Basalt
Basalt is an aphanitic (finegrained) extrusive igneous rock formed from the rapid cooling of lowviscosity 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 cooling, finegrained basalt is chemically equivalent to slowcooling, coarsegrained gabbro The eruption of basalt lava is observed bHow is basalt mined? From Volcano to Roads to Decorations: Basalt is a hard, dense igneous rock formed from volcanic activity as cooled lava We can find it on the black How is basalt mined? HomeworkStudy
