Pore space characteristics of samples H13-17 (A–D) and H22-8 (E–G) determined by µCT analysis. Moldic pores (up to large mesopores) dominate the packstone. Scale: 0.5 mm. Plug diameter 13 mm (A). Vertical section shows considerable porosity. The dashed line marks the position of C (B). Horizontal section (C). Reconstructed pore space. Colors mark parts of the pore system that are each connected by throats > 26 µm (D). The plug comprises delithified siliceous marlstone (lower part) and delithified calcareous mudstone (upper part). Scale: 0.5 mm. Plug diameter 13 mm (E). Vertical section shows thin fractures (micropores). The dashed line marks the position of G (F). Horizontal section showing fine fractures and rare micro- to small mesopores. The matrix exhibits no pores connected by throats > 26 µm (G)
