| 摘 要： | 石门县上五通石膏矿床是我省发现的大型优质石膏矿床之一。矿区水文地质条件比较简单,石膏矿体具有良好的隔水顶、底板,保存完整。但由于构造活动及地表风化作用的影响,矿层在地下水的作用下,其保存情况及矿石类型形成了明显的分带性。笔者以矿区水文地质条件为基础,将石膏矿的溶蚀带划分为淋滤带、溶滤水化带和水化带;并对矿区水文地质条件的成矿作用和地下水对早期形成的硬石膏矿床的改造和破坏作用进行了具体分析;提出了寻找隐伏石膏矿的水化学标志。这对研究石膏矿床的成因、指导找矿,以及加强矿山建设都是有益的。

| Abstract: | Shangwutong gypsum deposit in Shimen county is one of the largest high quality gypsum deposits discovered in our province. The hydrogeological condition of the mine is simple. The. gypsum orebodies are provided with good waterinsulating reef and floor and are preserved well. But due to the influence of the structural activities and weathering in the surface, under the action of underground water, the ore types and the preservation of ore seam showed obvious zoning. Based on the hydrogeological conditions of the mine, the author divided the dissolved zone of the gypsum deposit into leaching zone, leaching-hydrating zone and hydrating zone. And the metallogenesis of hydrogeologic condition in the mine and the reformation and destruction of underground water on the previously-formed anhydrate deposit are concretely analysed. The hydrochemical criteria for finding concealed gypsum deposits are proposed out. The above studies are useful for investigating the origin of gypsum deposits, guiding the exploration and enhancing the construction of the mine. |
