Tungsten and tin deposits in South China: temporal and spatial distribution, metallogenic models and prospecting directions

•Types and temporal-spatial distribution of W and Sn mineralization in South China are summarized based on over 130 major deposits.•Metallogenic models illustrating the combination of diverse mineralization styles or metal assemblages are proposed for W-Sn deposits in South China.•Fluid and melt inclusion compositions are tested as new index to evaluate W and Sn mineralization potential in granitic system.
