WebThe olivine group (Mg,Fe)2 SiO 4, is a group of igneous minerals which is commonly abundant, and quickly weathered, on the Earth's subsurface. Olivine is a mixture of magnesium-rich forsterite (Mg 2 SiO 4) and iron-rich fayalite (Fe 2 SiO 4 ). Forsterite is more common than fayalite ( Klein and Hurlbut, 1993 ). WebChemical Formula. The Garnet Group is composed of several minerals with related chemical formulas. The generic formula for the common Garnets is: X2+3Y3+2Si3O12. X represents Ca, Fe2+, Mn, or Mg. Y represents Al, Cr, or Fe3+. A more comprehensive list can be found in The chemical formula of Garnet.
