Fig. 16From: Influence of depth, temperature, and structure of a crustal heat source on the geothermal reservoirs of Tuscany: numerical modelling and sensitivity studyDifferences between borehole temperatures in the reference scenario and the variations at potential borehole locations (I–IV, i.e. i–iv, respectively). Temperature variations (Var. 1 and 2) are in red, depth variations (Var. 3 and 4) in blue, and the dotted line represents the shape variations (Var. 5). The various units, i.e. Pliocene (a), Ligurian (b), TUaB (c), Burano (d), Farma (e), and the deep reservoir, are separated by dashed horizontal lines Back to article page
