Wadsleyite is an orthorhombic mineral with the formula β-(Mg,Fe)2SiO4. It was first found in nature in the Peace River meteorite from Alberta, Canada. It is formed by a phase transformation from olivine (α-(Mg,Fe)2SiO4) under increasing pressure and eventually transforms into spinel-structured ringwoodite (γ-(Mg,Fe)2SiO4) as pressure increases further. The structure can take up a limited amount of other bivalent cations instead of magnesium, but contrary to the α and γ structures, a β structure with the sum formula Fe2SiO4 is not thermodynamically stable. Its cell parameters are approximately a = 5.7 Å, b = 11.71 Å and c = 8.24 Å.

  • La wadsleyita és un mineral de la classe dels silicats. Rep el seu nom en honor de David Arthur Wadsley (1918-1969), químic i cristal·lògraf australià, per les seves contribucions significatives a la cristal·lografia, incloent el concepte de cisallament cristal·logràfic. (ca)
  • Wadsleyita silikato motako minerala da. (eu)
  • La wadsleyita es un mineral de la clase de los silicatos, y dentro de esta pertenece a los sorosilicatos, grupo del olivino. Fue descubierta en 1982 analizando el meteorito "Peace River" que en 1963 explotó sobre el cielo de Alberta (Canadá), siendo nombrada así en honor de David A. Wadsley, químico cristalógrafo australiano.​ Un sinónimo es su clave: IMA1982-012. (es)
  • La wadsleyite è un minerale scoperto nel 1966 il cui nome è stato attribuito in onore del cristallografo A. D. Wadsley (1918-1969). Questo minerale fa parte del gruppo dell'olivina. È polimorfo della ringwoodite e della forsterite. (it)
  • Вадслеит или Уэдслиит (англ. wadsleyite) — высокобарная полиморфная модификация оливина. Является минералом ромбической сингонии. Впервые был обнаружен в хондрите Peace River в Канаде. (ru)
  • Wadsleyit ist ein Mineral aus der Abteilung der Gruppensilikate innerhalb der Mineralklasse der „Silikate und Germanate“ mit der idealisierten chemischen Zusammensetzung Mg2[SiO4] und ist damit chemisch gesehen ein Magnesium-Silikat. Wadsleyit kristallisiert im orthorhombischen Kristallsystem, entwickelt aber nur mikrokristalline Aggregate mit Korngrößen bis maximal 5 µm. Bei Wasseraufnahme von mehr als 1,5 % ändert Wadsleyit sein Kristallsystem und wird monoklin. (de)
  • La wadsleyite est un minéral de la famille des silicates (sous-famille des sorosilicates), de formule chimique (Mg,FeII)2SiO4. Son nom est un hommage au minéralogiste australien Arthur David Wadsley (1918-1969). La wadsleyite est un polymorphe de haute pression de l'olivine. À plus haute pression elle est remplacée par la ringwoodite. La wadsleyite a été trouvée dans certaines météorites, où elle a été formée lors d'un choc (à l'arrivée sur Terre ou antérieurement). (fr)
