We investigate the high-pressure phase diagram of the hydrous mineral brucite, Mg(OH)<sub>2</sub>, using structure search algorithms and ab initio simulations. We predict a high-pressure phase stable at pressure and temperature conditions found in cold subducting slabs in Earth's mantle transition zone and lower mantle. This prediction implies that brucite can play a much more important role in water transport and storage in Earth's interior than hitherto thought. The predicted high-pressure pha ...[more]
