- Basalt - Wikipedia
Basalt (UK: ˈbæsɒlt, - ɔːlt, - əlt ; [1][2] US: bəˈsɔːlt, ˈbeɪsɔːlt ) [3] 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

Basalt is one of the most common rock types on Earth, and it can be found in various locations around the world, both on land and under the ocean floor Basalt is known for its dark color, typically ranging from black to dark gray, and its fine-grained texture

Basalt, extrusive igneous (volcanic) rock that is low in silica content, dark in color, and comparatively rich in iron and magnesium Basalts may be broadly classified on a chemical and petrographic basis into two main groups: the tholeiitic and the alkali basalts

What is basalt, and what does it look like? Basalt rock is fine-grained, dark-colored volcanic rock with essentially Mg-rich plagioclase and augite It is basic or low in silica (42-52 wt %) mafic (Mg- and Fe-rich) rock, with relatively low amounts of total alkalis (Na 2 O and K 2 O)
