Abstract

Thermal waters at Ciarinem and Cilayu, Pameungpeuk, West Java, Indonesia have different characteristics: Ciarinem water is a steam heated sulfate type and occurs as hot springs, whereas Cilayu water discharges as hot pools and is a chloride water type. Their chemical compositions indicate that the thermal waters are outflows of a volcanic–magmatic associated geothermal system. The solute geothermometers calculate that the subsurface reservoir temperatures range from 150o to 200ºC.
