Abstract
Gunung Ciremai has a parasite cone of Gunung Kromong. In this area, there are several surface geothermal manifestations having different physical and chemical characteristics, i.e. as hot springs, hot pool and kaipohan.
Results on water chemistry and stable isotope of 18O and D indicate that the origin of thermal fluid in the research area is meteoric water. The water has been heated by volcano-magmatic activity of Gunung Ciremai. Within reservoir, the thermal fluid then boils at temperature of no more than 210°C. Hot water then flow laterally through the surface as chloride water appearing at Gunung Kromong and flank of Ciremai, whereas steam fraction continuously discharges and condensates into groundwater and surface water at high elevation. Consequently, sulfate and bicarbonate water are formed.
