Description:
This study evaluated the geothermal potential of Caldara di Manziana in central Italy. The chemical com-position of gas emissions was used for geothermometric-geobarometric estimations and the total amountof CO2released was assessed. The subsurface geology was reconstructed using data from deep exploratoryand shallow temperature-gradient wells. The bottom of the superficial volcanic deposits, the thickness ofthe impervious flysch cover and the top of the geothermal reservoir hosted in fractured Mesozoic lime-stones were reconstructed by a 3D-GIS modelling. Our results are consistent with a geothermal reservoir(T ∼140◦C) at ∼1000 m depth, with an estimated thermal energy capacity of 46–48 MWt.
