The Xihuashan and Tieshanlong tungsten deposit is an important large quartz vein‐type W‐polymetallic deposit in the southern Jiangxi Province, eastern Nanling Range. Zircon U–Pb analyses of representative ore‐forming granites from the Xihuashan and Tieshanlong tungsten deposit yield ages of 146.3 ± 2.9 Ma and 146.0 ± 3.8 Ma, respectively. According to the zircon Raman spectroscopy, these granitic rocks are disturbed by different degrees of hydrothermal alteration, whereas most zircons exhibit primary oscillatory zoning and Th/U ratios in the range of magmatic zircon, which means the analysis results represent the crystallization age of metallogenetic granitic assemblages. In combination with regional geological data, it is suggested that the Late Jurassic is probably another important episode of granitic magmatism and W‐Sn mineralization in southern Jiangxi Provinces, even South China.

西华山和铁山龙矿床花岗岩中锆石的U–Pb年代学和拉曼光谱：对江南南部W-Sn矿化的启示

西华山和铁山龙钨矿床是江西省南部，南岭山脉以东的重要的大型石英脉型W多金属矿床。西华山和铁山龙钨矿床中代表性的成矿花岗岩的锆石U-Pb分析结果分别为146.3±2.9 Ma和146.0±3.8 Ma。根据锆石拉曼光谱，这些花岗石受到不同程度的热液蚀变的干扰，而大多数锆石在岩浆锆石的范围内表现出主要的振荡带和Th / U比，这意味着分析结果代表了成矿花岗岩的结晶年龄。的集合。结合区域地质数据，
