restrict deposit type as marine volcanic-sedimentary hosted Fe oxide deposit formed at or near the seafloor in submarine volcanic settings. 3. The U-Pb age of the wall rock and mineralized volcanic rock zircon define the metallogenic time as early Cambrian. The formation of the deposit is related to the volcanic arc magmatism caused by southward subduction of Proto-Tethyan plate.4. The anomalous high S isotope composition (δ34 S ) of pyrite (average 29.0‰) reflect that the mineralization and sedimentary environment of sea water at that time was a relatively closed water environment with low sulfate concentration and high background value of ocean δ34 S, and it was preliminarily considered as a response to the global "snowball" event;5. The formation of gypsolyte-iron formation is closely related to special time and space, and the combination of special metallogenic tectonic environment and sedimentary background results in the special pyrite - anhydrite -magnetite formation;6. The study has certain guiding significance for ore prospecting and exploration in the area. The mineralization area located in the belt outside the abnormal concentration center of Fe, V, Mn, Ti and Co combination, accompanied by W, Th, Be, F, La, U, Sr and other high-temperature elements in the later stage, with no obvious Cr and Ni anomalies, indicating magmatic activity, there may be rich iron ore bodies.There are still some deficiencies and key problems to be solved in this paper, and further investigation and research work should be carried out according to the existing conclusions and problems, so as to better depict the mineralization process and provide guidance for the exploration of large-scale rich iron ore in China.
