Basalt - Wikipedia

Basalt (US: / b ə ˈ s ɔː l t, ˈ b eɪ s ɒ l t /, UK: / ˈ b æ s ɔː l t, ˈ b æ s əl t /) is a mafic extrusive igneous rock formed from the rapid cooling of magnesium-rich and iron-rich 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 ...

Basalt: Igneous Rock - Pictures, Definition, Uses & More

Accessory minerals present in relatively minor amounts include iron oxides and iron-titanium oxides, such as magnetite, ulvospinel, and ilmenite. Because of the presence of such oxide minerals, basalt can acquire strong magnetic signatures as it cools, and paleomagnetic studies have made extensive use of basalt.
