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.
â¢ Basalt is mostly found on ocean floors, while granite is the crust of earth in all continents. â¢ Basalt is extrusive, while granite is intrusive igneous rock. â¢ Basalt is darker and is composed of magnesium and iron, whereas granite is lighter and is made up of feldspar and quartz. â¢ Basalt is called mafic, while granite is called felsic.
