Description
To investigate the pressure/temperature regime of the Earth´s crust and shallow parts of the upper mantle, at the GFZ three piston cylinder presses are installed and run. Two of the three presses are non-endloaded piston cylinder apparatus ("Johannes-type"), with which pressures up to 2.1 GPa and temperatures up to 1400 °C can be reached. Salt/graphite- or natural fluorite/graphite-assemblages (latter for temperatures larger 800 °C) are of 2.2 cm diameter. Pressures were calibrated according the equilibrium albite = jadeite + α-quartz. For experiments in the pressure range of 2.0-5.0 GPa an endloaded piston-cylinder press ("Boyd & England-type") is used for temperatures up to 1650 °C.
