摘要
马山金矿床是在著名的铜官山铜矿田内发现的一个独立的金矿床。地质及地球化学研究初步表明该矿床具有“两型一体”特点,即既有岩浆热液沿层间构造断裂的充填—交代型矿体,也有在黄龙组白云岩段底部的原始沉积黄铁矿层基础上的叠加—改造型矿体。二者在物质组份、微量元素、稀土元素、总硫同位素组成以及矿石结构、构造、矿体产状等许多方面明显不同。
Mashan geld deposit,discovered recently in the famous Tongguanshan copper field, is characterisedby“binary”.One type is filling-metasomatic typefilling in detachment fault belts or fissures of wall rocks and another is telesooping -modificating type occurred on the basis of sedimentary pyrite beds located at the bottom of dolomite strata of Huanglong Formation.There exist distinct differences between the two types in such aspects as component,trace element,rare earth element,total sulfur isotope ore texture and structure and occurrence of ore bodies et al.
