Title: Compressional Wave Velocities in Basic Rocks 
Author: Christensen, Nikolas I.
Date: 1968-01
Publisher: University of Hawai'i Press
Citation: Christensen NI. 1968. Compressional wave velocities in basic rocks. Pac Sci 22(1): 41-44.
Abstract: Compressional wave velocities determined by measurement of travel
times of pulses at pressures to 10 kilobars are given for specimens of basalt. Variations
of velocity with propagation direction are related to feldspar orientation and
inhomogeneity in alteration of the specimens. Velocity differences reported for
diabase, gabbro, eclogite, and basalt can be explained in terms of variation of
density and mean atomic weight . The basalts have the lowest compressional wave
velocities of basic rocks. The low velocities are a consequence of slight alteration,
high mean atomic weight, and relatively low density.
