Basalt is a dark-colored, fine-grained, igneous rock composed

mainly of plagioclase and pyroxene minerals. It most commonly

forms as an extrusive rock, such as a lava flow.

Basalt is Earth's most abundant bedrock, it underlies more of

Earth surface than any other type of rock. It is also abundant on

the Moon. Much of the Moon's surface is underlain by basaltic

lava flows and flood basalts. These areas of the Moon are

known as "lunar maria."

Basalt is used for a wide variety of purposes. It is most commonly

crushed for use as an aggregate in construction projects. Crushed

basalt is used for road base, concrete aggregate, asphalt pavement

aggregate, railroad ballast, filter stone in drain fields and may other

purposes. Basalt is also cut into dimension stone. Thin slabs of

basalt are cut and sometimes polished for use as floor tiles,

building veneer, monuments and other stone objects.
