Several springs are located in this thermal field: Acqua Santa, Macerina, Casuccini and Sillene well. They are located close to the contact between the lower complex of the «Tuscan series» (Triassic limestones and dolomites) and Pliocene formations (sands and clayey sands, clays and silty clays). According to the groundwater flow scheme, the former formations represent the geothermal reservoir and, where they outcrop, the recharge areas. Thermalized fluids rise through direct faults, having an apennine orientation. In order to locate a new production well, electrical tomography and TDEM prospection were performed. Geophysical interpretation led to the construction of 1D imaged and 2D sections showing the main tectonic features. The different electrical behaviour of the hydrogeological units disclosed a fault located near the old Sillene well; this tectonic feature caused the uplifting of Triassic formations towards the north-east. A new production well was located close to the fault in the uplifted sector with excellent results as it captured the thermal aquifer at a depth of 30 m with a discharge up to 70 l/s.201 440 - PublicationOpen AccessMetodi geofisici integrati per l'individuazione della tomba del Papa Alessandro IV (Viterbo).Vengono illustrati i risultati di uno studio geofisico integrato condotto nella cattedrale di San Lorenzo a Viterbo,a cui è stato unita all’analisi storica ed archeologica partita dal 2010, nell’ambito del progetto di ricerca della sepoltura di Papa Alessandro IV, ancora oggi l’unica fra le tombe dei pontefici della storia a trovarsi in un luogo sconosciuto.

; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ; ;The comparison between so many studies groups will cause a quite long temperai development, but fmally it will allow to obtain a twofold goal: first to bring to light Pope Alexander IV tomb and then, more importantly from thè scientifìc point of view, put compared, in a single site, 9 geophysical different methods, non-invasive and non-destructive and 15 different instruments, therefore the data will be very important in various fields, historical, archaeological, geological and architecrural. The techniques compared in thè "research project of Pope Alexander IV tomb" will be: Ground Penetrating Radar (GPR), IDEM - Method in Time Domain Electromagnetic (EM61 - Metal Detector High Resolution), EM31 (FDEM) Electromagnetic Method in thè frequency domain, Electrical Tomography (ERT), Microgravimetric Method, Sonic Tests, Survey Seismic Tomography, Magnetometric Methods.The first results are beginning to emerge and by analyzing the methodologies separately and comparing the results obtained with the different techniques.122 12
