【摘要】 系统地研究了脉石矿物方解石中流体包裹体特征及矿床的水岩反应条件。研究结果表明,该矿床的形成与中低温热液与中高温热液的混合有关;成矿流体的H、O同位素组成在不同矿体中没有明显的差别,流体形成前曾存在流体的均一化作用;成矿流体的形成是地层循环水与变质水、岩浆水在流体储库中充分混合的结果。因此,成矿流体具有多源性。更多还原

【Abstract】 The characters of fluid inclusions in calcite and water-rock reaction of the ore deposits was systematical studied.It is suggested that the ore deposit under study was relative to the mixing of the low-temperature and high-temperature hydrothermal solutions.δ¹⁸O and δD values of ore-forming fluid of different ore bodies are unanimous,thus indicating that fluid homogenisation once happened before the formation of ore-forming fluid.The ore-forming fluid in fluid reservoir is of multiple derivation of the mixed circular waters in the strata,metamorphic fluids and magmatic waters.更多还原
