Abstrakt: | The aluminous calcium-ferrite type phase (CF) and new aluminous phase (NAL) are thought to hold the excess alumina produced by the decomposition of garnet in MORB compositions in the lower mantle. The respective stabilities of CF and NAL in the nepheline-spinel binary (NaAlSiO Supplementary Information: The online version contains supplementary material available at 10.1007/s00410-024-02129-w.
