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. Thus, reflecting most natural samples, the formula may be better represented as (Mn,Fe2+,Mg)(Al,Fe3+)2O4. It is sometimes used as a gemstone.

  • La galaxita és un mineral de la classe dels òxids, que pertany al grup de l'espinel·la. Rep el seu nom de la localitat de Galax, a Carolina del Nord, molt a prop de la seva localitat tipus. (ca)
  • La galaxita es un mineral de la clase de los minerales óxidos, y dentro de esta pertenece al llamado grupo de la espinela. Su composición química viene expresada por Mn2+Al2O4. Fue descrito por primera vez en 1932 por su presencia en Bald Knob, condado de Alleghany, Carolina del Norte, cerca de la localidad de Galax, en el estado vecino de Virginia, topónimo que a su vez proviene de la planta Galax urceolata, que crece en la zona.​​ Un sinónimo poco usado para este mineral es manganoespinela.

  • Galaxit (auch Manganspinell) ist ein selten vorkommendes Mineral aus der Mineralklasse der „Oxide und Hydroxide“ mit der idealisierten chemischen Zusammensetzung Mn2+Al2O4 und damit chemisch gesehen ein Mangan-Aluminat. In der Natur findet sich Galaxit allerdings überwiegend mit geringen Anteilen von zweiwertigem Eisen und Magnesium, die das Mangan, sowie mit dreiwertigem Eisen, welches das Aluminium in der Formel teilweise ersetzen (Substitution). Daher wird die Formel in einigen Quellen auch mit (Mn2+,Fe2+,Mg)(Al,Fe3+)2O4 angegeben. (de)

  • La galaxite, également appelée 'mangano-spinelle' est un minéral isométrique appartenant aux oxydes du groupe du spinelle de formule chimique idéale MnIIAl2O4. La galaxite est le pôle riche en manganèse (Mn) de la série aluminium (Al) du groupe du spinelle. Le fer (Fe) divalent et le magnésium (Mg) se substituent facilement au manganèse dans la structure cristalline. Le fer trivalent peut aussi se substituer à l'aluminium. Par conséquent, reflétant la composition de la plupart des échantillons naturels, sa formule serait plutôt (Mn,Fe2+,Mg)(Al,Fe3+)2O4. (fr)
