Sixteen unpublished analyses of Broken Hill manganese silicates (two pyrox‐mangite, one rhodonite, four hedenbergite, and nine bustamite) from the papers of the late Dr W. T. Schaller are presented. They have been complemented with additional analyses by the electron microprobe to define the compositional fields of these minerals. Data are provided on the relationship of these minerals with tephroite and garnet. The occurrence of roepperite (zincian tephroite) at Broken Hill is discredited, and its validity is doubtful. Dannemorite from Broken Hill has a composition close to Mn2(Fe,Mg)5Si8O22(OH)2, and can be considered a valid amphibole subspecies.
