Description

EPM single point analyses of all coexisting phases (bridgmanite, clinoenstatite, davemaoite, ferropericlase, forsterite, garnet, quenched liquid, ringwoodite, tuite and wadsleyite) in a phosphorus enriched peridotite at upper to lower mantle transition zone conditions. Experiments were performed in a P-T range of 15-25 GPa and between 1600 and 1800°C. Additional SIMS analyses of the phosphorus content in bridgmanite, high pressure clinoenstatite and ferropericlase.
