Formula:
[(Fe2+,Mg,Zn,Al)3(Al,Ti,Fe3+)8O15(OH)]2
Colour:
Reddish brown to brownish black
Specific Gravity:
4.04 (Calculated)
Name:
Named for dominant iron and its relation to högbomite. The prefix ferro- reflects that it is a högbomite where the spinel module is dominated by the hercynite component (FeAl2O6). The root is for Arvid Gustaf Högbom (11 January 1857, Vännäs, Västerbotten, Sweden - 19 January 1940, Uppsala, Sweden), Professor of Mineralogy and Geology at Uppsala University. The suffix designates the polysome. The numbers refers to the total number of Nolanite (N) and Spinel (S) modules in the crystal structure.
A polysomatic Högbomite Group mineral composed of two nolanite modules (N) and two spinel modules (S) where the spinel modules have ideally hercynite composition.
