Description
Summary:The research location is administratively included into the sub-district of Citeureup, Bogor, West Java. Geographically, it's located at coordinates BT 106°54'36"-107°00'00" 6°35'46"-6°40'74" LS. This study aims to determine the temperature of the reservoir of subsurface, the determination of fluid type and the origin of hot water on the surface manifestation and the process of formation under the surface. The method used is descriptive method and chemical analysis including geothermometer and geoindicators based on geothermal fluid geothermal chemistry data. Water chemistry analysis based on geoindicators showed that type of hot water of study area was dominated by sulfate water with relatively high proportion of sulfate (SO4) to concentration of Cl and HCO3 as the outflow area identifier in condition of relative Na-K-Mg proportion and relative K-Na and Mg-Ca concentration diagram at the position is not equal (immature water) and the area is outflow geothermal system. Mg is very dominating with concentration. The high concentration of Mg in calculations and plotting results on immature water indicates that in the formation of surface water geothermal manifestation comes from reservoirs that have been mixed with meteoric water and reaction / interaction with the rocks it passes. Temperature of subsurface manifestations based on geothermometers Na-K-Ca in the study area of approximately 50.617 to 92.6279°C which is belong to low temperature geothermal system.
