Chemical composition Olivine, a silicate mineral, comes in two basic flavors, iron or magnesium. The iron variant is called fayalite (Fe 2+2 SiO 4 ). The magnesium variant is forsterite (Mg 2 SiO 4 ). Both are often found in the same sample of olivine. Most olivines found in mare basalts contain 20%-70% fayalite (Lunar Sourcebook, 130).

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.
