P–T conditions for the back-transformation in bridgmanite. Bridgmanite (Brg, black circles) becomes amorphous (partially, blue diamonds; completely, blue circles), followed by orthoenstatite crystallization (OEn, red squares) with increasing temperatures at ~ 1–4 GPa, and directly back-transforms to high-P clinoenstatite (HP CEn) at ~ 8 GPa. A double-headed arrow indicates the temperature condition for partially amorphization observed in Durben and Wolf (1992)
