摘　　要：古台山金锑矿床是湘中地区重要的中型金锑矿床,属与岩浆活动有关的破碎带型金锑矿床。为厘清3号金锑矿脉的地质特征及找矿方向,在分析矿山地质资料的基础上,开展了坑道调查、钻探验证、岩矿测试、地球化学等研究工作。研究结果表明,江口组为矿源层,区域变质作用、岩浆热液活动和构造运动使矿源层中的成矿元素活化,进入成矿流体并随之迁移,在适宜的容矿构造中富集成矿;矿脉在垂向上分带性明显,具阶梯式侧伏,侧伏角约70°;预测了2个找矿靶区,在Ⅰ号找矿靶区施工了4个钻孔,均见到了工业矿体,表明矿区深部具有很好的找矿前景。The Gutaishan gold-antimony deposit is an important medium-sized gold-antimony depos⁃it in central Hunan,which belongs to the type of broken zone related to magmatic activity.In order to clarify the geological characteristics and prospecting direction of No.3 gold-antimony vein,based on the analysis of mine geological data,the research work of tunnel survey,drilling verification,rock and ore testing and geo⁃chemistry has been carried out.The results show that the Jiangkou Formation is a source layer,and the ore forming elements in the source layer are activated by regional metamorphism,magmatic hydrothermal activi⁃ty and tectonic movement,which enter the ore-forming fluid and migrate with it,and then enrich the ore forming in the suitable ore-bearing structure.The vein is obviously zoned in the vertical direction,with a stepped side,and the side Angle is about 70°.Two prospecting targets have been predicted,and four bore⁃holes have been drilled in No.1 prospecting target,and industrial ore bodies have been seen in all of them,indicating that the deep mining area has a good prospecting prospect.
