Hydrogeochemical Study of Ciseeng Thermal Springs, West Java Province, Indonesia


[Trisakti University, Indonesia]

Indonesia is a country that has considerable geothermal potential either associated with volcanism or non-volcanism. Due to complexity of geological feature in Java Island there is a geothermal manifestation that located in Ciseeng Area, Bogor Regency, West Java Province, Indonesia. Regionally, the geological condition of Ciseeng is composed of Bojongmanik Formation, Young Volcanic Formation and Alluvial Formation and locally composed of Limestone Unit, Andesite Fragment Breccia Unit, Alluvial Deposit and Travertine unit. There are three geothermal manifestations that spread over in three locations, namely Gunung Panjang, Gunung Peyek and Gunung Kapur. All of the manifestations consist of warm spring, warm pools and Travertine hills. Ciseeng geothermal area is classified as volcanogenic low relief type with several geochemical characteristics such as having a chloride water type, based on the geochemical plotting has one reservoir source, fluid condition in partial equilibrium. The estimation of reservoir temperature by using cation geothermometers is in the range of 153°C-184°C. According to isotope analysis from four samples that spreaded in three geothermal manifestations located in mixing zone.
