New precise zircon U-Pb and muscovite 40 Ar- 39 Ar geochronology of the Late Cretaceous W-Sn mineralization in the Shanhu orefield, South China

The Shanhu orefield, located in the northeastern Guangxi province, is an important part of W-Sn polymetallic metallogeny in the Nanling region. The Shanhu W-Sn deposit is spatially associated with the Yantianling granite. LA-ICPMS zircon U-Pb dating of the Yantianling granite yields Late Cretaceous ages of 100.9 ± 2.2 Ma and 100.8 ± 2.3 Ma. Hydrothermal muscovite 40Ar/39Ar dating yields plateau ages of 102.7 ± 1.7 Ma and 100.8 ± 0.7 Ma. This...
