Resumen

The groundwater flow in zones of low permeability, as granites, is mainly associated with zones of fracture.
For this reason the characterization of the fractures is fundamental, both in surface as in depth, and must
integrate geological information (geological mapping, structural analysis), geophysics (mainly electrical
and electromagnetic methods) and geochemistry (radon and others gases) with hydrogeology. In this work we analyze the geophysical response of a strike-slip fault zone by means of three 2D resistivity models. The objective is to investigate the presence of several conductive zones and their geometry in depth. The obtained results allow to control the geometry in depth of the fractures, the gaps between the different mapped traces along the fault zone as well as the thickness of landfill. All this information will be useful for the hidromechanical simulation of the massif, and to check the geometry and gas permeability calculated from emanometry.
