皖南黄山地区矿泉水资源分布及成因

皖南黄山地区多处区域赋存有丰富的天然矿泉水资源，类型多为重碳酸钙型含偏硅酸矿泉水。该地区的矿泉水资源分布与岩浆岩体的分布密切相关，且主要与印支期（晚三叠世）岩浆活动形成的花岗闪长岩有关，在花岗闪长岩分布区普遍赋存含偏硅酸饮用天然矿泉水。研究区矿泉水受断裂构造控制，赋存于花岗闪长岩的构造裂隙、节理裂隙和风化网状裂隙中，系地下水在深循环过程中经较充分的水岩作用而形成。分析研究该地区矿泉水资源的分布和成因，对其开发利用具有一定的指导意义。

Distribution and causes of mineral water resources in Huangshan region of southern Anhui Province

There are abundant natural mineral water resources in many areas of Huangshan region in southern Anhui Province, most of which are heavy calcium carbonate mineral water containing metasilicate mineral water. The distribution of mineral water resources in this area is closely related to the distribution of magmatic rocks, mainly related to the granodiorite formed by the magmatic activities in the Indo-Chinese period (late Triassic). In the distribution area of granodiorite, drinking natural mineral water containing metasilicic acid generally occurs. The mineral water in the study area is controlled by faulted structure and occurs in tectonic fissures, joint fissures and weathered network fissures of granodiorite. It is formed by sufficient water-rock action of groundwater in the process of deep circulation. To analyze and study the distribution and causes of mineral water resources in this area has certain guiding significance for its development and utilization.
