摘　　要：姑婆山锡矿田原生锡矿床的成因类型有构造蚀变带型、构造蚀变岩-矽卡岩复合型和接触带矽卡岩型3种。通过对各类锡矿成矿地质条件、控矿因素和成矿规律的分析与总结,认为岩浆岩是控制各类型锡矿形成和分布的首要条件,区域性NE至SN向断裂(F1、F2)为导矿、控矿构造,其旁侧的次级断裂及岩体与地层的接触带为容矿构造;提出矿田西部和北部具有良好的找矿前景。Primary tin deposits of Guposhan orefield in Hunan Province include structural alteration zone type,structural alteration zone-skarn composite type and contact skarn type. In the light of analyses and summarization of metallogenic conditions,ore-controlling factorsand mineralization regularities,the authors believe that granitic magmatism is the key factor for tin mineralization,the NE- to SN-striking faults(F_(1)and F_(2)) and their secondary faults are ore-control and host structures,respectively. Study shows that the western and northern part of the orefield have excellent prospecting potential.
