This paper detects the main features of the conductivity structures in the exploited geothermal field of Travale in Italy, where a detailed study was conducted using Magnetotelluric (MT) data in 2004. In this area, the long period natural-field MT method proved very useful for subsurface mapping purpose so that deep resistivity structures were determined properly. Using 1D inversion schemes, MT data were processed and modeled. To have the best possible interpretation all modes of data were examined.
The resistivity model obtained from MT data is consistent with the geological model of the Travale region down to five kilometers. Analysis of the new MT data-set suggests signatures of a deep geothermal reservoir in the area. The conductive zones which are recognized in the resistive basement in many sites can clearly be interpreted as the flow of the fluids in the faults and fractures of the metamorphic rocks.
