黄河源九龙滩饮用天然矿泉水成因分析

Genesis Analysis of Drinking Natural Mineral Water in Jiulongtan of the Yellow River Source Region

黄河源九龙滩地区多处泉水锶含量达到国家现行饮用天然矿泉水水质标准。通过调查区域水文地质条件、分析泉水水化学和动态特征等,发现该地区矿泉水形成的主要原因为基岩山区接受大气降水的补给后沿构造裂隙汇集后运移,进入深循环,在遇到压扭性构造阻水后,在断裂带上盘上涌,以上升泉的形式泄出地表,完成地下水的深循环过程。

The content of strontium in many springs in Jiulongtan area of the Yellow River source reaches the current national drinking natural mineral water quality standard.Through the investigation of regional hydrogeological conditions,the analysis of spring water chemistry and dynamic characteristics,it is found that the main reasons for the formation of mineral water in this area are as follows:after receiving the recharge of atmospheric precipitation,the bedrock mountain area migrates along the structural fissures and enters the deep circulation.After encountering the water resistance of the pressure-torsional structure,it rises on the hanging wall of the fault zone and discharges the surface in the form of rising springs to complete the deep circulation process of groundwater.
