| 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. |
