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 the opposite of granite. Basalt is a mafic (dark coloured minerals rich in iron and magnesium)fine grained rock formed from the rapid cooling and crystallisation of lava above ground. Granite: Pale coloured, felsic, intrusive, coarse grained/porphyritic.asalt is the foundation of oceanic crust. Granite is an intrusive igneous rock made from visible mineral crystals, a result of cooling over a longer period of time under the surface of the Earth. Another difference between basalt and granite include their joints.
