摘要: 文章通过对太和仙金多金属矿区地层、构造、岩浆岩、矿体特征等的综合研究与分析,认为该矿区矿源层分布广泛,成矿构造条件优越,成矿序列明显,矿床属岩浆热液成因的破碎带蚀变岩型金多金属矿床,并以此为基础,建立了太和仙矿区破碎带蚀变岩型金多金属矿的成矿模式;重力异常特征、水系沉积物异常特征显示矿区处于隆起的热液活动区,下伏可能存在一隐伏岩体。推测太和仙矿区找矿潜力大,可作为寻找中大型以上规模金多金属矿床的有利地段。Abstract: Through comprehensive research and analysis on the characteristics of the stratum, structure, mag-matite and mineral vein in Taihexian gold polymetallic ore deposit, Eastern Hunan Province, we believe that the ore source bed is widely distributed, tectonic condition is superior, metallogenic series is clear, and the deposit belongs to fracture zone alterated rocks type forming from magmatic hydrothermal solution, based on these, we built the metallogenetic model for gold polymetallic deposit of fracture zone alterated rocks type in Taihexian area. In addition, the characteristics of gravity anomaly and stream sediment anomalies shows that the orefield is located in the uplift zone with hydrothermal activities, there may be a hidden intrusion under it. In summary, we infer that the Taihexian orefield is the favorable location for large scale gold polymetallic deposit with great prospecting po-tential.
