7. Conclusions
- (1)
- Both the granite porphyry and the monzonitic granite porphyry, related to the Leimengou Mo mineralization, yield the LA-(MC)-ICP-MS zircon U–Pb ages of 131 ± 0.6 Ma (MSWD = 1.6), which is consistent with the molybdenite Re–Os age of the Leimengou deposit. The age is also consistent with the petrogenesis age of the Huashan granite batholith.
- (2)
- The whole rock geochemistry and zircon Lu–Hf isotopic indicate that the source material of the Leimengou intrusion is mainly from the ancient continental crust, likely the Archean Taihua Group, with a small amount of mantle-derived components.
