摘要: 吉林荒沟山铅锌矿床赋存于中元古界老岭群珍珠门组白云石大理岩中,层控特征明显.通过对矿床地质、成矿元素Zn/Pb比值、方铅矿和闪锌矿中的微量元素、硫和铅同位素组成特征、矿物包裹体成分特征、矿源层特征等的讨论,认为本矿床为一沉积改造型层控矿床.沉积作用是本矿床成矿物质来源的基础,改造作用是形成本矿床的主要因素.珍珠门组是提供成矿物质来源的重要矿源层.

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.
