Basalt is known for its dark color, typically ranging from black to dark gray, and its fine-grained texture. It is composed mostly of minerals such as pyroxene, plagioclase feldspar, and sometimes olivine. Basalt can have a range of compositions, but it is typically rich in iron and magnesium, and low in silica.
