Fig. 17From: Influence of depth, temperature, and structure of a crustal heat source on the geothermal reservoirs of Tuscany: numerical modelling and sensitivity studyPart of cross-section A–A′ showing temperature isolines (in \(^{\circ } \mathrm{C}\)) for the reference case (continuous line) and Variation 3 (dashed line). The different rock units are shown in varying colours/shades. The location of Borehole I is shown with a thick, continuous line. Arrows within the deep reservoir depict convection cells. The bottom boundary marks the position of the K horizon in the reference case. It is shallower in Variation 3Back to article page
