Clay rich formations are investigated thoroughly as candidate host rocks for the deep geological storage of radioactive waste. In the Mont Terri Rock Laboratory (Switzerland) Opalinus Clay is investigated with the aim to analyse its hydrological, geochemical and rock mechanical properties. Detailed investigation of the pore morphology and pore space contributes to the understanding of the sealing capacity, coupled flow, and associated deformation in clay. The Opalinus Clay formation is a fine-grained sedimentary rock deposited 180 Ma ago in a shallow sea compacted to a low porosity of 9–25% (depending on the measuring method used) and low permeability. On the regional scale the lateral variability of facies and lithology is low. Opalinus Cl...
