Olivine belongs to the olivin-groupe whose end-members are calcio-olivine and tephroite. Forsterite is a magnesium silicate; fayalite an iron silicate. If commonly is spoken of olivine, it is usually a more or less iron-rich forsterite. The color of olivine is generally yellowish green, olive green to black. You will find much more interesting details in our portrait about this common mineral series. Written and investigated by Peter Seroka. (Article in german) |
