摘要
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。
The role of gaseous phase in the formation of hydrothermal ore deposits is a question which has been mentioned for a long time, but it was not paid enough attention to in the study of deposits.This paper discusses the role of gaseous phase from both the gaseous phase transport of ore metals and the effect of gas liquid phase transform on the forming of ore deposits. It is pointed out that there exists Rely fractionation of hydrogen and oxygen isotopes in the forming process of hydrothermal ore deposits because of gas liquid phase transform. The effect of isotope fractionation due to gas liquid phase transform in the forming of ore flow must be considered when the hydrogen and oxygen isotopes are used to trace the origin of ore flow.
