| Abstract | El Hoyo-Monte Galan is a geothermal prospect area in the Central Western Nicaragua. The current state of the project is feasibility stage with drilling exploration carried out in 2009. Hydrothermal activity in the surrounding area has been depicted by the hydrothermal alteration found in well N1 which comprises mineral phases such as quartz, chlorite, wairakite, alunite, epidote, and other high temperature minerals. Fluid inclusion microthermometry analysis was conducted on the well cuttings collected from the geothermal well N1 with homogenization temperature ranging from 178°C to 322°C, suggesting a good agreement with the hydrothermal mineralogy. |
