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

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 ...

Gabbro: Igneous Rock - Pictures, Definition & More

The word "basalt" is used because the rocks of the oceanic crust have a "basaltic" composition. However, only a thin surface veneer of oceanic crust is basalt. The deeper rocks of the oceanic crust are generally coarser-grained gabbro. Basalt occurs at the surface of the crust because the rocks there have cooled quickly.

Basalt Rock Properties and Uses - ScienceStruck

Most basalt rocks are primarily composed of the minerals pyroxene and feldspar. These rocks are formed due to lava flow. It is a type of rock that is abundantly found in the crust of the Earth, and although now found very commonly on land, most ocean floor areas are underlain with basalt that covers a large percentage of the Earth.

Basalt: Mineral information, data and localities.

A mafite or basaltoid containing mostly calcic plagioclase, clinopyroxene +/- olivine, foids, oxides and rarely quartz. A general term for fine-grained, mafic (dark-colored) igneous rocks, commonly extrusive (volcanic) but locally intrusive (e.g., as dikes or pipes), composed chiefly of plagioclase and clinopyroxene; the fine-grained equivalent of gabbro.
