A preliminary magnetotelluric (MT) survey was survey was carrid out in Southern Tuscany,Italy, to delineate the resistivity structure in an area wich does not not belong to classic geothermal zones but is still characterized by anomalousy haigh heat flow. the one-dimensional (1-D) resistivity inversion shows a low resistivity zone characterized by high heat flow. based on 1-D resistivity information, detaled tow-dimensional (2-D) resistivity modellling was caried out. A reasonable 2-D resistivity model was proposed for shallow depth, and was found to be in good agreement with tha available geological and geophysical information on the area. the present results show a low resistivity anomaly, charaectized by high heat flow. the anomaly seems to exstend beyound tha classic Mt.Amiata geothermal region
