“SEM micrograph (BSE mode) showing thin chamosite platelets (bright grey) embedded in a kaolinite-grup mineral (dark grey). On the left side there is some relic pyrrhotite (bright grey). The homogeneous grey phase is calcite. Polished section of a pyrrhotite-rich ore specimen from the well-known "erythrite locality".
