Abstract
Consolidated carbonate rocks have relative low porosities but high specific surface areas thus showing a fine dispersion of the pore volume. The pore radii distribution derived from Hg-capillary pressure curves show maxima which are in good accordance with the grain size distribution. This and the rather large portion of not communicating porosity which is deduced from the difference between total porosity and pore volumes measured by Hg-capillary pressure and benzole-vapor adsorption leads to the conclusion that the porosity of the investigated carbonate rocks is the rest of the primary intergranular porosity of the sediment before compaction.
The petrographic consequences of pore geometry on material transport and reaction velocities are discussed.
