Pyroxenes are inosilicate minerals with single chains of silica tetrahedra and various cations. They have different crystal systems, formulas and names depending on their composition and structure.
Pyroxene is a group of dark-colored rock-forming minerals found in igneous and metamorphic rocks. Learn about their chemical composition, crystal structure, and various uses, such as gemstones, lithium ore, and construction materials.
Pyroxene is a set of rock-forming inosilicate minerals with various chemical compositions and crystal structures. Learn about the nomenclature, properties, occurrence and uses of pyroxene minerals, such as augite, diopside, jadeite and spodumene.
Pyroxene, any of a group of important rock-forming silicate minerals of variable composition, among which calcium-, magnesium-, and iron-rich varieties predominate. Pyroxenes are the most significant and abundant group of rock-forming ferromagnesian silicates. They are found in almost every variety
Pyroxene was originally what might now be called "augite", but the name has been raised as a group name of structurally and chemically similar minerals. A large group of inosilicate (chain silicate) minerals with the general formula ADSi 2 O 6. It is divided into the Clinopyroxene Subgroup (monoclinic) and the Orthopyroxene Subgroup (orthorhombic).
Pyroxene is a group of related silicate minerals that form in igneous and metamorphic rocks. Learn about its properties, subgroups, varieties, uses and geologic importance.
Pyroxene is a group of rock-forming silicate minerals with a chain structure and various cation compositions. Learn about the chemistry, nomenclature, and examples of pyroxene minerals in igneous and metamorphic rocks.
Pyroxenes are silicate minerals with the general formula (Ca,Na,Mg,Fe) (Mg,Fe,Al) (Si,Al) 2 O 6. They have various end members and colors, and can be found in igneous and metamorphic rocks. Learn about their properties, structures, and compositions with examples and diagrams.
Pyroxenes are a group of single chain silicate minerals with the general formula ABSi 2 O 6. They are common in meteorites and igneous rocks, and have two cleavages at roughly 90°. Learn about their occurrence, identification, and minerals in this group.
Pyroxenes are chain silicates with general formula XYSi2O6 that occur in many igneous and metamorphic rocks. Learn about their crystal structure, chemical composition, optical properties, and the pyroxene quadrilateral that shows the solid-solution between orthopyroxenes and clinopyroxenes.
