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、找矿预测和资源评价等工作
In the endogenous role of both gold and silver symbiotic side, there are separate side. Its symbiosis and separation are controlled by the history of the Earth’s evolution and are controlled by element chemistry and geochemical affinity, which are related to the origin and evolution of magma and are controlled by different basement constructions and structural units. The symbiosis and separation of gold and silver in mineralization can be measured by the ratio of Au / Ag ratio. In this paper, a method of correcting the traditional Au / Ag ratio according to the crustal Clarke value of Au and Ag and industrial grade is proposed. The corrected Au / Ag ratios can be helpful for deposit research, prospecting prognosis and resource evaluation
