Pyroxene is a group of closely related inosilicate minerals that are commonly found in igneous and metamorphic rocks. They are classified into two main mineral series: the orthopyroxenes and the clinopyroxenes. Pyroxenes are essential components of mafic rocks such as basalt and gabbro, and they also occur in some ultramafic rocks.
Composition
Pyroxenes are composed of single chains of silica tetrahedra linked together by metal cations such as calcium, magnesium, iron, and sodium. The most common pyroxenes are rich in iron and magnesium, giving them a dark green to black color. However, pyroxenes can also be found in lighter colors depending on their composition.
Physical Properties
Pyroxenes have a prismatic crystal habit with two cleavage directions at nearly right angles. They have a glassy to dull luster and a hardness ranging from 5 to 7 on the Mohs scale. Pyroxenes are typically found in elongated prismatic crystals or as fibrous aggregates.
Occurrences
Pyroxenes are commonly found in igneous and metamorphic rocks, where they form as primary minerals during the crystallization of magma. They can also be found as secondary minerals in hydrothermal veins and contact metamorphic rocks. Some pyroxenes are important mineral indicators in the study of rock formations and geological history.
In summary, pyroxene is a significant group of minerals with diverse compositions and properties that play a crucial role in the formation and classification of various rock types. From igneous to metamorphic rocks, pyroxenes are key components that provide valuable insights into the Earth's geological processes.
