【 摘 要 】

The formation of several sources of hot springs in the Andes from Ecuador is the result of an intense volcanic activity due to the subduction of the Nazca oceanic plate under the South American continental plate. The aim of this study was to describe the hydrogeochemistry water geothermal origin, its chemical classification and relationship with the complex geology of Ecuador, using different hydro chemical diagrams (Stiff, Piper and Schoeller-Berkaloff). Geothermal waters can be divided into two groups. The first group, associated with an extinct volcanic activity produced in the Cenozoic, represents the Na+-Cl- type. The second group is associated with a young Quaternary volcanic activity and its types of water are Mg2+-HCO3-, Na+-HCO3-, Na+-SO42-, Mg2+-SO42-.
