In-situ energy dispersive X-ray diffraction measurements of enstatite have been studied by using diamond anvil cell (DAC) with synchrotron radiation and laser heating in the range of 0~23 GPa and 293~2 000 K. We have found that enstatite transform to wadsleyite phase at 15.3 GPa and 1 600 K. At temperatures up to 2 000 K and pressure up to 23 GPa we have observed mixed phase of ilmenite and perovskite structure. The experiment further demonstrates that the density and seismic-wave velocity jumps are attributed to the phase transition of olivine and enstatite minerals.
