Abstract: The Huanggoushan Pb-Zn deposit,occurring in the dolomite marble of Mesoproterozoic Zhenzhumen formation,is obviously controlled by strata.Study on the geology,the Zn/Pb ratio of ore-forming elements,the microelements in galena and sphalerite,the S and Pb isotopic compositions,the inclusions of minerals and the source bed shows that it is a stratabound deposit of sedimentation reformation type.Sedimentation is the basis for the source of ore-forming material;while reformation is the essential factor for the forming of the deposit. The Zhenzhumen formation is the source bed for ore-forming material.
