Based on a mechanistical understanding of solute migration in pure clay at nanometric scale, a model has been developed to evaluate the effective diffusion coefficient De in clay-rocks at the centimetre scale from the description of the mineralogy (and its heterogeneity) of the rock at the micrometer scale.
