摘要：The Jiangnan Orogen boasts abundant Neoproterozoic granitoids alongside locally significant W-Sn polymetallic mineralization in South China. However, the factors governing the relationships between granites and the W-Sn polymetallic mineralization remain elusive. Notably, Neoproterozoic W-Sn polymetallic mineralization locally occurred within the western margin of the Jiangnan Orogen, encompassing key deposits like the Jiumao, Huashadong, and Taoshulin deposits. The W-Sn-bearing Taoshulin muscovite granite intruded into Neoproterozoic Fanjingshan Group, comprising of low-degree metamorphosed sedimentary rocks that locally contain granitic gravel. These granites in this study have high SiO2 (73.6–77.4 wt.%), Al2O3 (12.8–15.1 wt.%), Na2O (3.16–5.25 wt.%) and high A/CNK values (1.28–1.47), which display co-variation trends. They have extremely low rare earth element (REE) concentrations ( ? 2024, The Authors. All rights reserved.
