SEM micrograph (BSE 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) forming the matrix of anhedral sphalerite grains (bright). The matrix consists of slightly zoned dolomite (darker grey) and anhedral quartz (dark). This material was described in: Rieck, B., Kolitsch, U., Voudouris, P., Giester, G., and Tzeferis, P. (2018) Weitere Neufunde aus Lavrion, Griechenland. Mineralien-Welt, 29(5), 32-77 (in German).

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). This material was described in: Rieck, B., Kolitsch, U., Voudouris, P., Giester, G., and Tzeferis, P.
