摘要
对宁夏盐池地区的地下水和土壤、岩石中的含氟量进行了系统调查。结果表明:盐池地区处于强烈的干旱积盐环境中,水土环境呈碱性反应。第三系泥岩和侏罗系泥砂岩地层的含氟量远高于其它地层,为本地区高氟地下水的主要形成因素之一。风积沙、厚层第四系冲洪积层和白垩系砂岩地层为本地区的主要低氟水赋存地层,是今后找水的目标含水层。
The fluoride content of groundwater, soil and rock in Yanchi area, Ningxia Hui Autonomous Region was investigated. Yanchi located in a severe arid and salt-accumulating area, the soil, rock and groundwater are all alkaline. The fluoride content in tertiary mudstone and Jurassic sandstone and shale is much higher than that in other layer, this is one of the main reasons of the formation of high - fluoride groundwater. Wind deposited sand, deep quarternary allu -fluvial layer, and cretaceous sandstone is the main low- fluoride aquifer, and is the main object for groundwater prospect.
