Summary Ultrasonic compressional wave velocities obtained by the pulse transmission method in a few pyroxenites, dunites, peridotites, eclogites and serpentinites subjected to hydrostatic pressures of the order of 5 kb are reported. Results obtained show a rapid increase in velocity ranging from 2 to 30 per cent due to a compression of 1.5 kb and little increase beyond this pressure. The results of the changes in wave velocity are discussed in the light of porosity and petrography of the samples.
