Techniques for measuring the elastic wave velocities of melts and partial molten systems under high pressure conditions

Abstract

The Earth's deep interior is only accessible by indirect methods, first and foremost seismological studies. The interpretation of these seismic data and the corresponding numerical modelling requires measurements of the elastic properties of representative Earth materials under experimental simulated in situ conditions. Different techniques and results for experiments under crustal and mantle conditions are described.

“…Research carried out at a later date confirmed the unique commercial possibilities on a world scale for this pressure chamber. During the 13 years of operation of the high performance gas pressure chamber in the ZIPE, there was not a single accident [37][38][39][40][41][42][43][44][45][46][47][48][49][50][51][52]. In the early 1980s, a new building for department V was also urgently required.…”
