摘要
刘家坪黄铁矿型块状硫化物铜-锌矿床是一个面临闭坑的矿山。对矿区刘家坪组火山岩机构的研究,将是进一步寻找矿体的关键。通过野外地质调查及对刘家坪铜-锌矿区刘家坪组火山岩系的岩石矿物组合和结构构造、岩石化学成分、稀土元素地球化学特征的研究,初步确定了矿区古火山机构及其岩相构造的基本特征,建立了火山岩层序、喷发旋回和喷发类型。
Liujiaping pyrite type massive sulfide copper （zinc） deposits would be shut in. Studying the volcanic apparatus of Liujiaping Formation is the key to further exploralion mass of copper （zinc） ore in Liujiaping mining area. By field investigation, and based on the rock and mineral constitute and its texture of Liujiaping Formation volcanic rock system, the chemical composition and REE geochemical characteristics, the volcanic apparatus and basic characteristics of the petrographical facies texture of Liujiaping mining area are preliminary ascertained. The volcanic rock sequence, eruptive cycle and eruptive type are builded.
