| Abstract: | Xiaokang Mn-Ag polymetal deposit is controlled by Xikou Formation of Lower Triassic System,cataclastic zone and contact zone of granitic porphyry.The oxidized Mn-Ag polymetal deposit is formed by leaching accumulation.Exposing to hydrothermal fluid overprinting and reworking and weathering and leaching of Mn-bearing strata leads to enrichment of the ore materials in interformational cataclastic zone where the ore occurs.Cu-Pb-Zn ore bodies are located in outer contact zone of intermediately acidic granite(partially layered skarn) and the ore occurs as dissemination and fracture-filling.Skarnization and hornflization are the main alterations.The deposit is characterized by vertical Mn(Fe)-Ag,Pb,Zn-Cu,Pb,Zn zonation. |
