摘要
浙江省饮用天然矿泉水资源丰富,类型多样。本文收集全省范围内79处矿泉勘查报告的数据,按照含水介质和水化学特征,分类总结矿泉水的特征和规律。结果表明,围岩矿物为矿泉水的形成提供物源基础,偏硅酸是省内矿泉水最容易达标的组分,主要来自铝硅酸盐矿物的水解。省内矿泉水主要受断裂构造控制,呈带状分布的特征明显。花岗岩类裂隙和变质岩裂隙具备形成大中型矿泉水的天然优势,风化裂隙能提供额外的赋存空间和隔水保护。矿泉水补给来源主要为现代大气降水,少数水源地有沉积盆地封存水和断裂深循环水混合补给。根据典型矿泉水离子组分和氢氧同位素分析,循环补给年龄普遍在10~50年之间,更新速度快,经济价值稳定。研究成果对浙江省矿泉水开发保护、促进地方经济发展具有积极意义。
The resources of natural mineral water are abundant,and the types are diversity in Zhejiang Province.This study summarizes the characteristics and laws of mineral water according to the characteristics of water-bearing medium and water chemistry basing on the data of 79 mineral spring exploration reports in the whole province.The result shows that the surrounding rock minerals provide the provenance basis for the formation of mineral water.The most easily attainable component of mineral water in Zhejiang Province is metasilicic acid,mainly from hydrolysis of aluminosilicate minerals.The characteristic of the mineral water is obviously zonal distribution and mainly controlled by the fault structure,Granite-like fissures and metamorphic rock fissures having the natural advantage of forming large and medium-sized mineral water,weathered fissures providing additional storage space and waterproof protection.Most supply of the mineral water from Zhejiang Province is modern atmospheric precipitation and a little from mixed supply of sequestered water in sedimentary basins and deep circulation water in faults.Circulating supply has the age of 10-50 years generally,fast renewal speed,and stable economic value according to the analysis of ionic components and hydrogen and oxygen isotopes of typical mineral water.The research results have positive significance for the development and protection of mineral water in Zhejiang Province and the promotion of local economic development.
