Fig. 11

Vertical cross-section along A–A′ (see Fig. 9 for its position) showing specific surface heat flow (top) and temperature (bottom). The shaded areas represent reservoir layers of high permeability. In the shallow reservoir, conduction is superposed by topography-driven lateral advection, whereas convection is the dominant heat transport mechanism in the deep reservoir
