自然金的化学成分是其形成条件的最重要的标志。自然材料的研究及实验资料表明,金的成色除取决于溶液中金和银的浓度比以外,还取决于其他许多因素,包括热液温度、氧化还原条件、酸碱条件和热液阴阳离子成分等参数。成矿沉积时的温度条件基本上决定了金银元素的类质同象混溶性和金-银系列矿物的成色。同时,温度还以各种方式影响着不同成分的溶液中各金属元素的沉淀和结晶的动力学特征。目前,解决自然金成分与其沉淀温度相互
The chemical composition of natural gold is the most important symbol of its formation conditions. Natural materials research and experimental data show that, in addition to depending on the fineness of the gold in the solution concentration ratio of gold and silver, but also depends on many other factors, including hydrothermal temperature, redox conditions, acid-base conditions and hydrothermal anion and cation components Other parameters. The temperature conditions during mineralization basically determine the isomorphous miscibility of the gold and silver elements and the fineness of the gold-silver series minerals. At the same time, the temperature also affects the kinetic characteristics of precipitation and crystallization of the various metal elements in solutions of different compositions in a variety of ways. At present, the solution of natural gold components and their precipitation temperature mutual
