An important rock-forming mineral of igneous and metamorphic rocks, pyroxene is not a specific mineral, but an informal name used for a number of group of related minerals.

Pyroxene is the name of a group of dark-colored rock-forming minerals found in igneous and metamorphic rocks throughout the world. They form under conditions of high temperature and/or …

Pyroxene was believed to be an impurity in the glass, and therefore a "stranger to fire" and not formed by the action of heat. Pyroxene was originally what might now be called "augite", but the name has …

The pyroxenes are a group of important rock-forming silicate minerals found in many igneous and metamorphic rocks. They share a common structure comprised of single chains of silica tetrahedra …

The pyroxene group is a large group of single chain silicate minerals with the general formula ABSi 2 O 6. The group gets its name from the Greek words for Fire and Silver.

Pyroxenes are single-chain silicates with the general formula XYSi2 O 6, where X and Y are either both divalent cations (mainly Ca, Fe, Mg), or mono- (Na, Li) and trivalent cations (Al, Fe) respectively.

Feb 23, 2025 · Pyroxene refers to a group of silicate minerals commonly found in many rocks, especially in igneous and metamorphic types. These minerals are known for their high melting points and …

The pyroxene group includes minerals that form in both the orthorhombic and monoclinic crystal systems. Orthorhombic pyroxenes are referred to as orthopyroxenes, and monoclinic pyroxenes are …
