Basalt (pronounced /bÉËsÉËlt/, /ËbÃ¦sÉlt/, /ËbÃ¦sÉËlt/, or /ËbeÉªsÉËlt/) is a common extrusive igneous (volcanic) rock formed from the rapid cooling of basaltic lava exposed at or very near the surface of a planet or moon. Flood basalt describes the formation in a series of lava basalt flows.
Back to Encyclopedia. Basalt is the most common volcanic rock: It is formed as the volcanic magma erupts onto the surface or even in the water and undergoes a rapid cooling process.It has varying shades of grey to black. The fast cooling process makes the creation of the minerals almost invisible, making it a fine-grained substance.ack to Encyclopedia.
