气相成矿作用是人们早已注意的问题 ,但在矿床学研究中没有给予应有的重视。文章从金属成矿物质的气相迁移、气 -液相转变对成矿的作用初步探讨了气相成矿作用问题。提出热液矿床成矿过程中必然存在由于气 -液相转变而产生的氢氧同位素瑞利分馏 ,在应用氢氧同位素示踪热液成矿流体来源时必须考虑成矿流体气 -液相转变引起的同位素分馏效应 ,只有这样才能正确示踪成矿流体的来源 ,合理分析热液矿床的成矿机制。
Gas-phase mineralization is a problem that people have long been concerned about, but no proper attention has been given to deposit mineralogy. In this paper, the gas-phase mineralization is discussed from the gas migration and gas-liquid phase transition of metallogenic material to metallogenesis. It is proposed that the hydrothermal isotope Rayleigh-Fractionation due to the gas-liquid phase transformation must exist in the mineralization process of hydrothermal deposits. When the source of hydrothermal ore-forming fluids is to be traced using hydrogen and oxygen isotopes, the gas-liquid phase transformation of ore-forming fluids must be considered Caused isotope fractionation effect, the only way to correctly trace the source of ore-forming fluid, a reasonable analysis of hydrothermal mineralization mechanism.
