[EN] Geological and geophysical data acquired in several projects aimed to characterization of structures in granitic rocks, make possible
to evaluate the efficiency and resolution of several geological and geophysical methodologies for their study. The analysis of
the spatial distribution of fracture density in granitic bodies makes possible to identify fault damage zones as well as the central
fault cores. Measures of Fracture Index in a granitic massif can be used to generate 3-D stochastic models and simulations, which
provide an image of the architecture of fault zones and the related distribution of physical properties. Geostatistical methods are a
tool to integrate geological and geophysical data in 3-D. Borehole and surface geophysical data provide additional constraints for
fracture mapping of a granitic body. High resolution reflection seismic experiments together with azimut variable vertical seismic
profiles acquired in borehole, as well as surface tomographic 3-D acquisition, have proved to be very efficient in resolving the fault
structure of granites. |

[ES] El desarrollo de varios proyectos para la caracterización de macizos graníticos nos ha permitido evaluar la capacidad de resolución
y eficacia de diversas metodologías de trabajo geológicas y geofísicas. La distribución espacial de la densidad de fracturación
en macizos graníticos permite identificar el núcleo de las zonas de falla y las áreas dañadas de su entorno. Medidas del índice de
fracturación procedentes de la superficie y de los sondeos, pueden ser usadas para generar modelos 3-D estocásticos que proporcionan
una imagen de la arquitectura de las zonas de falla y la distribución de propiedades físicas en el cuerpo granítico. Los métodos
geoestadísticos proporcionan la posibilidad de integrar los datos geológicos y geofísicos para visualizar la distribución de fracturas
en el macizo rocoso. Experimentos de sísmica de reflexión de alta resolución, junto con perfiles sísmicos verticales adquiridos en
sondeos con azimut variable y experimentos tomográficos 3-D adquiridos en superficie, han demostrado ser metodologías válidas
para resolver la estructura interior de los granitos. |

This work is in part a synthesis of the geological and
geophysical results of a multidisciplinary project carried
out for the environmental restoration of an old uranium
mine, supported by ENRESA. We are grateful to Julio
Astudillo, Carmen Bajos, Álvaro Castañón and Manuel
Lucini who made possible this research.ƒ |
