The mineralogy of Nickel

Aug 15, 2020· Orthosilicates. Orthosilicates are minerals consisting of only single SiO 4 4-units. The cations are some other metals. For example, the following minerals are orthosilicates: The Be and Zn ions are tetrahedrally bonded to the oxygen of the silicate in these two minerals: phenacite, Be 2 SiO 4 and willemite, Zn 2 SiO 4.In olivine, (Fe, Mg) 2 SiO 4, the cations are …
