摘要
Significant economic sediment-hosted base metal deposits occur in Lanping, Changdu, Yushu and Tuotuohe areas of Sanjiang region in southwest China. The authors hold that they were formed during Indian-Asian continental collision and developed within the fold-thrust belt combined with thrust and/or strike-slip-related Cenozoic basins in the interior of the collsional zone. The authors tend to classify the Jinding, the Zhaofayong, the Dongmozhazhua, the Mohailaheng, and the Chaqupacha Pb-Zn deposits and the Pb-Zn(-Cu-Ag) deposits in eastern Baiyangping ore belt as MVT-like deposits, and to classify Pb-Zn(-Cu-Ag) veins in western Baiyangping ore belt and the Cu veins as polymetallic veins.
