Pressures and temperatures equivalent to that at the base of the upper mantle and top of the lower mantle can be achieved with multi-anvil devices. Hall (1958) described a tetrahedral multianvil device used to generate pressures high enough to synthesize diamond. Further developments led to the octahedral multi-anvil device (Kawai and Endo, 1970), refined by many Japanese scientists (e.g., Akaogi and Akimoto,1977 Onodera, 1987 Ohtani, 1987). Walker et al.
