WebAug 5, 2024 · Fe 2 SiO 4, an end member of Mg-rich (Mg,Fe) 2 SiO 4 olivine is a major mineral in Earth’s upper mantle. The investigation of lattice dynamical properties of spinel form of magnesium-iron orthosilicate, (Mg,Fe) 2 SiO 4, is of high interest due to its geophysical importance. WebIsolated orthosilicate anions have the formula SiO4− 4. A common mineral in this group is olivine ( (Mg,Fe)2SiO4 ). Two or more silicon atoms can share oxygen atoms in various ways, to form more complex anions, such as pyrosilicate Si 2O6− 7 . Chains [ edit] Depiction of a metasilicate chain, emphasizing the tetrahedral silicate subunits.
WebFerro means iron and magnesian refers to magnesium. The crystal structure of olivine is built from independent silica tetrahedra. Minerals with independent tetrahedral structures are called neosilicates (or orthosilicates). In addition to olivine, other common neosilicate minerals include garnet, topaz, kyanite, and zircon.
