Basalt - Wikipedia
Basalt is an aphanitic (fine-grained) extrusive igneous rock formed from the rapid cooling of low-viscosity lava rich in magnesium and iron (mafic lava) exposed at or very near the surface of a rocky planet or moon. More than 90% of all volcanic rock on Earth is basalt. Rapid-cooling, fine-grained basalt is chemically equivalent to slow-cooling, coarse-gra… See more

- Basalt is a fine-grained extrusive igneous rock formed from the rapid cooling of low-viscosity lava rich in magnesium and iron1. It is a mafic lava that is exposed at or very near the surface of a rocky planet or a moon1. More than 90% of all volcanic rock on Earth is basalt1. Basalt is a basic (SiO2-poor) volcanic rock that mainly consists of a mixture of calcium-iron-magnesium silicates (pyroxenes) and calcium- and sodium-rich feldspar (plagioclase) as well as usually olivine2.Learn more:✕This summary was generated using AI based on multiple online sources.
