“…This was confirmed through the variation of geothermal flux, identified in the region compared to the average geothermal gradient. In fact, the distribution of the geothermal flux in terms of "heat-flow density" (HFD) at the level of the Mediterranean basin and, in particular, at the southern segment of the Geotraverse (EGT-S) campaign, shows a heat flux anomaly superior than 100 MW/m 2 in the Jeffara region (Bouaziz et al, 2015;Gabtni., 2006;Mraidi et al;Fig. 12 (C)).…”
