摘要
热液作用是金矿化中极其重要的机制，金在热液中的存在形式具有十分重要的地质意义。自然界中金元素主要呈金属态存在，而且其粒度极为细小，在自然环境中几乎没有化学反应能将其离解成离子状态，人工合成的金络合物在地质环境中基本未被发现，说明金难以以络合物的形式存在于热液中。根据许多地质现象及“纳米效应”推断金在热液中可能主要呈金属态存在。
Hydrothermal process is important for gold metallization. It is important significancethat study being formal of gold in hydrothermal fluid．The most of discovered gold is nativein natural world，and the size ranges is microfine or ultramicrofine．Gold can’t be ionized bychemical reaction in natural．Synthetic gold complex is not finded in many geological circum-stances．This paper proves that gold may be native in hydrathermal fluid on the basis of geo-logical facts and nano－effects.
