Beard & Hopkinson (2000) note that once all olivine is consumed the oxygen fugacity of infiltrating fluids typically rebounds, and permits a reaction involving methane or CO 2 (equation 2). Minerals of the olivine group are abundant in the earth, the moon, and the stony meteorites. Gem miners find peridot as irregular nodules in some lava flows in the United States, China, and Vietnam and, very rarely, as large crystals lining veins or pockets in certain . Physical Properties. The physical origins of D J and D* and related physical quantities have . Peridot Chemical composition: (MgFe) 2 SiO 4; Class: nesosilicate . Chemical formula. Olivine and quartz have a smooth curved (concoidal) fracture. Physical Properties. Its precise chemical formula is (Fe, Mg)2 SiO4. A comparison of our results with the global seismic model AK135 yields average olivine content near 410 km depth of about 37% and 43% in a dry and wet (1.9 wt % H 2 O) upper mantle, respectively. This page concerns itself with olivine in general. Magnesium-rich olivines are abundant in low-silica mafic and ultramafic igneous rocks and are believed to be the most abundant constituent of the Earth's upper mantle. Density: . Here we report the elastic properties hydrous forsterite (hy-Fo 100) and hydrous olivine (hy-Fo 97) containing what is considered to be the maximum possible concentration of water (0.9 wt% H 2 O) in olivine. Olivine is a solid solution series mineral whose two most common end members are forsterite (Mg) and fayalite (Fe). PHYSICAL PROPERTIES OF PERIDOT. The spokesperson said serpentine rock is "an extremely suitable mineral carbonation feedstock and long-term carbon sink". physical properties to be determined must be determined on individual grains, not on an aggregate of grains. [1] Olivine is an important host of hydrogen in the Earth's upper mantle, and the OH abundance in this mineral determines many important physical properties of the planet's interior. It is the only common igneous mineral with these properties. Go to your rock identification table for further information.
