The Yinchanggou-Qiluogou Pb-Zn deposit is confined to the dolomite of the Upper Sinian Dengying Formation. Most of orebodies are controlled by faults and occur as lens, vein network and veinlet. Siliceous bandings and jasper which are closely related to the mineralization are hydrothermal filler. Geological setting and mineralization features indicate that the deposit belongs to MVT Pb-Zn deposit.
