Tin–polymetallic Mineralization in the Southern Part of the Da Hinggan Mountains, China

: 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,...
