Resumen:

A fault-fracture system that affects the Valley of Queretaro, Mexico, was investigated using a combined ground penetrating radar (GPR) and geotechnical technique. In order to delineate the geometry of fracturing, vertical GPR profiles were collected perpendicular to main pattern, with two different prospecting frequencies, 900 and 300 MHz. The analysis of the GPR profiles supported with the startigraphic record permitted to identify variations in deformation of layers that can be explained in terms of difference of thickness and compressibility. GPR profiles permitted to correlate vertical and lateral variations of the geological properties for a better understanding and forecasting of the distribution and behavior of fractures.
