This paper discusses the late Yanshanian‐Himalayan igneous rock series and minerogenetic series (Cheng et al., 1979, 1982) related to tin polymetallic deposits in the Tengchong area. The multi‐stage differentiation and evolution of the igneous rock series led to the concentration of metal and ore‐forming elements in a cupola of a granite body formed in the late stage. The minerogenetic series shows a zoning of Nb‐Ta‐W‐Sn, Sn‐Fe and Sn around the cupola in space and a multi‐stage regularity in time. Finally a minerogenetic model and three key factors of tin minerogenesis are put forward for tin polymetallic deposits in the area.
