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.
Abstract
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.
