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.
Basalt is a commonly extrusive volcanic rock. It is usually grey to black and fine-grained due to rapid cooling of lava at the surface of a planet. Unweathered basalt is black â¦ or grey.Basalt is defined as an igneous rock that contains less than 20% quartz and less than 10% feldspathoid and where at least 65% of the feldspar is in the form of plagioclase.asalt is mainly comprised of calcic plagioclase feldspar and  pyroxene. Olivine can also occur in large amounts in basalt and a  number of other minerals may appear in mino â¦ r amounts.
