Diffusion in the Matrix of Granitic Rock. Field Test in the Stripa Mine


A migration experiment with the objective to investigate the existence of a connected pore system in undisturbed rock has been performed in the Stripa mine at the 360 m-level.

Since all three tracers (Cr-EDTA, I and Uranine) that were used in the experiment migrated at least 11 cm into the rock under a three month period, this experiment indicates the existence of a connected pore system in “undisturbed” rock.
