| 中文摘要: |
| 早、晚二叠世之间大规模峨眉山玄武岩喷发是峨眉地幔热柱基性岩浆活动的高峰期.峨眉山玄武岩在贵州西部地区广泛分布,它不仅以矿源层形式参与钼、铜、铅、锌、金、锑、汞、铊等以地下水热液成矿作用为主的层控矿床的形成,而且它自身形成火山气液型矿床--玄武岩铜矿及伴生热液型铂、钯等矿化点;再者它是外生矿床--高砷煤、高氟煤、高硫煤、高汞煤形成的主要原因. |
| 英文摘要: |
| Large scale eruption of Emeishan basalt between early and late Permian took place in the summit of basic magma activity of Emei mantle plume. Emeishan basalt is greatly contributed in the western Guizhou province. Emeishan basalt not only partook in formation of stratabound deposits like Mo, Cu, Pb, Zn, Au, Sb, Hg and TI which were formed by groundwater ore forming fluids in form of source bed, but also leaded to form volcanic hydatopneumatogenic deposits or basalt type copper deposits and associated hydrothermal Pt and Pd mineralizing point. Moreover, it is a main reason for the formation of some exogenic deposits like As - high, F - high, S - high or Hg - high coal. |
