pyroxeny
Pyroxeny is a term used to describe a group of silicate minerals that share a common crystal structure and chemical composition. The name "pyroxene" is derived from the Greek words "pyro," meaning fire, and "xenos," meaning stranger, reflecting the mineral's fire-like color and its presence in igneous rocks. Pyroxenes are single-chain inosilicates, meaning they have a single tetrahedral chain in their crystal structure. This structure gives them a characteristic prismatic or columnar habit.
The general chemical formula for pyroxenes is XY(Si,Al)2O6, where X is typically a divalent cation such as
Pyroxenes are widespread in igneous rocks, particularly in mafic and ultramafic rocks. They are also found
In addition to their geological significance, pyroxenes have various industrial applications. For example, they are used
