| 摘 要： | 富碲化物型金矿具有自然金成色高的特点，通过热力学分析，推导出碲逸度与温度和自然金中银含量的关系式，建立了ｆＴｅ２－Ｔ－ＮＡｇ图解，并论述了该类型金矿中高自然金成色的内在原因，即成矿溶液中高的碲逸度导致了高的自然金成色，同时也分析了溶液中碲逸度对金银矿物的共生组合的影响，以及对如何计算成矿溶液中碲逸度问题进行了讨论。

| Abstract: | The high fineness of native gold exists among tellurides rich type of gold deposits On the basis of thermodynamics analyses, the relationship among tellurium fugacity, temperature and fineness of native gold and the diagram of f Te 2 - T - N Ag , which indicates the interor reason leading the high fineness of native gold in this type of gold deposits, are constructed The problems about the influence of tellurium fugacity on gold silver mineral assemblages and how to calculate the tellurium fugacity in mineralization solution are discussed |
