The southern part of the Da Hinggan Mountains is the only tin‐polymetallic concentration area in northern China. Based on ore‐forming element assemblages, three metallogenic series, the Sn(W), paragenetic Sn–polymetallic, and poly‐metallic series, are recognized. The Sn(W) series, consisting of greisen, skarn and vein types, is associated with ilmenite–series, potassic feldspar (Kf)–granites. The polymetallic Pb–Zn–Cu series with porphyry, skarn and vein types, is related to magnetite–series, granodiorite – monzonite. On the contrary, the paragenetic Sn‐polymetallic series mineralization is associated with the coexisting igneous activities of Kf‐granite and granodiorite–monzonite, and it is suggested that the paragenetic Sn‐polymetallic series is caused by the superimposed mineralization with tin from ilmenite‐series magma and polymetallic elements from magnetite‐series magma–hydrothermal system. All the three series possess similar metallogenic age, concentrating on J 3 –K 1 (130–150 Ma). The melting of high maturity and tin‐rich Xilinhot Proterozoic complex (micro–massif) during Mesozoic period, could generate the ilmenite–series, tin‐bearing felsic magma, and cause the tin mineralization in the southern part of the Da Hinggan Mountains.
