    Prospecting thinking and model for the Ketinghaer porphyry copper molybdenum deposit in the East Kunlun Mountains

    • 摘要: 提要: 东昆仑之祁漫塔格成矿带以矿床类型、金属种类丰富多样为特征, 以矽卡岩型矿床为典型, 是地质学者研究的热点地区之一。近年来此成矿带中的斑岩型铜钼矿找矿不断有新的突破, 2013年在该成矿带东侧克停哈尔地区又新发现一典型斑岩型铜钼矿。矿区地层以古元古代金水口岩群为主, 岩性为片麻岩、大理岩等变质岩, 华力西期、印支期中酸性岩体广泛侵入, 后者为赋矿岩石, 岩体内有隐伏的小斑岩体及隐爆角砾岩, 矿区北西向、北东向构造发育, 有多个物化探异常分布。本区找矿突破是在全面认识分析以上成矿地质条件、物化探异常特征, 类比已知典型铜钼矿床基础上, 初步建立寻找斑岩型矿床的找矿思路, 并据此思路开展勘查工作, 最终取得了找矿突破, 进而总结出克停哈尔斑岩型铜钼矿的找矿思路方法, 建立了地质-地球化学-地球物理综合信息找矿模型, 为区域上开展同类型矿床的找矿工作提供了思路和方向。

       

      Abstract: Abstract: The Qimantag metallogenic belt in the East Kunlun Mountains is characterized by a large variety of deposit types and metallic kinds, with skarn deposits being the typical type. Hence, this belt has become one of the hotspots among geologists. In recent years, the prospecting for porphyry copper molybdenum deposit has achieved new breakthroughs continually in this metallogenic belt. In Ketinghaer, to the east of this belt, a new porphyry copper molybdenum deposit was discovered in 2013. The strata in this area belong mainly to Paleoproterozoic Jinshuikou Group, and the main rocks are metamorphic rocks, such as gneiss and marble. The Variscan and Indosinian intermediate-acidic intrusive rocks are widely distributed in this area, with the Indosinian intrusive rocks being the host rocks; within the rock bodies, there are small porphyry mass and cryptoexplosion breccia. In addition, the NW-, NE-trending structures and multiple geophysical-geochemical anomalies are also distributed in this area. Through a comprehensive analysis of the above conditions including geological conditions, geophysical-geochemical anomalies, and characteristics of typical porphyry copper molybdenum deposits, the authors tentatively summed up the prospecting thinking for porphyry deposits. On such a basis, the prospecting work was carried out, which led to the breakthrough finally. And then, the authors summarized the prospecting thinking and methods for the Ketinghaer porphyry copper molybdenum deposit, and established a geological-geochemical-geophysical comprehensive model so as to provide the train of thought and orientation in search for the same type of deposits in this region.
