    Abstract

    The high resistivity and stiffness of granitic rocks make them to be excellent media for the propagation of electromagnetic and seismic waves. Permeable fractures reflect and attenuate the wave energy. Both surface and down-hole probes have been used at several sites. The examples present the technical advances from the shallow high-resolution seismics with large ranges of investigation to the very precise ground penetration radar techniques. Some of the mapped fractures are characterized by hydrogeological pumping tests and geophysical borehole logging.
