Basalt: Composition, Properties, Types, Uses Basalt constitutes the Earth's most abundant igneous rock type, estimated to comprise approximately 70% of the planet's crust. What is Basalt Basalt is defined as a fine-grained, dark-colored igneous rock composed mainly of plagioclase and pyroxene minerals, with or without olivine.
Basalt is one of Earth’s most abundant and widely distributed volcanic rocks, known for its dark color and dense structure. Formed from the rapid cooling of lava at or near the Earth’s surface, basalt is essential in the geological makeup of ocean floors, continental crust, and even planetary bodies beyond Earth. Beyond its geological importance, basalt has a range of applications in ...

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. Rapid-cooling, fine-grained basalt ...
Basalt is a dark-colored, fine-grained, igneous rock composed mainly of plagioclase and pyroxene minerals. It most commonly forms as an extrusive rock, such as a lava flow, but can also form in small intrusive bodies, such as an igneous dike or a thin sill.
