Basalt Igneous rocks

Basalt is a very common dark-colored volcanic rock composed of calcic plagioclase (usually labradorite), clinopyroxene ( augite) and iron ore (titaniferous magnetite ). Basalt may also contain olivine, quartz, hornblende, nepheline, orthopyroxene, etc. Basalt is a volcanic equivalent of gabbro. Basalt is a fine-grained and dark-colored rock.
