摘要 本文以西华山钨矿为例,介绍了用水/岩交换氢氧同位素地球化学行为特征,判定热液矿床成矿介质水的性质、来源及各种水/岩交换初始参数的确定方法;阐述了经水/岩交换后成矿热液水与其初始水之间氢氧同位素组成的差异;指出要慎重使用混合水成矿的观点来解释矿床成因. The Xihuashan W-deposit is taken as an example in this paper to illustrate that the nature andorigin of ore-forming medium of a hydrothermal deposit, and initial parameters for different water-rockexchang may be determined in the light of hydrogen-oxygen isotope geochemical behaviour during theexchange between water and rock. The difference in hydrogen and oxygen isotope compositions betweenthe ore-forming hydrothermal solution and initial water after the water-rock exchange has been expounded. To explain the genesis of a deposit with mixing water viewpoint has to be done with great care.
