摘　　要：甘肃北山地区是我国西北地区一个重要的多金属成矿带。近年来在北山黑山—大山头一带发现多处铜镍矿化基性-超基性岩杂岩体,大山头岩体即是其中之一,最新勘查显示大山头岩体具有较好的铜镍成矿潜力。在综合分析大山头岩体特征、成矿地质条件、地球化学和地球物理异常特征的基础上,建立了地质-地球物理-地球化学综合找矿模型,对于该地区类似矿床的发现和评价具有一定的参考作用。Gansu beishan area is an important polymetallic metallogenic belt in northwest of China.In recent years,a few of mineralization basic-ultrabasic complex rock body are found in Heishan-Datoushan area of Beishan,the Dashantou basic-ultrabasic complex rock body is one of them. The latest exploration results show that,the Dashantou basic-ultrabasic complex rock body has good Cu-Ni metallogenic potential. The characteristics of the Dashantou rock mass,mineralization geological condition and characteristics of geochemistry anomaly and geophysical anomaly are analyzed comprehensively. Based on this,the geology-geophysical-geochemistry prospecting model is established. The research results have important significance to discovery and evaluation of the similar ore deposits.
