| 摘 要： | 排山楼金矿床赋存于太古宙建平群东西向韧性剪切带之中。强蚀变糜棱岩即为金矿体及金矿化体。载金矿物为沿糜棱面理分布的细粒黄铁矿、动态重结晶石英集合体及铁白云石。金矿体直接受黄铁矿—黑云母化蚀变带控制。金的赋存状态以晶隙金为主,其次为少量黄铁矿包裹金。金矿化具有不同构造期的特点。金与微量元素的相关性,铅同位素及稀土元素特征都说明金来源于太古宙建平群变质岩。为同韧性剪切带型金矿床。

| Abstract: | Paishanlou gold deposits occurred in WE-trench ductile shere zone in Jianping Group of Archaeozoic. Strongly altered mylonite is gold orebody and gold mineralized body. Gold carrier minerals are fine-grained pyrite, recrystallized quartz aggregates, and ferrodolomite along foliations of mylonite. GqIcI orebodies are directly controlled by pyritization and biotite alteration zones. Gold mainly enriched in crystal interstices and cracks, secondly in pyrite. Its mineralization is syntectonic. The correlation of gold and trace elements, the characteristics of lead isotopes and rare earth elements all show that gold was derived from metamorphic rocks in Jianping Group of Archaeozoic. |
