摘　　要：铜山岭矿田是湘南多金属矿田之一,庵堂岭铅锌矿床位于铜山岭矿田的北部。矿床的地质地球化学特征反映出成矿元素与岩体关系密切,成矿元素的地球化学行为具有明显的分带性,同时在运移和沉淀的过程中受构造制约。通过对硫、铅同位素特征分析,矿区的成矿物质来源于岩浆热液并具深源性;矿床成因为与深源中酸性岩浆有关的中温热液矿床。Tongshanling orefield is one of polymetallic ore deposits in the south of Hunan. Antangling Pb - Zn deposit is located in the north of Tongshanling orefield. Results of ore deposit geochemistry and geochemical anomaly show that mineralizing elements with obvious zonation in space are related intimately with intrusive bodies, and controlled by structure during migration and precipitation. Sulfur and lead isotope analyses suggested that ore - forming materials came from deep source magmatic fluids. Genesis of the deposit belongs to medium temperature hydrethermal fluid type related with deep-origin intermediate to acidic magma.
