Mineral chemistry was conducted on a reddish mineral extracted from Nigerian peralkaline granite. The major element contents such as high TiO2 (8 - 9 wt.%) and FeO (40-41 wt.%), low SiO2 (40-42 wt.%), Na2O (6 wt.%), and CaO (0 wt.%) are similar to aenigmatite reported elsewhere. However, I could not classify and confirm the mineral using excel spreadsheet.
