Generalized stratigraphic column (not to scale) of the Swiss Molasse Basin and the adjacent Folded Jura, showing aquifer properties relevant to the geological storage of CO₂. Aquifers are blue, aquitards orange. The rightmost column shows the eight main aquifer/seal pairs described in “Parameterization of the geological evaluation criteria” of the text. Stratigraphy based on Jordan (2007). Aquifer properties from Schegg et al. (1997) and from unpublished borehole data (SEAG, Swissgas)
