| Abstract | Heat flow and geothermal gradient exploration have been carried out in a 30 km long zone along the southwestern flank of the Cordillera de Guanacaste (a chain of andesitic strato volcanoes) in Costa Rica as part of an integrated program of geothermal exploration. Several attractive targets have been drilled and an extensive geothermal system on the slope of the volcano Miravalles associated with the fumeroles of Las Hornillas has been outlined. Additional drilling has been done at the areas of Borinquen and Las Pailas where fumeroles also occur. Extensive flow of groundwater off the flanks of the volcanoes has complicated the gradient exploration technique, but not severely. The geothermal. systems outlined are probably typical of other systems geologic settings. |
