Summary:This report concerns a detailed field study of the factors which affect groundwater flow patterns and the distribution of fluid compositions within some representative Jurassic mudrocks. Fluid movement within clay-rich rocks (mudrocks) in sedimentary basins is extremely slow, and knowledge of the nature of processes occurring within these low-flow environments is limited. Novel methods of measuring in situ pressure heads in the clay-rich lithologies, and of sampling pore-fluids and in situ groundwater samples within a vertical mudrock profile, have been developed and tested. —Modified journal abstract.
