Fig. 2

Lithostratigraphic sequence in the Upper Rhine Graben with the potential geothermal reservoir units (modified after GeORG Projektteam (2013) and Deutsche Stratigraphische Kommission (2016)). It is indicated whether the fluid flow in the reservoir horizon is dominated by fractures (F) or matrix (M). For a detailed visualization of the Tertiary succession, see also Fig. 9. The regional importance of each horizon is indicated by the color gradient
