有色金属大部分来自热液硫化矿床.深入研究硫化矿床成矿特征、成矿规律,尤其是硫化矿床的共同组份——硫,在岩浆热液中的存在形式及其与成矿的关系是很有意义的.这不仅是矿床领域,而且也是地球化学范畴中尚未解决的一个理论问题. 在指导找矿勘探中,现有的热液硫化矿床的成矿理论起过很好的作用.但随着地质勘探和研究工作的不断发展,这种理论远不能解释硫化矿床成矿的若干过程.例如,关于成矿溶液的性质,一直认为它是一种含成矿组份很稀薄的溶液,所有成矿组份都溶解在溶液中,随温度、压力及其他物理化学条件的改变,硫化物就逐步沉淀下来
Most of the non-ferrous metals come from hydrothermal sulphide ore deposits. In-depth study of the mineralization characteristics and metallogenic regularity of sulphide ore deposits, especially the common component of sulphide ore deposits, the existence of sulfur in magmatic hydrothermal fluids and its relationship with metallogenesis This is not only a field of deposits but also an unresolved theoretical issue in the geochemical field that has played a very good role in guiding the mineralization of hydrothermal sulphide deposits in prospecting exploration With the continuous development of geological exploration and research work, this theory can not explain the process of mineralization in sulphide ore deposits .For example, regarding the nature of ore-forming solution, it has been considered that it is a very thin solution containing metallogenic components, All metallogenic components are dissolved in the solution, with the temperature, pressure and other physical and chemical conditions change, the gradual precipitation of sulfide
