The dielectric properties of low porosity polycrystalline marble and granite rocks were investigated using broadband dielectric relaxation spectroscopy (10-2-106Hz) at fixed room temperature (295K). The water content of the specimens was varied between 0 and 0.22% (mass of absorbed water per mass of dry rock material %). The dielectric relaxation spectra were found to exhibit large low-frequency dispersion that depends strongly on the water content. A thorough study of this dispersion reveals that the main part of the enhanced ε* values originates from bulk effects.
