东昆仑开木棋河地区镍矿成矿潜力分析

东昆仑夏日哈木铜镍硫化物矿床位于秦祁昆晚加里东造山系、东昆仑造山带西部祁漫塔格—都兰造山亚带,主要为铁、铜、镍、铅锌矿、钴矿、金矿。该带在区域上形成岩浆型铜镍硫化物矿床、矽卡岩型铁铜矿床和构造蚀变岩型金矿,夏日哈木铜镍硫化物矿床储量已达100万吨以上,显示了该区铜镍硫化物矿床找矿具有较大潜力,在夏日哈木矿床西部开木棋河地区从事地质找矿工作,通过对开木棋河地区成矿地质条件、地球物理、地球化学条件的综合分析认为该区寻找夏日哈木型铜镍硫化物矿床具有类似的地质条件,研究区具有良好的区域成矿背景,铜镍硫化物矿床在该成矿带已发现的矿床为超大型,该区和夏日哈木铜镍硫化物矿床处于同一成矿带,岩浆岩条件相似。辉石岩、辉长岩在该区分布较大,岩浆分异较好,地球物理和地球化学异常值高,浓集中心明显,具有寻找岩浆熔离型镍矿的有利条件,具有较大的找矿潜力。

Analysis of nickel metallogenic potential of Kaimuqihe area in east Kunlun

Copper and nickel sulfide deposits in Xiarihamu of east Kunlun is located in the Qinling-Qil- ian-Kulun late caledonian mountains, east Kunlun orogenic belt in west Qimantage-Dulan mountain belt, mainly contain iron, copper, nickel, zinc, cobalt, gold mine. Copper and Nickel sulfide deposits in Xiarihamu of east Kunlun reserves has reached more than 1 million tons, the discovery of the ore deposit shows the copper and nickel sulfide deposits prospecting in the area with large potential, The author in Xiarihamu of east kunlun ore deposit in the western Kaimuqihe area in the geological prospecting work, through Kaimuqihe regional metallogenie geological conditions, geophysical and geochemical conditions of comprehensive analysis that the area looking for Xiarihamu copper and nickel sulfide deposits with similar geological conditions. The study area has good regional metallogenic background, copper and nickel sulfide deposits in this metallogenic belt has been found is very large, the area and Xiarihamu copper and nickel sulfide deposits in the same metallogenic belt, similar to magmatic rock conditions. Pyroxenite, gabbro distribution in the region is bigger, better magmatic differentiation, geophysical and geochemical anomaly value is high, the thick concentrated heart clear. Therefore, the study area is looking for the advantage of magma and magmatic liquation type nickel, prospecting has great prospecting potential in the study area.
