Bauxite
Bauxite is a sedimentary rock with a relatively high aluminium content. It is the world's main source of aluminium and gallium. Bauxite consists mostly of the aluminium minerals gibbsite (Al(OH)3), boehmite (Y-AlO(OH)) and diaspore (α-AlO(OH)), mixed with the two iron oxides goethite (FeO(OH)) and haematite (Fe2O3), the aluminium clay mineral kaolinite (Al2Si2O5(OH)4) and small amounts of anatase (TiO2) and ilmenite (FeTiO3 or FeO.TiO2).

Anyolite
Anyolite is a metamorphic rock composed of intergrown green zoisite (Ca2Al3(SiO4)(Si2O7)O(OH) ), black/dark green pargasite (NaCa2(Mg4Al)(Si6Al2)O22(OH)2 ) and ruby (Al2O3:Cr).
Unakite
Unakite is a pink and green metamorphic rock composed of pink orthoclase, green epidote, and colorless to milky quartz.
