| Abstract |
A first approaching towards the characterization of the geothermal potential at the Galeras Volcano (Colombia), starting with the tentative definition of the dynamic qualities, and the interactions between the basic constituents associated to the existence of it´s geothermal systems. For this purpose, a joint analysis and interpretation of information provided by previous geological, geochemical and geophysical studies is developed with a geothermal criterion, defining features such as: the extension and location of the heat source, , the possible fluid discharge and recharge zones, and their circulation pattern, the lithological units that can constitute a geothermal reservoir and/or a seal layer, the presumed origin of the hydrothermal manifestations and their relation with the source of heat. Highlighting: 1.The existence of a transitory magmatic chamber, with cortical contribution and moderate differentiation and a primary magmatic chamber of basic composition at estimated depth greater than 13 Km. 2. The conditioning of the fluid circulation pattern by Buesaco Fault 3. The NW and SE sectors of the volcanic building as the regions of greatest interest for future studies of geothermal prospecting. |
