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 … Ver mais Basalt is composed mostly of oxides of silicon, iron, magnesium, potassium, aluminum, titanium,and calcium. Geologists classify igneous rock by its mineral content whenever possible, with the relative volume … Ver mais Earth Basalt is the most common volcanic rock type on Earth, making up over 90% of all volcanic rock on the planet.
