【摘要】:氟是人体的必须元素之一,饮水中氟元素过量会导致地氟病。高氟地下水的形成机制一直是水文地球化学研究的一个热门话题。利用在张掖盆地开展1∶5万水文地质调查所获得的大量水位、水质资料,运用水化学和氘氧同位素方法,在较高精度水平上探讨了龙首山前高氟地下水的形成机制。研究结果表明,龙首山前地下水中的F-主要来源于龙首山含氟岩石,通过季节性洪水的方式补给到盆地的第四系含水层中,并与盆地上游来源的低氟地下水发生混合,使龙首山前地下水分为三个条带。
[Abstract]:Fluorine is one of the essential elements in human body. Excessive fluoride in drinking water can lead to endemic fluorosis. The formation mechanism of high fluorine groundwater has been a hot topic in hydrogeochemistry research. Based on the data of water level and water quality obtained from the 1: 50 000 hydrogeological survey in Zhangye Basin, the formation mechanism of high fluorine groundwater in the Longshoushan Mountains was discussed on the basis of hydrochemistry and deuterium oxygen isotope method. The results show that the F- in the groundwater in front of Longshou Mountain is mainly derived from fluorine-bearing rocks in the Longshoushan Mountains. It is recharged to the Quaternary aquifer of the basin by seasonal flood and mixed with the low-fluorine groundwater from the upper reaches of the basin. The groundwater in front of Longshou Mountain is divided into three bands.
