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 common form of extrusive igneous rock and forms lava flows, lava sheets and lava plateaus. Extrusive igneous rocks include andesite, basalt, obsidian, pumice, rhyolite, scoria, and tuff. Because the minerals are mostly fine-grained, it is much more difficult to distinguish between the different types of extrusive igneous rocks than between different types of intrusive igneous rocks.
