| 中文摘要:盘古山钨铋矿床位于南岭成矿带东段的赣县-于都钨多金属矿集区，为一赋存于隐伏岩体外接触带的石英脉大型钨铋（碲）矿床。笔者采集了该矿区内2条不同地质产状黑钨矿-石英脉中的辉钼矿样品，进行了辉钼矿Re-Os同位素测试，获得其等时线年龄为（157.75±0.76） Ma （MSWD=0.99）和（158.8±5.7） Ma（MSWD=1.7）。测试结果显示，这2组矿脉是同一时期的成矿产物，均形成于燕山早期，属南岭EW向构造岩浆带作用的产物。 |

| Abstract:The Pangushan tungsten ore deposit is a large-size wolframite-quartz vein type W-Bi (Te) ore deposit in the exocontact zone of the buried rock body within the eastern part of the Nanling metallogenic belt. The authors collected molybdenite samples from the W-bearing quartz veins of different geological modes of occurrence. Re-Os isotopic dating yielded isochron ages of molybdenite (157.75±0.76) Ma (MSWD=0.99) and (158.8±5.7) Ma (MSWD=1.7). The ages indicate that these two mineralized veins belong to the same product and were formed in the same period, i.e., Early Yanshanian. The study also provides useful evidence that the ore deposit is the product of Nanling EW-trending tectonic-magmatic belt. |
