  • Mafic Rocks: Definition, Characteristics & Examples (Basalt)
    A classic example of a mafic rock is basalt.

    Here's why:

    * Composition: Basalt is rich in magnesium (Mg) and iron (Fe), which are the defining characteristics of mafic rocks.

    * Color: It's typically dark gray to black due to its high content of dark minerals like pyroxene and olivine.

    * Texture: Basalt is often fine-grained, meaning its crystals are too small to be seen with the naked eye. This is because it cools quickly, giving the minerals little time to grow.

    * Occurrence: Basalt is a common volcanic rock found on the ocean floor, in volcanic arcs, and in some continental settings.

    Other examples of mafic rocks include:

    * Gabbro: A coarse-grained, intrusive equivalent of basalt.

    * Diabase: A fine-grained, intrusive rock that is similar to gabbro but has a more elongated grain structure.
