Keywords:Effective diffusion coefficient, Formation factor, Through-diffusion method, Porosity measurement, Resistivity measurement

Matrix diffusion is one of the important for evaluating solute transport in crystalline rock. In this study, effective diffusion coefficient, porosity, and resistivity of crystalline rock were measured.There was a positive correlation between the formation factor calculated from the resistivity measurement and the effective diffusion coefficient calculated from the transmission diffusion test. Therefore, the effective diffusion coefficient can be estimated from the resistivity measurement of crystalline rock.
