| 1 | Lusakite occurrence, Rufunsa District, Lusaka Province, Zambia | scattered very small violet to violet-brown pleochroic grains in high-grade "ferrolite" (staurolite-kyanite-quartz-magnetite gneiss), with abundant blue Co-bearing staurolite, kyanite, quartz and magnetite. Additional oxides (hematite+ilmenite; minor rutile) and minor sulfides (linnaeite, cobaltpentlandite) are present, as is sparse sillimanite and retrograde(?) margarite and clinochore. |

Click on any node to view relationships. Formula-derived relationship network for the group members above. Use Find related species to add formula-neighbour species outside the current group view. Solid links show inferred chemical differences; dashed violet links show same-formula crystallographic differences. Hydration states are not treated as relationship changes. These relationships do not imply any real-world substitution reactions between these species.
