Description
One of the major classes of silicate minerals. Pyroxenes, in general, a series of doubly hydrated silicates usually containing either calcium, magnesium, or iron. They are distinguished from amphiboles, a second major class, by their cleavage planes. Amphiboles have cleavage angles of 56 and 124 degrees while pyroxenes have cleavage angles of 5 and 93 degrees. Pyroxenes are commonly found in both Igneous and Metamorphic rocks. Examples of some Augite, Enstatite, Diopside, pyroxenite, Jadeite, spudomene, and Rhodonite.
