Nonhydrostatic stress, an often‐ignored source of seismic anisotropy, is universally present in the subsurface and may be as common as intrinsic or fracture‐induced anisotropy. Nonhydrostatic stress, applied to an initially transversely isotropic

Fracture toughness (K [Ic] ) is a measure of the ease with which a fracture can propagate through a rock. The ability to predict fracture toughness from thin sections would allow: a) evaluation of those petrographic characteristics most affecting a r

In many geological situations, there is a need to monitor fluid migration and associated phenomena. Acoustic emissions (AE) that result from fluid pressure diffusion from a borehole can potentially provide useful information about migration paths, lo

During forced water infiltration into a dry granite rock in the dilatant state, migration of a water front and a clear positive feedback between acoustic activity and water flow into microcracks were revealed by means of AE hypocenter locations and v

Cores from two natural joints were studied to estimate the degree of correlation between the surfaces and the distribution of apertures. Matched pairs of profiles were taken from both surfaces of each joint. These profiles were then placed together t

In the past decade the number of studies about microcracks in rocks has rapidly increased. This review of recent work concentrates on microcracks in rock as separate entities, emphasizing microcrack morphogenesis, kinematics, dynamics, population sta

Permeability was measured during creep deformation of a tight sandstone and a granite at upper crustal conditions. With water at 100°C as the pore fluid, permeability first decreased then increased during loading to peak stress. Thereafter, permeabi
