Fig. 3From: Simultaneous measurements of elastic wave velocities and electrical conductivity in a brine-saturated granitic rock under confining pressures and their implication for interpretation of geophysical observations a Compressional and b shear wave velocities in a dry rock sample AJG02. Velocities are shown as a function of confining pressure. Z-direction is parallel to the axis of the cylindrical sample. X- and Y-directions are perpendicular to Z-direction and mutually orthogonal. The letter for a compressional wave represents the propagation direction. The first letter for a shear wave is the oscillation direction, and the second letter is the propagation directionBack to article page
