Description
One of the major classes of silicate minerals. Amphiboles, in general, are a series of doubly hydrated silicates containing either sodium, calcium, magnesium, iron, or aluminum. They are distinguished from pyroxenes, 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. Amphiboles are commonly found in both igneous and metamorphic rocks. Examples of some amphibole minerals are: hornblende, glaucophane, amphibolite, actinolite, and tremolite.
