青海省河南县某饮用天然矿泉水勘查评价

Exploration and evaluation of natural mineral water for drinking in Henan County of Qinghai Province

矿泉水含有人体所需的众多矿物质、微量元素以及气体成分,具有纯净无污染的特点。青海省河南县研究区矿泉水中锶含量0.523~1.74 mg/L,矿化度0.75~0.78 mg/L,Ca^(2+)、HCO_3^-毫克当量均大于75%,属于重碳酸钙含锶天然饮用矿泉水。通过对研究区内矿泉水出露情况、补径排条件、矿泉水赋存条件、形成机制以及水化学特征进行评价。结果表明:富锶的地球化学特征、断裂构造及地形地貌条件是矿泉水形成的主要因素,且各项指标均符合国家标准的要求,矿泉水中锶的含量0.523~1.74 mg/L,属优质的富锶矿泉水,可作为饮用天然矿泉水开发利用。

Mineral water contains a large number of minerals,trace elements and gas components required by the human body,which has the characteristics of pure and pollution-free. The content of Strontium in mineral water of Henan County in Qinghai province is 0. 523 - 1. 74 mg/L,salinity 0. 75 - 0. 78 mg/l,Ca2＋ and HCO3-mg equivalent are all greater than 75 %,which belong to calcium bicarbonate and strontium natural drinking mineral water. Through the evaluation of mineral water exposure,drainage and drainage conditions,mineral water storage conditions,formation mechanism and hydrochemical characteristics in the study area. The results show that the SR rich geochemical characteristics,tectonic and topographic conditions are the main factors of mineral water,and the indicators are in line with the requirements of the national standard,the content of Strontium in mineral water by 0. 523 - 1. 74 mg/L,is rich in strontium mineral water quality,as the development and utilization of natural mineral water for drinking.
