Abstract
Based on and sulphur isotopic composition, two types of steam Rehai geothermal field are identified. One higher Concentration, the of is in the range to (vs CDT), from which the than 250?C. The other is with lower and concentration, the of is in the range to fiom which the and are 180?C-21 in good agreement with quartz temperature. The thermal water in the Rehai field is of local meteoric origin. Maximum shift is less than (vs SMOW). Mixing is widespread and could be identified on isotope and solute chemistry.
