| 摘 要： | 三山岛金矿位于胶东西北部,属于典型的破碎蚀变岩型金矿。流体包裹体研究表明该矿床为中温、中低盐度H2O-CO2-NaCl±CH4流体;中深部成矿流体对比研究表明,在纵深超过2000m范围内,成矿流体具有较一致的成矿流体介质条件,主成矿均一温度为170~330℃,成矿压力为50~255MPa。H、O、C同位素表明,深源流体参与了成矿作用,很可能是与金矿床伴生的基性幔源岩浆脱水形成的岩浆水,在地壳浅部遭受到大气降水的混合,而S同位素研究进一步揭示了成矿物质具有多源性,矿区浅表在成矿晚期可能受到了表生硫影响而导致δ34S偏高。水岩反应、成矿应力场转变及表面吸附电化学还原反应等导致金沉淀成矿。
