| Abstract: | Hejiaping lead-zinc deposit is hosted in the Sinian system of Denying Formation in the upper dolomite,obviously limited by the horizon.The phenomenon of significant ore body wear layer is controlled by joints,cracks and other small structure.Natural types of ore contain pyrite galena sphalerite-type,sphalerite crystallites galena(pyrite) type,sphalerite type and galena type.Type of wall-rock alteration are mainly barite,dolomitization,pyritization,silicification and carbonation.Type of ore genesis is carbonate deposition of the central plains to the mineral deposits in water seepage. |
