摘要
成矿热液的氢、氧同位素组成既取决于组成热液的不同成因介质水的初始氢、氧同位素组成．又受介质水演化过程中氢、氧向位素组成变化的影响。本文通过月山地区铜矿床成矿热液氢、氧同位素组成五种演化机理的讨论．构筑了成矿热液的δ１８Ｏ－δＤ综合模式图．并确定了铜矿床成矿热液的来源。
The hydrogen and oxygen isotope compositions of ore-forming fluids depend not only on the initial hydrogen and oxygen isotope commotions of different waters that form the ore -forming fluids, but also on the hydrogen and oxygen compoistional variation of different waters in the process of evolution. In this paper five δ18O-δD isotopic evolutional mechanisms have been fully studied and a δ18O-δD synthetic map has been constructed. Finally,the origins of oreforming fluids in copper deposits in Yueshan district are determined.
