Fig. 4From: Hydrogen partitioning between stishovite and hydrous phase δ: implications for water cycle and distribution in the lower mantleH+ contents of stishovite as a function of Al3+ content. ST, starting stishovite pre-synthesized; AA, stishovite coexisting with hydrous phase δ after annealing. Some of stishovites in previous studies coexist with liquid phase or hydrous phase egg.
