Buffering in the Assemblage Staurolite-aluminum Silicate-Biotite-Garnet-Chlorite

Basic Information
Author: Day, H. W. and Giaramita, M. J.
Description:The assemblage muscovite-quartz-staurolite-aluminium silicate-biotite-garnet-chlorite with H2O (SABGC assemblage) is invariant in the K2O-FeO-MgO-Al2O3-SiO2-H2O (KFMASH) system. Such five-phase AFM assemblages should be absent in nature, but reported occurrences from at least ten localities suggest that either the assemblage internally controls H2O or non-KFMASH components stabilize one or more of the phases.
