Similarly, wolframite dating from W-deposits is also missing owing to the lack of suitable techniques for precisely dating both the hydrothermal deposits and associated granitoids. Nevertheless, direct U–Pb dating of wolframite chronology by TIMS and LA-ICP-MS has been performed in the past few years (e.g., Harlaux et al., 2018a and b; Deng ...
