Shock-induced temperatures of CaMgSi2O6Results are presented from experiments on CaMgSi2O6 (diopside) single crystal, an end-member pyroxene relevant to studies of the composition of the earth's mantle. Also, experiments were conducted on diopside glass with a density 86 percent that of the diopside crystal. The shock-induced radiation from diopside is used to constrain the temperature of its shock-compressed (Hugoniot) states. The results are combined with other data to place constraints on the high-pressure phase relations in the CaMgSi2O6 system. These constraints are compared with existing models for the earth's mantle. The results imply that the temperature of the D-double prime region must be less than 3000 K.
