Abstract:

Based on hydrogen and oxygen isotope study, the origin, recharge as well as the temperature, circula- tion depth and mixing proportion of geothermal waters in Guanzhong area were analyzed. Results showed the geo- thermal water is the mixture of net thermal water and normal ground water. According to the calculated tempera- ture of SiO2geothermometer, the temperature and depths of geothermal reservoir for net geothermal water in the study area are estimated at about 80℃ ～ 121℃ and 1 146.84～ 1 779.38 m respectively. The hydrogen and oxy- gen isotope tracers and tritium dating show that the sources of geothermal water have certain relation with present day meteoric water. However, it is derived from meteoric water in the higher mountains area in the southern part of the area rather than from meteoric water in the local area.
