摘要
岗子矿泉水位于承德市丰宁满族自治县鱼儿山镇岗子村西南,其水化学类型为重碳酸-钙(HCO3-Ca^2+)型,水中偏硅酸含量30.89~35.82 mg/L,变化较大,为偏硅酸型饮用天然矿泉水。通过多期的水质检测结果对比,认为其水质较为稳定。结合研究区的地质、水文地质特征,分析认为该矿泉水补给来源主要是头道河河谷的中上游地区的大气降水,通过岩石裂隙、断裂构造,进入到地层深部,在深部运移流通过程中,与周围岩石发生了一系列水岩反应形成矿泉水,并最终以人工钻孔的形式被揭露。
Gangzi mineral water is located in the southwest of gangzi village,yueshan town,fengningmanchu autonomous county,chengde city,its hydrochemical type is bicarbonate-calcium( HCO3^--Ca^2+) type.The content of metasilicic acid in the water is 30.89 ~ 35.82 mg/L,which changes greatly.It is a natural mineral water of metasilicic acid type.The water quality was considered to be stable by comparing the results of multi-phase water quality tests.Combined with the geological and hydrogeological characteristics of study area,the analysis shows that the main source of the mineral water supply is the atmospheric precipitation in the middle and upper reaches of the Toudaohe River Valley.Through the rock fracture and fracture structure,the mineral water enters into the deep stratum.In the process of deep migration and circulation,a series of water rock reactions with the surrounding rocks have taken place to form the mineral water,which is finally exposed in the form of artificial drilling.
