Mn-rich mineral paragenesis containing Mn-winchite, Mn-aegirine-augite, and Mn-rich garnet (calderitic spessartine) is found in hematite-rich siliceous schists from the Sanbagawa metamorphic belt in the Kanto Mountains. Chemical composition of amphibole widely changes with compositional layers in a siliceous schist; Mn-winchite in aegirine-augite+garnet+hematite+quartz layer, actinolite in hematite+calcite+quartz layer, and Mn-cummingtonite in hematite+quartz layer.
