• Forsterite - Wikipedia

    en.wikipedia.org/wiki/Forsterite Forsterite-rich olivine is a common crystallization product of mantle-derived magma. Olivine in mafic and ultramafic rocks typically is rich in the forsterite end-member. Forsterite also occurs in dolomitic marble which results from the metamorphism of high magnesium limestones and dolomites.

Small amounts of fayalite are present in many volcanic rocks in which sodium is more common than potassium. The forsterite-fayalite minerals also occur in dolomitic limestones, marbles, and metamorphosed iron-rich ...

  • FORSTERITE (Magnesium Iron Silicate)

    www.galleries.com/Forsterite Forsterite is named for the German naturalist, Johann Forster. It is one of two minerals that are simply known as olivine. The other mineral is fayalite. Fayalite is the iron rich member with a pure formula of Fe 2 SiO 4. Forsterite is the magnesium rich member with a pure formula of Mg 2 SiO 4. The two minerals form a series where the iron and magnesium are substitutable for each other ...

    www.alexstrekeisen.it/english/meta/forsteritemarble.php Forsterite marble The term marble in geology is restricted to metamorphic rocks in which the carbonate minerals have recrystallized. This process generally increases the average grain size, which gives marble its sparkling appearance. The word "marble" derives from the Greek (màrmaron) "crystalline rock", "shining stone”.
