“SEM micrograph (SE mode) of a polished section of the fuchsite-rich carbonate-schist matrix of the small white pustule-like annabergite aggregates on the roof of a large underground hall (see https://www.mindat.org/photo-244091.html).
Fuchsite as micaceous aggregates (grey, with some charging effects; very low hardness) forming the matrix of anhedral sphalerite grains (grey). The matrix consists of slightly zoned dolomite (darker grey) and anhedral quartz (dark).
