| 摘 要： | 东峰顶金矿主要赋存于近SN向断裂破碎带中，呈脉状产出。矿石类型主要为硫化物（黄铁矿）-石英金矿石、褐铁矿-石英金矿石、褐铁矿金矿石等，矿石氧化率达86．2％，氧化矿石含金量高，以中粗粒表生自然金为主。成矿分原生热液成矿期和表生成矿期，原生热液成矿期具多阶段性，表生成矿期使金进一步富集。包裹体、铅和硫同位素、原生金成色以及黄铁矿中微量元素等特征研究表明：成矿溶液以岩浆水为主，可能混有地下热卤水，是一种低盐度、中低密度的流体，成矿物质来自于基底老变质岩（矿源层），成矿温度在148℃～395℃之间，矿床形成距今年龄值约100Ma左右，属中温、中深岩浆热液型金矿床。矿床形成过程为：矿源层中金的活化-热液中金的迁移、沉淀-表生作用下金的再富集。 |

| Abstract: | The veins of the Dongfengding gold deposit occurs in north-south faults.The main ore type is pyrite-quartz gold ore,limonite-quartz gold ore and limonite gold ore.The ore oxidation rate is up to 86.2%.With high gold content,oxidized ore is characterized with natural gold.The mineralization stage is composed of primary hydrothermal mineralized period and surface mineralized peroid.Primary hydrothermal mineralized period have many steps and gold is further centralized in surface mineralized period.The studies... |
