GNGTS 2018 S essione 3.1 581 2.5 and locate in a thinned/transitional crustal domain. Finally, the favourability map for the supercritical geothermal resources has been evaluated in the Southern Italy regions considering of thermal structure, depth of the brittle-ductile transition, geodynamic setting and isotopic signature of deep crustal magmatic processes. The data were organized in form of raster maps and the Matlab environment provided the tools for processing the selected parameters. Scoring from 1 (less favourable) up to 5 (most favourable) the elements of the four maps and weighting from 0 to 1 each thematic map by the Analytic Hierarchy Process, the favourability index was calculated using the Index Overlay method. Such results can be seen as a useful planning tool for any geothermal supercritical project, and related exploration to be carried out in the Southern Italy in the future. Acknowledgements. This work was carried out within the framework of the GEOTHERMAL ATLAS OF SOUTHERN ITALY Project, one of six Projects constituting the Program “CNR per il Mezzogiorno” of the Italian National Research Council, aimed at improving know how in the fields of advanced technology for energy efficiency, environmental protection, agro-food innovative methodologies for the Made in Italy and biotech medicine production.

The modulation in depth of the top of the carbonate units hosting the regional hydrothermal reservoir and the comparison between the simulated (black line) and measured (red circles) temperatures in selected deep boreholes are reported in Fig. 1B. The modulation in depth of the 400°C isotherm is shown in Fig. 1C.
