Ferronigerite-2N1S is an iron, tin, alumino - hydroxide mineral that naturally occurs around sillimanite - quartz veins. Ferronigerite-2N1S belongs to the nigerite group, högbomite supergroup.

Mar 14, 2018 · Nigerite is the first mineral to be discovered in which both tin and aluminium are essential constituents. Its chief interest to mineralogists lies in its close relationship to minerals like spinel and corundum based on a close-packed …

Mar 14, 2018 · A new tin mineral, which has been given the name ‘nigerite’, was discovered in June 1944 during au investigation of the tin-bearing pegmatites of Kabba Province, central Nigeria.

mica rock carries 35 % nigerite, the remainder being tourmaline, sillimanite, chryso- beryl, and some opaques, half of which is columbotantalite. Accessories are zircon, andalusite, and cassiterite. The nigerite occurs associated with muscovite, in clusters of separate crystals.

Originally named nigerite, for the type locality in Nigeria. Renamed according to the new nigerite group nomenclature as Fe dominant mineral and the 2N1S polysome.

- Indicates mineral may be doubtful at this locality. - Good crystals or important locality for species. - World class for species or very significant. (TL) - Type Locality for a valid mineral species. (FRL) - First Recorded Locality for everything else (eg varieties). Struck out - Mineral was erroneously reported from this locality.
