... succession was previously established by Tanelli (1982) , providing a common chart for the Piaotang and Xihuashan deposits. According to Tanelli (1982) , the succession can be divided into three stages: (1) a first “oxide stage” with quartz, K-feldspar, beryl, topaz, wolframite, and cassiterite; (2...

... developments of rare metal mineralization are closely related to Mesozoic granitic magmatism ( Mao et al. 2013a ). Mesozoic granitoid and volcanic rocks are widespread in the South China Block, and the large tungsten deposits (e.g., the Dajishan W deposit, the Xihuashan W deposit, and the Piao-tang W–Sn...
