Shock-wave Equations of State of Minerals

Shock-wave data play a unique role in the study of the interior of the Earth in that at pressures of 500 kbar to 3700 kbar, or at equivalent depths in the Earth of 1200 km and 6400 km (center), dynamic techniques provide the only means of studying mineral properties in the laboratory. The relation betwaen shock pressure (p), shock-induced density (Q), and internal energy (e), along a curve called the Hugoniot, is the form of an equation of state for solids or fluids which is usually obtained with shock-wave techniques
