Article history: Received 11th Feb. 2020 Accepted 06th Mar. 2020 Available online 29th Apr. 2020 The paper introduces several new research results on the metallization of wolfram, tin polymetallic in Huoi Chun area based on the application of traditional geological methods combining with the research method of ore material composition and the statistical mathematics. The research results draw some conclusions: Ore minerals in Huoi Chun area are formed mainly by the way of material deposition, crystallized from hydrothermal solution, filling various fracture systems with different development directions. The main minerals in the region are wolfram, tin, copper, zinc and bismuth; the metallization of wolfram, tinpolymetallic is formed during the hydrothermal ore creation, including three stages corresponding to three mineral paragenesis assemblage; in particular, the mineral paragenesis assemblage of the abiogenesis wolframite bismuth is a new discovery of the authors. The Sn, Cu, Pb, Zn, As and Cd elements have a relatively close correlation with each other, which is a specific combination of elements for the II (two) mineralization phase and the W, Co and Bi elements is typical for the III (three) mineralization phase of the hydrothermal ore creation period. The metallization of wolfram, tin polymetallic is formed which might be related to the intrusive magma activity that occurred during the Mesozoic Cenozoic period (?).
