Galaxite also known as ‘mangan-spinel’ is an isometric mineral belonging to the spinel group of oxides with the ideal chemical formula Mn2+Al2O4.Galaxite is the manganese (Mn) rich endmember of the aluminium (Al) series of the spinel group. Divalent iron (Fe) and magnesium (Mg) readily substitute for the manganese in the crystal structure. Trivalent iron may also substitute for the aluminium.
