| 摘要 | The Guposhan-Huashan district is an important W-Sn-Sb-Zn-(Cu) metallogenic area in South China. It is located in the middle-west segment of the Nanling Range. Granitoids in the Guposhan-Huashan district possess certain properties of A-type or I-type granites. The W-Sn-Sb-Zn mineralization in the district is closely associated with magma emplacement. Two igneous biotite and seven hydrothermal muscovite samples from skarn, veins and greisenization ores were analyzed by Ar-Ar methods. Two igneous biotite samples from fine-grained quartz monzodiorite and fine-grained biotite granite show plateau ages of 168.7 +/- 1.9 Ma and 165.0 +/- 1.1 Ma, respectively. Seven hydrothermal muscovite samples from ores yield plateau ages as two groups: 165 Ma to 160 Ma and 104 Ma to 100 Ma. These data suggest that the emplacement of fine-grained granitoids in this district is coeval with the main phase magma emplacement, different from previous studies. The W-Sn-Sb-Zn mineralization took place in two stages, i.e. the Middle-Late Jurassic and early Cretaceous. W-Sn mineralization in the Guposhan-Huashan district is closely related to the magmatism, which was strongly influenced by underplating of asthenospheric mantle along trans-lithospheric deep faults and related fractures. |
