A Metastable Aluminosilica Compound for Aluminum and Water Transport to the Upper Mantle

It has been suggested that crystalline “phase egg,” AlSiO3OH, with a ratio Al/Si=1 could carry aluminum and water to the mantle but its natural occurrences are still speculative. An amorphous phase with a fixed and unique, deep metastable eutectic Al2Si2O7 composition was produced in laboratory expe...
