From: High nitrogen solubility in stishovite (SiO2) under lower mantle conditions
(Left) Back scattered electron (BSE) image of recovered sample from 28 GPa and 1,400 °C (OT2259). (Right) BSE images of two samples in OT2259: (a) Al-free system and (b) Al-bearing system. Circles indicate analyzed points. St denotes stishovite, Brg bridgmanite Brg2 and Brg4 in the Al-bearing sample contained iron. Dotted circles indicate analysis points located in cracks or intergranular, which are not discussed in this paper. This figure was created by Ko Fukuyama using Microsoft Power Point and Excel (OFFICE 2016).
