| 摘 要： | 玉海铜(钼)矿床成矿岩体为石英闪长(玢)岩,矿化呈细脉状、细脉-浸染状和稀疏浸染状。围岩蚀变主要为钾硅酸盐化、石英-绢云母化、青磐岩化和黏土化蚀变。矿床类型为斑岩型。铜(钼)矿化主要发育于钾硅酸盐化阶段、石英-绢云母化阶段和青磐岩化阶段。流体包裹体可划分为气液两相包裹体、含子晶三相包裹体和CO_2包裹体3种类型。钾硅酸盐化阶段的均一温度为307~423℃,盐度w(NaCleq)为4.18%~10.11%,密度0.62~0.77g/cm~3,属于高温、中-低盐度流体;石英-绢云母化阶段均一温度为172~336℃,盐度为w(NaCleq)为3.23%~8.55%,密度0.70~0.93 g/cm~3,属于中温、低盐度流体;晚期青磐岩化阶段均一温度155~296℃,盐度w(NaCleq)为3.71%~9.08%,密度0.80~0.96 g/cm~3,属于中低温、低盐度流体。从早阶段到晚阶段,成矿流体温度逐渐下降,各成矿阶段成矿流体盐度均小于11%,但钾硅酸盐化阶段成矿流体盐度稍高。石英-绢云母化阶段成矿流体δD=-91.6‰~-72.1‰,δ~(18)OH_2O=-1.8‰~6.3‰;青磐岩化阶段成矿流体δD=-97.1‰~-68.3‰,δ~(18)OH_2O=-6.3‰~2.2‰;成矿流体具有岩浆水和大气降水混合特征,但青磐岩化阶段大气降水含量更高。硫化物的δ~(34)S值为-3.5‰~2.8‰,硫来自石英闪长(玢)岩。
