Dipole-Dipole Study of the Travale Geothermal Field

Summary

The present paper deals with the application of the dipole sounding method in the Travale geothermal area (Tuscany) and is a part of a wider research addressed to a systematic study of the exploring power of the method. It constitutes a first attempt for the realization of an efficacious prospecting technique in areas of geothermal interest. For this reason the choice of the known geothermal area of Travale appears largely justified owing to the numerous informations at present available about geological, hydrogeological, geophysical and geothermal aspects. We give at first a brief outline of the adopted field technique and of the method used for data acquisition. Then, after showing the obtained field dipole apparent resistivity diagrams, the method of transformation into Schlumberger equivalent curves is discussed together with its implications as far as quantitative interpretation is concerned. Two preliminary geological sections are finally presented as a result of a combined geoelectrical, geological and geothermal interpretation.
