英文摘要 | Geothermal waters in the Xi'an area, Shaanxi Province were studied using hydrogeochemistry and isotopic properties to determine groundwater age and identify the recharge source. The delta(18) O and delta D values of geothermal waters sampled from the Qinling mountain front fall on the meteoric water lines. Waters at increasing depth and distance from the Qinling foreland, exhibit enriched delta(18)O but fairly constant delta D. Most of shallow geothermal groundwater samples fall on the meteoric water line, which suggests that shallow ( < 1500m) geothermal waters are separated from deep ( > 1500m) geothermal waters. C-14 ages of geothermal water range from 6,000 to 30,000 years, indicating long residence time. Flow velocity was calculated using C-14 ages along the flow lines. Results show that geothermal water flows at 1. 7 m/year from south to north, and 2. 5 m/year from west to east in the tertiary formations in Van area. The delta(18)O and delta D values of karstic groundwaters in the North Mountains plot on the meteoric water line but at the more enriched end than the geothermal waters, indicating that they have different sources of recharge. Flow velocity calculated for the karstic groundwaters is 25 m/year from west to east and 5 m/year from north to south. |
