摘　　要：夏日哈木超大型铜镍矿床是青海东昆仑造山带首次发现的岩浆熔离型铜镍硫化物矿床。夏日哈木矿床的发现不仅实现了青海地质找矿矿种和类型上的重大突破,填补了青海无大型镍矿的历史,其发现和勘查过程也说明,对于重要成矿带化探数据的二次开发,特别是从以往大量弱小的、尚未检查的化探异常中筛选出具有找矿意义的异常,并进行及时验证,这对于获得找矿突破具有极其重要的启迪意义。夏日哈木矿床的发现也对地质找矿及研究工作产生了深远的影响,极大拓展了东昆仑地区及柴达木周缘的找矿新思维及找矿空间。这项工作充分表明,在任何重要的成矿区带,选用合适的地质及物化探工作是矿床发现的重要手段,对指导重要成矿带的成矿规律研究和找矿工作部署具有积极意义。The super large Xiarihamu Cu-Ni deposit is the first discovery of magmatic Cu-Ni sulfide ore depositin Qinghai east kunlun area, the discovery not only obtain benefit from geochemical field method, but also canimprove the technology and quality of work, and it is based on the sufficient research of geological, geophysical andgeochemical information, which can strengthen the comprehensive research and project work, and make the anomalies delineated, target area selection, prospecting results to be enhanced, and obtain effective verification results.Through the Xiarihamu Cu-Ni deposit discovery process, progress in exploration and the summary of the depositfeatures, to show the abnormal screening and comprehensive study of the thinking process of important metallogenicbelt for geochemical exploration data of secondary development, and through checking out the geochemical anomalieswith ore-prospecting significance exception to validate the breakthrough of prospecting space. Xiarihamu CwNideposit found can fully show that in any important mineralization zones, choosing suitable geological and geophysical-geochemical work is an important method for deposit discovering, which can provide guiding references for the metallo-genie regularity study of important metallogenie belt and the ore-prospecting work deployment.
