granitic rocks can be established on the basis of the spatial
variability of geological, geophysical and geochemical
parameters. In the North Fault of the Mina Ratones area
(SW Iberian Massif, Spain), fault rocks along two studied
traverses (SR-2 and SR-3 boreholes) exhibit systematic
changes in mineralogy, geochemistry, fabrics and microstructures
that are related to brittle deformation and
alteration of granite to form cataclasite and subsequent
gouge. The spatial distribution and intensity of these
changes suggest a North Fault morphology that is
consistent with the fault-core/damage-zone model proposed
by Chester et al. (1993) to describe a fault zone
architecture. North Fault damage zone thickness can be
defined by the development of mechanically related
mesoscopic faults and joints, that produce a Fracture
