摘 要 贵州省石阡县溪沟锶-偏硅酸型饮用天然矿泉水形成于石阡枢纽背斜南端,石阡枢纽断裂西盘沟谷的断裂破碎带上,含水层为奥陶系下统桐梓—红花园组(O1t-h)地层,岩性为灰岩及白云岩,存储类型为“带状存储”兼“层状存储”的较复杂类型,主要补给来源为大气降水。经测算,矿泉水可开采量为420.53 m3/d,水中锶含量达1.35 mg/L,偏硅酸含量25.24 mg/L,均满足饮用天然矿泉水界限指标要求,可命名为锶-偏硅酸型饮用天然矿泉水。该矿泉水具有纯天然、无污染、水质优、口感好等特征,有较高的开发利用价值。

Abstract: The strontium-silicic acid type drinking natural mineral water in Shiqianxigou, Guizhou province is formed in the southern tip of the carpathian hub and the fracture zone of the west disc of the Shiqian hub, the aquifer is the formation of tongzi - red garden formation in Ordovician, lithology is limestone and dolomite, storage type is the more complex type of "strip storage" and "layered storage",the main supply sources are atmospheric precipitation.The recoverable amount mineral water is 420.53m?/d, the Strontium in water contents 1.35 mg/L, metasilicate contents 25.24mg/L, all meet the requirements of drinking natural mineral water limits,can be named strontium - metasilicate for drinking natural mineral water; The mineral water has high development and utilization value of the characteristics of pure natural, pollution-free, water quality, good taste and so on.

Keywords: Shiqianxigou; Strontium-silicate mineral water; Forming conditions; Water quality characteristics

1 概况

随着经济社会的发展和人民生活水平的不断提高,饮用水的安全与健康越来越受广大人民群众关注,矿泉水以其天然无污染、安全、卫生、富含有利于人体健康的矿物质而逐渐成为热门商品[1]。贵州省石阡县溪沟锶-偏硅酸型饮用天然矿泉水位于贵州省石阡县城所在地汤山镇城北鲜花村溪沟,距县城约3.3 km,有乡村公路相互连接,交通十分方便。2009年11月,石阡县被中国矿业联合会命名为“中国矿泉水之乡”,2012年6月被中国老年学会授予“中国长寿之乡”,优异的自然地理条件造就了溪沟锶-偏硅酸型饮用天然矿泉水,其具有纯天然、无污染、水质优、口感好等特征,同时富含锶、偏硅酸等有利于人体健康的矿物质,深受当地人民群众喜爱,市场前景广阔,具有较高的开发利用价值。……
