摘　　要：钴是全球战略性关键矿产,对国民经济、国家安全和科技发展不可或缺。中国现有钴资源储量较低,超过98%的钴原材料依赖进口,给国家战略性关键矿产资源供应带来重大安全隐患。因此,立足国内加强钴矿成矿规律认识、寻找新的资源接续区已迫在眉睫。西北地区钴矿资源禀赋条件优越,拥有较好成矿地质条件和资源潜力,展示了巨大的找矿前景。但目前不同类型矿床中钴矿发育特征、赋存状态、富集机制与成矿潜力尚不明确,缺少针对性的找矿模型与高效的勘查技术方法,极大地制约了钴资源的找矿新发现。笔者通过西北地区钴矿资源地质分布、成矿特征、控矿条件、找矿标志、找矿潜力的系统梳理,总结西北地区钴矿资源禀赋特征,结合钴矿资源产业链、供应链安全,分析提出西北地区钴矿资源进一步找矿方向和勘查重点,旨在揭示钴矿资源成矿潜力和找矿新靶区,支撑服务新一轮找矿突破战略行动,引领中国钴矿资源找矿新发现,提升钴矿资源安全供应和保障能力。Cobalt is a global strategic critical mineral resource,which is of great strategic significance to the national economy,national security,and technological development.More than 98%of cobalt raw materials rely deeply on imports due to its scarcity in China,which brings major security risks to the supply of national strategic key mineral resources.Accordingly,it is urgent to strengthen the study of cobalt metallogenic regularity and to identify the new resource supply areas.Favorable cobalt resource endowment is recognized in Northwest China,possessing well ore-forming geological conditions and resource potential,exhibiting promising exploration prospects.Nevertheless,the development characteristics,occurrence state,enrichment mechanism,and metallogenic potential of different types of cobalt deposits remain unclear.Also,the lack of targeted prospecting models and efficient exploration techniques greatly hinders the discovery of new cobalt resources.Based on a comprehensive review encompassing the geological distribution,metallogenic characteristics,ore-controlling conditions,prospecting indicators as well as industrial chain and supply chain security considerations related to cobalt resources in Northwest China,this paper summarizes the cobalt resource endowment and proposes further prospecting target and exploration focus in this region.The research aims to uncover metallogenic potential and identify new prospecting targets for cobalt resources,support strategic mineral prospecting operations,lead the new discovery of cobalt resources,and enhance the capacity of safe supply and guarantee capability of cobalt resources.
