摘要
本文基于热水及相关天然水的氢氧同位素(D和^(18)O)数据论证了漳州盆地地下热水为大气降水深循环成因,并属于中低温系统,用同位素方法讨论了海水与地热水混合关系及混合比。
Geothermal water in the Zhangzhou Basin is of high salinity. This paper focuses on the analysis and interpretation of oxygen and hydrogen isotope (2H, 18O) data for geothermal and other relevant natural waters from the basin. Based on the relationship between geothermal water and meteoric water the origin and genetic type of geothermal water are discussed. Studies on the isotopic composition of geothermal water provide evidence for the origin of salinity-high geothermal water, i.e., the mechanism of seawater involvement. The authors believe that geothermal water in the Zhangzhou Basin belongs to low-to medium-temperature thermal water formed from deep circulation of meteoric water and that the involvement of seawater in geothermal water has strong influence on the isotope composition and chemistry of the latter.
