| Study on the Relationship between Quaternary High-fluorine Groundwater and Geothermal Water in Xiaotangshan Area, Beijing |
| The fluorine content of deep groundwater generally exceeds the standard in Xiaotangshan area of Beijing, which seriously restricts the regional water supply. Based on the collection of basic geological, hydrogeological, and geothermal geological data, the relationship between quaternary high-fluorine groundwater and geothermal water was studied. The study showed that Xiaotangshan area is in the nuclear part of the anticline. In this area, the geothermal reservoir is in contact with the quaternary strata. Under the influence of tectonic stress, a large number of tensile fractures have developed in the geothermal reservoir. Moreover, as quaternary strata are loose and thin, this area has become a geothermal enrichment zone. Under high temperature and pressure, the fluoride content of geothermal water is generally high. Because of the mixing of geothermal water and quaternary deep groundwater, the fluoride content of quaternary deep groundwater increases and high-fluoride groundwater is formed. |
