Geochemical studies of geothermal manifestations in the Northern Zone of Mt. Seulawah Agam , one of which is Ie Jue manifestation, has been conducted. In this study, water geochemical analysis of cations and anions content was performed to observe the surface characteristics of manifestations, the type of water manifestation, the water balance of reservoir depth and to estimate depth temperature using geothermometer equations. Cations and anions measurements were conducted using atomic absorption spectroscopy, UV-Vis spectrophotometer and acid-base titration. The data analysis was determined using spreadsheet version 3 Powell Geoscience Ltd.3 September 2012 by Powell & Cumming. The geothermal water Ie Jue manifestation was acidic pH, water sulphate type was obtained from the geoindicator Cl-SO 4 -HCO 3 and the immature water was based on plot Na-K-Mg ternary diagram. Its reservoir temperatures ranged from 690 °C to 761 °C in accordance with Na/K geothermometer equations based on results of Na/K Giggenbach and Fournier. The Ie Jue manifestations indicated a high-temperature geothermal system (high enthalpy) that could be characterized when the average temperature reached higher than 225 °C and suitable for power plant development.
