Basalt - Igneous rocks

Basalt is a major rock type that occurs in virtually every tectonic setting. Basalt is clearly the most common volcanic rock on Earth and basaltic rocks (including gabbro, diabase and their metamorphosed equivalents) are the most common rocks in the crust 2.Basalt is also common on the Moon and other rocky planets of the Solar System.

What is 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.It has a composition similar to gabbro.The difference between basalt and gabbro is that basalt is a fine-grained rock while ...
