| 中文摘要: |
| 对库布苏金矿北、中两个矿带含金石英脉样品内包裹体特征观察、均一温度测定以及流体成分的分析表明,含金石英脉成矿流体主要为气液两相包裹体,均一温度分为中低—中高两个区间,成矿流体成分不具有典型岩浆水与典型热卤水的特征;运用水岩反应的原理,在一定温度下结合不同W/R比,对成矿介质水内的氢氧同位素组成进行了计算,得到了与测试结果相近的δ(D)—δ(18O)组成,结合成矿流体不具有典型岩浆水和热卤水特征的事实,推测成矿流体可能为变质水或混合热液来源。 |

| On the basis of observing fluid inclusion characters of the vein quartz, measuring homogenous temperature, and analyzing compositions from Kubusu deposit, the paper drew the following conclusions: (1)the majority of fluid inclusions are consisted of two phases of vapor and liquor, (2)the homogenous temperature has two ranges-low-medium temperature and medium-high temperature, (3)the fluid inclusion compositions have nothing to do with the classic magmatic hydrothermal characters and the classic hydrothermal haloid's characters. Under guidance of water/rock reaction principle we calculated H,O composition of ore-forming media (water) and obtained the similar δ(D)-δ(18O) composition. The similarity, together with non classic magma and haloid character of ore fluid imply that the ore fluid is of metamorphic or mixed water. |
