Abstract

When magnesiowustites (Mg (sub 0.5) Fe (sub 0.5) )O and (Mg (sub 0.8) Fe (sub 0.2) )O were heated to > 1000 K at P > 80 GPa, to simulate conditions relevant to the Earth's lower mantle, an XRD study showed that they may dissociate into Mg-rich and Fe-rich oxide components. Such decomposition into lighter and heavier phases will cause dynamic effects that could lead to mantle heterogeneity.
