Fig. 2: TEM images and electron diffraction of the recovered crystalline bridgmanite.
From: Pressure stabilizes ferrous iron in bridgmanite under hydrous deep lower mantle conditions
A, B Run#390-93, showing a nearly pure bridgmanite phase with grain boundaries recovered from 105 GPa and 2250 K; (C) and (D) Run#188-96, recovered from 108 GPa and 2250 K; (E) and (F) Run#332-82, coexistence of bridgmanite and Fe metal recovered from 92 GPa and 1850 K. The SAED data confirmed crystallinity of bridgmanite in all the runs. The black dots in (A) are marks for damages induced by electron irradiation during the EELS measurement.
