摘　　要：阿哈大洼Cu-W-Mo矿化区位于青海省柴北缘地区,该区具有丰富的岩浆演化活动,具有优越的成矿地质条件。本次研究通过对地质、钻孔信息进行综合研究评价,将钻孔光谱地球化学数据应用Voxler软件进行三维地球化学模型构建,识别出成矿元素地球化学三维空间分带特征,通过综合分析地质特征、深部成矿元素地球化学特征,综合评价成矿潜力认为阿哈大洼地区存在斑岩型钨钼矿+浅成低温热液脉型铅锌矿成矿系统。AhaDawa Cu-W-Mo mineralization area is located in the northern margin of Qaidam Basin in Qinghai Province.The area has rich magmatic evolution activities and superior metallogenic geological conditions.In this study,through the comprehensive research and evaluation of geological and drilling information,the three-dimensional geochemical model of drilling spectral geochemical data was constructed by Voxler software,and the three-dimensional spatial zoning characteristics of ore-forming element geochemistry were identified.Through the comprehensive analysis of geological characteristics and geochemical characteristics of deep ore-forming elements,the metallogenic potential was comprehensively evaluated.It is considered that there is a porphyry tungsten molybdenum deposit+epithermal vein type lead-zinc deposit metallogenic system in Aha Dawa area.
