“SEM micrograph (SE 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 bit 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".
