| 中文摘要: |
| 船场铅锌多金属矿区位于福建上杭—云霄金银铜铅锌钨钼成矿带。矿区内花岗斑岩为钙碱性系列,具高硅、高铝、高碱、富钾的特征；花岗斑岩稀土元素总量高,且富轻稀土,并具有明显的负铕异常,稀土元素标准化分布型式为右倾V型,与A型花岗岩具有相似性。花岗斑岩体中Pb、Zn、W、Mo等成矿元素含量,高于中国花岗岩中的平均值的2～6倍。矿区内Pb、Zn等成矿与花岗斑岩有着密切的成因联系,岩浆活动为矿区内Pb、Zn等成矿提供了必要的热源和物源条件。 |
| 英文摘要: |
| The lead-zinc polymetallic ore in Chuanchang is located in the Shanghang-Yunxiao gold-silver-copper-lead-zinc-tungsten-molybdenum (Au-Ag-Cu-Pb-Zn-W-Mo) metallogenic belt in Fujian Province. Granite porphyry is the calc-alkaline series in the mining area, featured with high silicon, high aluminum, high alkali and rich potassium. The amount of rare earth element is high in the granite porphyry, with rich light rare earth and depleted heavy one. Besides, there has obvious negative europium anomaly, and the standard distribution pattern of rare earth element is the right-oblique V-shape, similar to that of A-type granite. The content of metallogenic elements such as Pb, Zn, W and Mo in the granite porphyry is as twice-six times as high as the average content in the granite in China. The mineralization of Pb, Zn and so forth for which the magmatic activity provides necessary heat source and provenance has a close genetic relationship with granite porphyry in the mining area. |
