摘要
The thermal-mineral waters in Siping'an district are hydrogeologically and geochemically unique in Shanxi.their occurrence is controlled by faulted structures in Precambrian rocks.The physico-chemical properties, hydrochemical thpes ,major and minor elements ,dissolved gases and organic suboances have been characterized to describe the hydrochemical features and therapeutic effect of the thermal-mineral waters. Hydrogen, oxygen, sulfur and helium isotope compositions of the waters were measured tO explain their ages, origlm and related geochemical procee. The thermal-mineral waters have been formed as a result of the deep circulation of meteoric water in fractures and fissures of hard rocks. Miking of the thermal waters from the deep with cold groundwaters in the Quaternary sediments and the Hutuo River water takes place when the thermal waters move upward to the discharge area.
