The post-stishovite phase transition in hydrous alumina-bearing SiO^sub 2^ in the lower mantle of the earth

Silica is the most abundant oxide component in the Earth mantle by weight, and stishovite, the rutile-structured (.../mnm) high-pressure phase with silica in six coordination by oxygen, is one of the main constituents of the basaltic layer of subducting slabs. It may also be present as a free phase...
