| 摘 要： | 通过对典型金矿床的研究，作者将湖南益阳－沅陵金矿密集区内的金矿床分为单金、金－锑、金－钨和金－锑－钨四种类型，并分别阐述了不同类型金矿床形成的物理化学条件、成矿物质、成矿流体、成矿能量的来源，成矿元素活化转移和沉淀的机制。在对矿床地球化学特性进行系统研究的基础上，作者提出了区内金矿床的成矿作用，实际上是开放体系中低温水／岩反应过程的认识，并建立了相应成矿作用的地球化学模式。

| Abstract: | The gold deposits occurring in the Yiyang-Yuanling area are divided into four types: single Au, Au-Sb, Au-W and Au-Sb-W. This paper demonstrates the geologic-geochemical characteristics, ore-forming materials and fluids, and the mechanisrm for remobilization and precipitation of ore-forming elements, as well as the origin of energy for mineralization, of the gold deposits. The present systematic studies show that gold mineralization is a procedure of water/rock reactions in an open system with low temperatures. Finally, a geochemical model for gold mineralization is established. |
