摘　　要：钴是全球战略性关键矿产,对国民经济、国家安全和新兴产业发展具有关键作用。钴资源的国内供应基本来源于岩浆铜镍硫化物矿床冶炼铜镍的副产品,尚未发现独立钴矿床。准噶尔北缘成矿带蕴都卡拉钴矿,是除岩浆硫化物矿床类型之外的新发现。笔者通过蕴都卡拉钴矿成矿特征研究,初步认为钴矿聚集于闪长岩与玄武岩接触带的构造破碎带内,沿北西向断裂两侧分布,表现了钴、铜、金的典型组合,属于岩浆热液型矿床。在蕴都卡拉外围沿北西向断裂两侧发育多处闪长岩与玄武岩的接触部位,钴矿成矿条件优越,表现出较大的钴矿找矿潜力。笔者通过蕴都卡拉钴矿富集规律和成矿特征研究,旨在揭示钴矿产资源成矿潜力和找矿新靶区,支撑服务战略性矿产找矿行动,缓解中国钴矿产资源安全供应压力,降低安全风险。Cobalt is global strategic critical minerals,which is of great strategic significance to the national economy,national security,and technological development.Therefore,it is urgent to strengthen the study of cobalt mineralization regularity,to develop efficient exploration technology,and to search the new continuous resources.The cobalt resources stemed mainly from by-product smelt Cu and Ni from magmatic sulfide deposits in China,independent cobalt deposit not found.The Yundukala cobalt deposit from northern margin of Junggar metallogenic belt is newly discovered in China.The paper preliminary think that cobalt accumulation on the contact zone between diorite and basalt,at the same time,structural broken belt,the distribution of cobalt minerlization is made along both sides of the NW-SE fracture,it shows a typical combination of cabalt,copper and gold,and belongs to magmatic hydrothermal type deposit.Moreover,there developing many contact parts diorite and basalt along both sides of NW-SE fracture in Yundukala peripheral area,they have advantageous metallogenic conditions of cobalt deposits,and showing great prospecting potential.The paper intends to re-search metallogenic regularity and mineralization characteristics by Yundukala cobalt.This work could reveal the metallogenic potential of cobalt mineral resources,determine new prospecting targets,support the strategic mineral prospecting operations,and enhance the ability to ensure the safe supply of cobalt mineral resources in China.
