Wadsleyite

This page is currently not sponsored. Click here to sponsor this page.
David A. Wadsley
Formula:
(Mg,Fe2+)2(SiO4)
Colour:
Light grayish brown
Specific Gravity:
3.84 (Calculated)
Crystal System:
Orthorhombic
Name:
It was proposed by Ringwood and Major (1970), who first made sythetic material, that if it was ever found in nature, it should be named after A.D. Wadsley.

Named by R.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 - 1969), 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.
Polymorph of:
Olivine Group.

The orthorhombic, high-pressure polymorph of Ringwoodite and Forsterite (a member of the Olivine group of minerals). Initially found in the Peace River meteroite (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).
