GNGTS 2021 S essione 1.2 102 • Temperature distribution at 200, 500, 1000 meters depth; • Thermal conductivity map at 200, 500, 1000 meters depth (lithology-dependent); • Heat flow map at 1000 meters depth. Investigation of the thermal regime has enabled us to improves our knowledge of the ge- othermal potential of the Hyblean domain occurring at shallow-intermediate depths and allowed the definition of low-enthalpy geothermal mapping at several depths scales useful for exploration and exploitation of low-enthalpy resources. Preliminary results on temperature gradient and heat flow maps provide new evidence of heat transfer properties of the south-eastern sector of Sicily as well the boundary conditions for more local and higher resolution thermal studies to investigate afterward.
