What Is Basalt Rock

Basalt is a mafic extrusive igneous rock formed from the rapid cooling of magnesiumrich and ironrich lava exposed at or very near the surface of a terrestrial planet or a moon More than 90 of all volcanic rock on Earth is basalt Basalt lava has a low viscosity due to its low silica content resulting in rapid lava flows that can spread over great areas before cooling and solidification Flood
