Abstract
Recent geochemical has confirmed that spring 'discharge water is near neutral with chloride contents less than 375 ppm. Maximum temperatures estimated from geothermometry and mixing models are 220-230 C. evidence of lake water intrusion and only a small oxygen shift due to high temperature interaction with rocks. The chemical compositions indicate that the highest chloride water rises in the south, and bicarbonate waters from the north mix in the central part of the field .
