Genesis and magmatic-hydrothermal evolution of the Shapoling Mo deposit, East Qinling, China: Insights from geochronology, petrogenesis and fluid evolution

•Shapoling granitoids derived from a mixture of Taihua Group and mantle-derived components linked to lithospheric thinning.•The hydrothermal fluids shifted from early moderate- to low-salinity CO2-rich fluids, to late H2O-NaCl low-salinity fluids.•Formation of the Mo deposit is a result of the prolonged magmatic activity, with input of mantle-derived materials.
