Geochemistry, zircon U-Pb geochronology and Hf-O isotopes of the Late Mesozoic granitoids from the Xiong'ershan area, East Qinling Orogen, China: Implications for petrogenesis and molybdenum metallogeny

•These granitoids were emplaced between 132 Ma and 127 Ma.•These granitoids derived from mixing of Taihua Group, Xiong’er Group and mantle.•The ore-bearing granite porphyry possesses higher fO2 than the ore-barren plutons.
