Geothermal prospecting with the magneto-telluric method (M.T.-5-E.X.) in the Travale area (Tuscany, Italy)

The application of a new method, namely the M.T.-5-E.X. (Musé 1973), to geothermal prospecting in the region of Travale (Tuscany, Italy) is described here.The aim is to test the efficacy of this method in revealing, on the inside of the geothermal area, the most fractured zones and possibly to localize where the fluids rise from the deeper layers. A first discussion of results is given and a model is proposed which fits the recorded facts. Although a full interpretation of the results will only be possible when the research foreseen in this zone is at a more advanced stage, it is already evident that the method is destined to be widely applied in the future in geothermal research.
