摘　　要：钴是一种战略金属,具有诸多优良的理化性能,广泛应用于航空、航天、汽车和电池等领域。山丹县骆驼脖子钴铁矿原为赤、褐铁矿点,经进一步勘查,钴元素明显富集,伴生钴品位为0.018%~0.194%。以山丹县骆驼脖子钴铁矿为研究区,综合分析成矿地质背景、矿区地质特征及矿床特征,明确矿床成因。矿区位于龙首山西段,矿体严格受构造控制,矿液沿断裂运移、沉淀和富集。作为矿体顶板,石英千枚岩具有隔挡作用,使矿液沿断裂有利部位沉淀成矿,矿床成因类型为断裂构造控制的热液充填型。Cobalt is a strategic metal with many excellent physical and chemical properties,widely used in fields such as aviation,aerospace,automobiles and batteries.The Luotuobozi cobalt-iron ore in Shandan county is originally a red and brown iron deposit,after further exploration,the cobalt element is significantly enriched,and accompanying cobalt grade is 0.018%~0.194%.Taking the Luotuobozi cobalt-iron ore in Shandan county as the research area,a comprehensive analysis of the geological background of mineralization,geological characteristics of the mining area,and deposit features is conducted to clarify the genesis of the deposit.The mining area is located in the western section of Longshou Mountain,and the ore body is strictly controlled by tectonics,and the mineral fluid migrates,precipitates and accumulates along faults.As the roof of the ore body,quartz phyllite has a barrier effect,allowing mineral fluids to precipitate and deposit along favorable fault locations,and the genesis type of the deposit is hydrothermal filling controlled by fault structures.
