Multi-Anvil Press

A Rotating Multi-Anvil Press constructed by Max Voggenreiter GmbH is installed in the high-pressure hall of the GFZ. The apparatus consists of an 800 tons hydraulic press and a Walker-type multi-anvil module. The whole apparatus is rotatable by 360° perpendicular to the press axis. Schmidt and Ulmer (2004) demonstrated that by rotation it is possible to overcome common fluid/solid or melt/solid separation during high-pressure experiments. The press covers the pressure range 3.0-23.0 GPa, corresponding to earth's depths of circa 100-650 km, thus allowing the study of geomaterial properties and geochemical processes at mantle conditions.

Cross-section through a Pt capsule containing the run product of a static experiment (left) performed at 12 GPa and 1200°C. The different colours symbolize the different minerals: ringwoodite (blue), wadsleyite (green) and olivine (red). On the right: reaction product under the same experimental conditions but rotated with 4° sec showing now the equilibrium texture: ringwoodite (green), wadsleyite (yellow) and olivine (red).
