   Range of pressures and temperatures now accessible with static compression techniques in the laboratory. (Left) Graphical representation of accessible pressures and temperatures, specifically, those attainable with diamond anvil cell methods, which are used to generate the most extreme conditions. The fields include so-called resistive-heating and laser-heating methods, as described in articles in this issue. Estimated variations in pressure and temperature with depth in various planets are indicated. (Right) Cutaway of the earth's interior, showing the pressures at the various boundaries within the planet (i.e., upper and lower mantle, core–mantle boundary, and inner–outer core).
