  • How to Identify Basalt Sciencing

    Basalt, a volcanic igneous rock, occurs worldwide, but especially in India, Scotland, Greenland, Iceland, Canada and the northwestern United States. Most basalt occurs as lava flows, in narrow dykes or sills. It's the basalt from lava flows that make up the enormous sheets of a lava plateau. This rock is easy to ...

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

    GeologyOverviewFormationLocationsExamplesUsesBasalt 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. It has a composition similar to gabbro. The difference between basalt and gabbro is that basalt is a fine-grained rock while gabbro is a coarse-grained rock. Basalt underlies more of Earth's surface than any other rock type. Most areas within Earth
