Olivine Group

This page kindly sponsored by John Weidner
Formula:
M2SiO4
M = Ca, Fe, Mn, Ni, Mg
Name:
The evolution of the term "olivine group" is complex. The earliest name given to an olivine group species was chrysolite and was named by Johan Gottschalk Wallerius in 1747, although the name chrysolite was later used by Balthasar Georges Sage in 1777 for what is now known as prehnite. Chrysolite was renamed, olivine, in 1789 by Abraham Gottlieb Werner for the usual olive green color of this mineral (N.B. chrysolite has a similar etymology.) The second member of the group was named tephroite in 1823 by Johann Friedrich August Breithaupt. The common Mg-dominant member of the group was re-named, forsterite, by Serve-Dieu Abailard "Armand" Lévy in 1824. Hemy C. Salmon in 1859 explicitly used "olivine group" to designate minerals which were chemically analogous to "olivine". In the USA, James Dwight Dana and George Jarvis Brush began organizing groups in their "System" and organized the "chrysolite group" in 1868 and that group name was continued into 1892 by Edward Salisbury Dana. The universal acceptance of "olivine group" occurred in the twentieth century. (See also olivine.)
A group of simple orthosilicates. Polymorphous with ringwoodite and wadsleyite.
