4.4: Silicate Minerals - Geosciences LibreTexts

2021-8-17  4.4: Silicate Minerals. Minerals are categorized based on their composition and structure. Silicate minerals are built around a molecular ion called the silicon-oxygen tetrahedron. A tetrahedron has a pyramid-like shape with four sides and four corners. Silicate minerals form the largest group of minerals on Earth, comprising the vast majority ...

Mg-Fe Order-Disorder in Ferromagnesian Silicates ...

Abstract. Intracrystalline distribution in silicates has been a subject of interest among geochemists since the classical work of Goldschmidt (1954). 1 The phenomenon of strong Fe 2+-Mg ordering in two of the common rock-forming ferromagnesian silicates, pyroxenes and amphiboles, was discovered in the early sixties through single-crystal X-ray diffraction study.
