The grains are assigned to be non-interacting and randomly oriented spheres or ellipsoids of revolution elongated along (i00), (ill) or (ii0). Also, aPl~oximate expressions are given for samples containing multidomain grains with very strongly pinned walls. Susceptibility charge perpendicular to the stress axis is also considered.

Permeability and capillarity 772051 EFFECT OF HIGH-PRESSURE DEFORMATION ON I~MEABILITY OF OTTAWA SAND Byerlee, J D; Zoback, M D Am Ass Petrol Gee& Bull, V60, Ng, Sept 1976, P1531-1542 Reports lab bests of the deformation and flnddflow properties of an Ottawa sand under hy~rostatic confining pressure, trlaxial e~pression, and trlaxial extension. During deformation, permeability and pore-volt,he charges were measured periodically. The hydrostaticcompression teats bear on burial or formation pure-pressure charges associated with fluid withdrawal or injection. The triaxial-deformation experiments relate to the stremgth and deformational behaviour of granular materials arzl the permeability ard pore-volume changes that accompaw deformation. Some comparisons are made with crushed Westerly granite.

~1-93 A hlgh-resolution study of shocked Coconino Sandstone from Meteor Crater, Arizona, was undertaken using transmission electron microscopy to investigate the textural relations of high-pressure phases produced by meterorite impact. A detailed description of the reaction of porous sandstone to the passage of shock waves of milliseconds duration is derived and shock Hugor.~ot data for single crystal quartz, water, and wet and dry rocks are reviewed in order to provide pressure estimates for each type of rock and to provide a basis for comparing naturally shocked samples with laboratory data.

The fo~,~Llation is exact in that no low-loss approximations are made. Consideration is given to nonparallel propagation and attenuation directions with corresponding velocity anisotropy.
