After an overview of the most recent results of static high-pressure and high-temperature experiments, we present a review of the mineralogy of shocked meteorites. The high-pressure minerals in these rocks result either from solid-state reactions or from the crystallization of melts at high pressures. Comparisons of naturally shocked samples with samples processed in dynamic experiments must be made with extreme caution. The durations of the equilibrium shock pressure experienced by meteorites can vary over at least three orders of magnitude (10−2 s to 10 s), and they lie within the lower range of the duration of static experiments conducted...
