Summary:Sequence of sedimentary rocks from the Lower Chalk to the Oxford Clay. The preservation of aragonite in such rocks suggests that little groundwater movement has occurred through the bulk of these clays. This would imply that most groundwater movement is likely to occur along any fractures that may be present. Such fractures may interconnect with adjacent aquifer units along which most transport of radionuclides would occur. The presence of smectitic clay minerals would strongly influence their retention of radionuclides by sorption and ion-exchange reactions. Compaction, calcite cementation, calcite dissolution and the diagenesis of biogenic silica have influenced the porosity and permeability of the rocks and will affect groundwater chemistry, and the nature of interactions with transported radionuclides.—Modified journal abstract.
