SEM micrograph (BSE mode) showing three bright grains: from bottom to top they are: Fe-rich violarite, chalcopyrite and zircon. On the left a pseudmorph of TiO2 (probably rutile) and calcite after titanite. The matrix is quartz. Polished section of a pyrrhotite-rich ore specimen from the well-known "erythrite locality". 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).

SEM micrograph (BSE mode) showing both fresh titanite (small grey, rounded grains, bit NE of centre and in lower left) and several pseudomorphs of fine-grained TiO2 (probably rutile) (grey) and calcite (medium-grey) after titanite. The three bright grains in the lower left are, from bottom to top (see also linked micrograph), Fe-rich violarite, chalcopyrite and zircon. The matrix is quartz. Polished section of a pyrrhotite-rich ore specimen from the well-known "erythrite locality". This material was described in: Rieck, B., Kolitsch, U., Voudouris, P., Giester, G., and Tzeferis, P.
