Muscovite 40Ar−39Ar age and its geological significance in Zhuxi W(Cu) deposit, northeastern Jiangxi

The Zhuxi W(Cu) skarn deposit, the world’s largest tungsten deposit is newly discovered in Jingdezhen city, northeastern Jiangxi province, China. It mainly occurs near the contact zone between the Yanshanian granites and the Late Paleozoic carbonate rocks. Three types of mineralization including skarn type, altered granite type and quartz vein-veinlet type orebodies have been observed. In this study, the 40Ar−39Ar age of hydrothermal muscovite...
