  • 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 | Definition, Properties, Facts | Britannica
    basalt, extrusive igneous (volcanic) rock that is low in silica content, dark in colour, and comparatively rich in iron and magnesium Some basalts are quite glassy (tachylytes), and many are very fine-grained and compact
  • Basalt | Properties, Formation, Composition, Uses
    Basalt is a type of volcanic rock that is formed from the solidification of molten lava It is an igneous rock, meaning it is formed through the cooling and solidification of magma or lava 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
  • Basaltic Lava Flows - U. S. National Park Service
    Basaltic lava flows are more than just seas of black rock Solidified flows have features that provide information about their eruptions and emplacement
  • Basalt: Composition, Properties, Types, Uses – Geology In
    Basalt is defined as a fine-grained, dark-colored igneous rock composed mainly of plagioclase and pyroxene minerals, with or without olivine It is formed from the rapid cooling of basaltic lava exposed at or very near the surface of the Earth (extrusive or volcanic rock)

    Basalt is a dark-colored, dense rock composed primarily of plagioclase feldspar and pyroxene It is the most common rock type found in oceanic crust and is an important component of the Earth’s continental crust
  • Basaltic Lava: Types, Composition, Formation, and Landforms
    Basaltic lava, a prevalent volcanic rock on Earth, significantly influences the planet’s surface Known for its fluidity and relatively low viscosity, basaltic lava contributes to forming new landmasses and shaping geological features
  • Mafic or Basaltic Rock - HyperPhysics
    Basalt is a dark gray to black, fine-grained, volcanic rock The fine-grained (aphanitic) texture indicates that it is an extrusive rock, formed at or near the surface from volcanic eruptions It is a major constituent of lava flows on the surface and of the ocean bottoms It is in fact the most common extrusive igneous rock
  • Basalt: Properties, Formation, Uses, and Famous Locations | Complete Guide
    Basalt is one of the most common and widespread igneous rocks on Earth, making up much of the oceanic crust and significant portions of continental crust This dark-colored volcanic rock forms from the rapid cooling of lava at or near the Earth's surface, resulting in a fine-grained texture
