Short summary
Clay is the prominent barrier material in the geosphere, but diffusion of dissolved species is possible. Diffusion parameters are commonly determined on small samples, disregarding heterogeneity. With positron emission tomography (PET), we monitored heterogeneous transport patterns on larger samples. From the time dependence of the spatial tracer distribution, we derived reliable anisotropic diffusion coefficients, and found indications of preferential transport zones.
