在小南山含钨石英脉型钨矿床石英包裹体地球化学资料的基础上,我们对锡山矿床又做了进一步实验:采集了45个石英和6个花岗岩样品,分别进行了均一温度、包裹体成分(包括液相和气相)的测定。结果表明,矿脉中石英包裹体均一温度底部稍高于浅部,而元素总的变化趋势是矿脉底部低于顶部,尤其是CO_2。这些现象为地球化学找矿提供了重要线索。
Based on the geochemical data of quartz inclusions in the Xiaonanshan tungsten-bearing quartz vein tungsten deposit, we did further experiments on the Xishan deposit: 45 quartz and 6 granite samples were collected, and the homogenization temperature, (Including liquid and gas phase) determination. The results show that the homogenization temperature of the quartz inclusions in the veins is slightly higher at the base than at the shallow part, while the total elemental variation trend is that the bottom of the veins is lower than the top, especially CO_2. These phenomena provide important clues for geochemical prospecting.
