热液成矿是一个由热液腐蚀变化之后形成的矿物组合,其中能够反映出成矿流体的一个地球化学的显著特征,在整个的蚀变状态中有着非常关键的寻找矿物的勘测性价值。在整个的热液形态中,金是主要的运行移动形式载体,热液的体系温度和压力以及其他的一些条件都是能够使金的运行形式被隔离,金会不断沉淀。从金矿的热液形成机制中,不断在硫逸度比较低的状态下形成了自然金的组合形态,金也会向热液的蒸汽方面靠拢。热液中的金在沉淀之后所形成的状态是要以显微或固溶的方式附着在硫化矿物中,这些矿物也会受热液的具体活动性质来管控。 Hydrothermal mineralization is a mineral assemblage formed after hydrothermal alteration. It can reflect a geochemical salient feature of ore-forming fluids and has a very crucial value in the whole alteration of the ore-searching potential. In the hydrothermal configuration as a whole, gold is the main carrier of the mobile form of movement. The temperature and pressure of the hydrothermal system and other conditions are such that the gold form of operation is isolated and the gold deposits. From the hydrothermal formation mechanism of the gold mine, a combination of natural gold is continuously formed in a state where the sulfur fugacity is relatively low, and gold also moves closer to the vapor of hydrothermal fluids. The formation of gold in the hydrothermal solution after precipitation is to be attached to sulphide minerals in a microscopic or solution-like manner. These minerals are also governed by the specific activity of the hydrothermal solution.
