Trace elements, U–Pb ages and Hf isotopes of zircons from Mesozoic granites in the western Nanling Range, South China: Implications for petrogenesis and W–Sn mineralization

The E-W trending Nanling Range, located in the southern part of the South China Block (SCB), is characterized by widespread intra-continental Mesozoic granitoids and accompanying W–Sn polymetallic ore deposits. Detailed studies are presented on trace elements, U–Pb ages and Lu–Hf isotopes in zircons from the Mesozoic A2-type like granitoids (including the Qianlishan, Qitianling, Xianghualing, Huashan, Guposhan, Niumiao, Tong'an, Jinziling and...
