Hydrochemistry and formation of the Huailai hot spring in Hebei, China

摘要：

The Huailai hot spring occurs in the Sinian siliceous carbonate in the Huailai county in northwest Hebei province of China. The spring is of low TDS and Na. Ca-HCO3 type, and its temperature is 38 ℃. Chemical and isotopic analyses suggest that the hot water is meteoric in origin and undergoes a deep circulation to about 1900 m. The temperature of the geothermal reservoir is approximately 66-67 ℃. The residence time of the hot water is estimated to be about 40 years with the Ra-Rn method. It is a hot spring that is representative of low temperature. It occurs in sedimentary rocks and is not directly controlled by faults.
