Description

High-Pressure Research: Applications in Geophysics contains the papers presented during a U.S.-Japan joint seminar held in Honolulu, Hawaii, 6-9 July 1976. The seminar brought together scientists engaged in high pressure-high temperature research to exchange ideas on the latest state-of-the-art developments, their experimental results, and their latest interpretations with regard to the significance of these results to the geophysical sciences in general. Four formal sessions were held. Of the forty-two papers presented at the seminar, thirty-nine appear as contributed papers and three as abstracts in this volume. The papers in Session I examine the geophysics and geochemistry of the crust and upper mantle. The contributions in Session II focus on phase transitions related to Earth's deep interior. Session III is devoted equations of state and shock wave experiments while Session IV covers instrumentation, pressure calibration, and standardization.
