    In order to progress in our understanding of processes occurring in igneous systems on Earth and other terrestrial planets, it is important that we have the capability of simulating experimentally the conditions of formation for these rocks. Such experimental simulation presents a particular challenge, as it involves the simultaneous application of pressure and temperature in chemically complex and highly reactive systems. In our laboratories we focus on investigations of the Earth's interior - we mainly work on processes in the Earth's upper part of mantle and crust.

    Experimental facilities located in our laboratory include apparatus designed to take natural and synthetic compositions to pressures and temperatures that are found in the Earth's crust and upper mantle. These facilities include end-loaded piston-cylinder apparatus (up to 4 GPa, 1800°C), a 1000t multi-anvil apparatus (up to 20 GPa, 2000°C), large volume box furnaces, and three vertical one atmosphere gas-mixing furnaces (1600°C). Further equipment in the high-pressure laboratories include several hydrothermal cold seal apparatus (0.4 GPa, 800°C) and numerous externally heated low-temperature autoclaves (200°C, <0.1 GPa). Associated auxiliary equipment includes welding apparatus, balances, polishing and cutting facilities, and several drying furnaces.
