江西省盘古山钨矿是南岭地区较为典型的石英脉型钨矿，为典型的“五层楼”模式矿区。矿区发育石英闪长玢岩和玄武玢岩两种岩脉。通过岩脉的地球化学研究和锆石LA-MC-ICPMS U-Pb定年研究，获得了该矿区石英闪长玢岩和玄武玢岩脉的同位素年龄，分别为（156.82±0.82）Ma（MSWD=1.06）和（76.93±0.47）Ma（MSWD=0.72）。该数据的成果与矿区的辉钼矿成矿年龄和隐伏花岗岩的U-Pb年龄对比显示，石英闪长玢岩是成矿期的岩浆活动，且与隐伏花岗岩为同期产物，可能对该区钨矿成矿作用起到一定的作用，而玄武玢岩脉则是成矿后的岩浆活动，对矿床起到破坏作用。

Pangushan tungsten deposit located in Nanling area, is a typical quartz vein-type ore, which is characteristic of the so-called"Five-floored"ore type. The mining area develops quartz diorite porphyrite dike and basaltic porphyrite dike. The ages for the quartz diorite porphyrite and basaltic porphyrite were obtained, (156.82 ± 0.82) Ma (MSWD=1.06) and (76.93 ±0.47) Ma (MSWD=0.72) respectively, by studying the geochemical characteristics of the dykes and Zircon LA-MC-ICPMS U-Pb dating. The results of data compared with data of the molybdenite metallogenic age and concealed granite U-Pb age show that the quartz diorite porphyrite is derived from the Metallogenic period of magmatic activity, which is of the same period as the concealed granite product. It may be related to the area of tungsten mineralization. While the basaltic porphyrite dykes is after the ore-forming magmatic activity, which had the damage effect to the deposit.
