Abstract :
We study the dielectric properties of polycrystalline sandstone with inherent humidity, by employing the thermal depolarization (thermally stimulated depolarization current, TSDC) spectroscopy. We employ the advantageous selectivity of the TSDC scheme to identify and characterize different hydrophilic sites in sandstone
