Abstract

Ultrasonic measurement of P and S velocities of Apollo 11 lunar samples 10020, 10057 and 10065 to 5 kbar pressure at room temperature shows a pronounced increase of velocity (as much as twofold) for the first 2 kbar. The travel times predicted from the velocity-depth curve of sample 10057 are consistent with the results of the Apollo 12 seismic experiments. At pressures below 200 bar, the samples are highly attenuating; for both P and S waves, the value of Q is about 10.

We are also grateful to William Brace and David Wones for making valuable suggestions during the course of the experiment. We benefited from discussions with Frank Press, Nafi Toksoz and Ralph Wiggins concerning various seismological problems related to this experiment. Dr. Gary Latham kindly made available to us, in advance of publication, some of the results obtained by the Apollo 12 seismic experiments. Financial support was provided by the National Aeronautics and Space Administration contract NAS9-8102.
