    摘要
  • 松湖铁矿是近年来在西天山阿吾拉勒成矿带上新发现的中型铁矿床之一。从成矿地质背景、成矿条件方面入手，确定控矿因素。在此基础上，剖析物探、化探资料，建立松湖铁矿的找矿模型，同时，将松湖铁矿与中国及国外典型IOCG矿床进行对比，进行找矿前景分析。认为赋矿地层、断裂构造、岩浆岩等为重要的控矿因素；化探资料显示，异常套合较好，各异常中心显示良好的成矿特征和地球化学背景，并且各单元素异常的展布与区域断裂构造走向几乎完全一致，具有明显的断裂控矿特征，磁异常明显，对矿区外围4个磁异常进行钻探验证，其中3个异常已发现矿化或矿层；通过对比，发现松湖铁矿与IOCG型矿床有相似之处。综合上述特征，认为松湖矿床深部及外围具有较大的找矿前景，有望成为西天山阿吾拉勒成矿带上的大型铁矿床之一。
    Songhu iron ore deposit is one of the medium-sized iron ore deposits newly discovered iron ore depostis in Awulale metallogenic belt, of western Tianshan in rencent years. This article studied based on the geological background, and metallogenic conditiongs in a bid to determine its ore-controlling factors. On this basis, we analyzed geophysical, geochemical data information and established the an ore prospecting model. Meanwhile, we make a compare comparative study was carried out between typical IOCG ore deposit and Songhu iron deposit to facilitate prospecting analysis,. Research results indicate that Taking these factors,we make a prospecting. we consider Dahalajunshan ore-bearing formationstrata, faulting tectonics, and magmatic rock are are the important ore-controlling factors. By contrast, we find that Songhu iron ore has similarities with IOCG deposits. Geochemical data shows that the anomaly is well nested better, with the each anomaly centers showed showing good metallogenic characteristics and geochemical background; besides, the abnormal distribution of and each single element abnormal distribution and the regional faults tectonic trend strikeis almost exactly the same, showing a clear fracture-controlling featurefaults ore control. There is also an obvious magnetic anomaly is also obvious. There are four magnetic anomalies, after drilling verification experiment was conducted on four magnetic anomalies, laid outside the mining area, and three anomalies were found with three of which have been found abnormal mineralizationation or seamore formation. By comparisonthese characteristics, Songhu iron ore is similar to IOCG deposit in terms of many characteristics. Overall, we consider think that it hasthere is a large prospecting potential in the deep and surrounding area of Songhu iron ore. It is expected that Songhu iron ore will be become one of the largest iron oreore deposits in Awulale metallogenic belt.
