研究了永城矿区高氟地下水中氟的来源及其地质构造控制因素 .认为地层中含氟矿物的溶解是深层地下水中氟的天然来源 ,而土壤中含氟矿物及土粒表面呈吸附态的氟是该区浅层地下水中氟的主要物质来源 .该区独特的地质构造为含氟水进入提供了通道 ,并构成其富集单元
The source of fluorine in fluorite groundwater in Yongcheng mining area and the controlling factors of its geological structure are studied.The dissolution of fluorine-bearing minerals in the formation is the natural source of fluorine in deep groundwater, while the surface of fluorine-bearing minerals and soil particles in the soil are in adsorption state Fluorine is the main source of fluorine in the shallow groundwater in the area, and the unique geological formation in this area provides access to the fluoridated water and constitutes its enrichment unit
