| 摘 要： | 位于川-滇-黔铅锌多金属成矿域中南部云南会泽超大型铅锌矿床可能是一种新的铅锌矿床类型，该类铅锌矿床明显特征是规模大、品位富、伴生有用元素多，暗示其成矿环境较为特殊。从成矿时代、成矿物质来源、成矿流体来源与演化，以及峨眉山玄武岩与成矿的关系等方面分析了会泽超大型铅锌矿床的研究进展及国内外研究现状，认为矿床成矿时代与西南大面积峨眉山玄武岩成矿时代相近，成矿物质和成矿流体具有“多源性”，成矿流体存在均一化过程，区域大规模流体运移在该区铅锌成矿过程中具有重要意义，峨眉山玄武岩岩浆活动与铅锌成矿具有密切的成因联系，矿床可能为“均一化成矿流体贯入成矿”的产物。 |
| 关 键 词： | 铅锌矿床 成矿流体 玄武岩 矿床成因 矿床特征 |

| Abstract: | The Huize superlarge zinc-lead deposit, which is located in the center of the Sichuan-Yunnan-Guizhou Zn-Pb polymetallic mineralization zone, may be a new type of Zn-Pb deposit. This type of Zn-Pb deposits is famous for their large scale, high grade and many associated trace elements. These characteristics imply that they may form in a special setting. In this paper, based on the metallogenetic age, the source of base metals and ore-forming fluid and the relationship between the Emeishan basalt and mineralization, we summarized the progress in the study of the Huize superlarge Zn-Pb deposit. The result showed that the age of this deposit is close to that of the Emeishan basalt that is distributed in Southwest China. The base metals and ore-forming fluid have several sources, which were completely mixed during leaching, migration and precipitation processes. Large-scale fluid migration in this area played an important role in Zn-Pb mineralization. Zn-Pb mineralization in this area is closely connected with Emeishan basalt magmatic activities. When homogenous fluid migrated on a large scale in host carbonate rocks, Zn-Pb ores were precipitated. |
