摘　　要：在福建德化国宝乡—赤水镇一带发现一处饮用天然矿泉水水源地,水源地SZK2偏硅酸含量为35.1 mg/L,SZK3锶含量为0.64 mg/L,水质分别达偏硅酸型、锶型饮用天然矿泉水标准,群井抽水试验显示其日涌水量超过230 t。矿泉水主要储存于南园组第四段火山岩地层中,受近南北向及北西向断裂构造控制,地下水在断裂构造循环过程中,通过溶解周围的矿物质,使水中偏硅酸、锶含量达到饮用天然矿泉水标准。矿泉水的形成主要受岩石分布及其可溶性、水岩相互作用、围岩裂隙发育程度、水源涵养及补给条件等因素影响。通过总结研究区矿泉水成因,对今后寻找该类型矿泉水具有一定的指导意义。A natural mineral water source for drinking has been discovered in the area of Guobao Township—Chishui Town,Dehua County,Fujian.The SZK2 water source has a silicic acid content of 35.1mg/L and the SZK3 water source has a strontium content of 0.64mg/L.The water quality meets the standards of silicic acid type and strontium type natural mineral water for drinking.The group well pumping test shows that its daily water inflow reaches more than 230 t.Mineral water is mainly stored in the fourth volcanic rock formation of the Nanyuan Formation,controlled by nearly north-south and northwest trending fault structures.During the circulation of the fault structures,groundwater dissolves surrounding minerals,making the content of silicic acid and strontium in the water reach the standard for drinking natural mineral water.The formation of mineral water is mainly controlled by factors such as rock distribution and solubility,the degree of water rock interaction,the development of rock structure fractures,water conservation and supply conditions.By summarizing the origin of mineral water in the study area,it has certain guiding significance for searching for this type of mineral water in the future.
