Zircon U-Pb ages of the two-periods magmatism from the Xiuwacu Mo-W-Cu deposit, northwest Yunnan, China

The Xiuwacu deposit is a large magmatic hydrothermal Mo-W-Cu deposit, and also a typical representative of the late Triassic mineralization in Geza Arc (Lai AQ et al., 2016;Liu XL et al., 2017). The Xiuwacu pluton intruded into the Lamaya Formation, and contains two periods of rocks bounded by intrusive contact. Nonetheless, most of the intrusive boundaries were superposed by later fault structures.
