摘要
在内生作用中金与银既有共生的一面 ,又有分离的一面。其共生与分离受地球演化历史制约 ,受控于元素化学性质和地球化学亲和性 ,与岩浆起源、演化有关 ,受控于不同的基底建造和构造单元。成矿作用中金与银的共生与分离可用Au/Ag比值大小来衡量 ,本文提出了根据Au、Ag的地壳克拉克值和工业品位对传统的Au/Ag比值进行校正的方法 ,校正后的Au/Ag比值可有助于矿床研究。
Gold is not only associated with silver, but also separated from silver in the metallogenic processes. Their paragenesis and separation are controlled mainly by the evolution of the earth and chemical properties, geochemical affinity, basement formation, origin and evolution of magmatic rocks and the characteristics of tectonic units. The extent of paragenesis and separation can be measured in terms of Au/Ag ratios which can be used for prospecting and evaluating mineral resources.\;
