• Wadsleyite - Wikipedia

    en.wikipedia.org/wiki/Wadsleyite Wadsleyite is a high-pressure phase of polymorphous Mg 2 SiO 4. An orthorhombic mineral with the formula β-Mg 2 SiO 4, it was first found in nature in the Peace River meteorite from Alberta, Canada. It is formed by a phase transformation from forsterite ...

    www.chemeurope.com/en/encyclopedia/Wadsleyite.html Wadsleyite is a high-pressure polymorph of olivine, an orthorhombic mineral found in the Peace River meteorite in Alberta, Canada. In the phase transformations from Mg 2 SiO 4-Fe 2 SiO 4 (forsterite-fayalite), olivine is transformed to wadsleyite β-Mg 2 SiO 4 and then to a spinel-structured γ-Mg 2 SiO 4 with increasing pressure. This series of transformations is thought to occur during an ...

Experimental data indicate that wadsleyite should transform to a more densely packed spinel structured phase (γ phase) at equivalent burial depths of 520 km. This mineral, known as ringwoodite, has the same composition as Mg-rich olivine, but the crystallographic structure of spinel.
