We thank Jiuhua Chen, Michael Vaughan and Donald Weidner for the continued development and operation of the SAM-85 apparatus at the NSLS; and Ian Jackson and Akira Yoneda for their helpful and constructive reviews. This paper was written while the corresponding author (RCL) was a visiting scientist in the CNRS laboratory of Jannick Ingrin and Olivier Jaoul at the Université Paul Sabatier in Toulouse, France; he thanks them for their hospitality and support. This study was supported by the National Science Foundation under grant EAR 99-80491 to RCL. Mineral Physics Institute Publication No. 312. The in situ ultrasonic and X-ray experiments were carried out at the X-17B1 beamline of the National Synchrotron Light Source (NSLS),which is supported by the US Department of Energy, Division of Materials Sciences and Division of Chemical Sciences under Contract No. DE-AC02-76CH00016.

N2 - Sound velocities in polycrystalline San Carlos olivine have been measured to pressures of 7 GPa at room temperature in a 1000 t uniaxial, split-cylinder apparatus (USCA-1000) of the Kawai multi-anvil type. These velocities and elastic moduli are in good agreement with those calculated from single-crystal moduli determined by previous investigators. In preliminary experiments in a DIA-type, cubic anvil apparatus (SAM-85), ultrasonic interferometric techniques were used in conjunction with synchrotron X-radiation to determine the elastic properties of San Carlos olivine under simultaneous high pressures and temperatures. We demonstrate the feasibility of such experiments even in specimens which have undergone plastic deformation at elevated pressures and temperatures.
