Wadsleyite
A valid IMA mineral species

Formula:
Mg4O(Si2O7)
Although the formula is typically written as β-Mg2SiO4 to emphasize its polymorphic relationship to forsterite, wadsleyite is actually a sorosilicate and not a member of the olivine group. This formula format also better illustrates where hydration of the bridging O occurs in "hydrous wadsleyite".
Colour:
Light grayish brown
Specific Gravity:
3.84 (Calculated)
Crystal System:
Orthorhombic
Name:
It was proposed by Ringwood and Major (1970), who first made synthetic material, that if it was ever found in nature, it should be named after A.D. Wadsley.
Named by G.D. Price, A. Putnis, S.O. Agrell, and D.G.W. Smith in 1982 in honor of David Arthur Wadsley (1 August 1918, Hobart, Tasmania, Australia - 6 January 1969 Canberra, Australian Capital Territory, Australia), Australian solid-state chemist and crystallographer, former research scientist of the Commonwealth Scientific and Industrial Research Organization (CSIRO), Australia, for his significant contributions to crystallography, including the concept of crystallographic shearing.

Type Locality:
Polymorph of:
The orthorhombic, high-pressure polymorph of Ringwoodite and Forsterite (a member of the Olivine group of minerals). Initially found in the Peace River meteorite (from Alberta, Canada), it is thought to be formed from the transformation of Olivine during an extraterrestrial shock event (eg meteorite impact). It is known to be a stable and probably the most abundant phase in the transition zone of the Earth's upper mantle (between 400 and 525km depth).
Recent lab experiments, published in 2009, led by Thomas Ahrens at the California Institute of Technology (Caltech) have been able to replicate the formation of Wadsleyite by launching a high-velocity tantalum projectile at a sample containing magnesium oxide and silicon dioxide (Quartz).
Coupled substitution of Fe3+ and H+ for Si is possible, as shown for a synthetic, hydrous material (Kawazoe et al., 2016).
