中文摘要:泗顶矿田的铅锌硫化物矿床以碳酸盐岩为主岩，成矿与岩浆活动和变质作用无关。目前一般认为属于沉积改造型层控矿床。然而许多宏观和微观地质事实都说明该矿田的铝锌硫化物矿化是两个不同性质的地下水含水系统的含矿地下水沿印支期断裂破碎带排泄混台成矿的产物。作者认为属于地下水再造矿床。以该矿田的成矿物质来源、成矿作用方式、地层、构造、水文地质、地球化学等综合控矿因素和矿化就位机制为重点，建立了其地下水成矿模式。

A groundwater metallogenic model for the Siding lead-zinc orefield
Abstract:The Jead-zinc suKide deposits in the Siding orefield are hosted by Devonian carbonate rocks, and their ore-forming process had nothing to do with magmatic activities and metamorphism. At present, it is generally held that they are stratabound deposits of sedfmentary transformation type.Nevertheless, lots of macroscopic and microscopic geological phenomena all indicate that the lead-zinc sulfide deposits in this orefield were formed by mixed mineralization of ore-bearing groundwater in two different ground-water-conraining systems along tile Indo-Sininan fractural belt. The author considers that the key factors for their formation are 1)two groundwater containing systems with different natures. 2) abundant ore-forming materials in these systems, 3)mixing and transporting channels of ore-bearing groundwater in these systems and 4)the water table as the oxidation-reduction boundary of groundwater in the process of mineralization. On the basis of these considerations, the author has established a generalized model for thiS type of ore deposits.
