【摘要】 同位素方法已广泛用于矿床成因研究：确定矿床的形成年代，研究含矿热液的来源和地质过程。但是针对具体矿床，这方面研究仍存在许多不确定性或多解性。湘西南石英脉型金矿的成矿流体来源，是一个颇有争议的问题，有人认为成矿流体主要有变质水，后期可能有大气降水加入［...更多还原

【Abstract】 Water—rock interaction in conjunction with the isotopic study of strontium,hydrogen and oxygen is introduced using the model calculating methods for ore forming fluids.The quartz vein type gold deposits in the southwestern Hunan Province are taken as examples to illustrate the nature and origin of ore forming medium of hydrothermal ore deposits.The results of different water—rock exchanges using the model calculating methods are interpreted.It is proposed that great ores should be taken in interpretating genesis of ore deposits with δD δ 18 O diagrams.更多还原
