The Baishiding molybdenum deposit is located in northern Guangxi, and its ore bodies occur mainly as quartz+molybdenite veins in Guiling biotite monzogranite and epimetamorphic neritic facies clastic rocks in Nanhua System. Ore minerals are composed of molybdenite, pyrite, chalcopyrite and scheelite. The Mo grade ranges from 0.1% to 0.3% with an average of 0.12%. Zircon SHRIMP U-Pb dating of Guiling biotite monzogranite shows that the granite was emplaced at (424. 4±5. 6) Ma, whereas the zircon from the enclave has an age of (428±4) Ma. These data suggest that the Baishiding molybdenum deposit was formed in Silurian, implying that Mo mineralization did occur in Silurian in South China.
