斑岩铜矿床一向被认为是岩浆热液矿床。近年来,也有人将它划入火山热液矿床。多年来,人们对斑岩铜矿的形成条件和矿床成因作了大量的研究,但有关成矿金属来源的研究却很少。世界各地之热水和蒸气的氢氧同位素研究表明,95％以上的地热水(其中有的温度超过300℃,有的正在进行成矿作用)都是外生水。若“将今论古”,则有可能得出下列结论:地质历史上形成的多数热液矿床的成矿热液主要也是由外生水构成的。水是热液成矿过程
Porphyry copper deposits have always been considered magmatic hydrothermal deposits. In recent years, some people have classified it into volcanic hydrothermal deposits. Over the years, people have made a great deal of research on the formation conditions of porphyry copper deposits and the genesis of the deposit, but there are few studies on the source of metallogenic metals. Hydrogen and oxygen isotope studies of hot water and steam around the world show that over 95% of geothermal water, some of which are above 300 ° C and some of which are undergoing mineralization, is exogenous. If “Now on ancient”, then it is possible to draw the following conclusions: Most hydrothermal deposits formed in the geological history of the hydrothermal fluid is mainly composed of exogenous water. Water is a hydrothermal mineralization process
