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. Olivine and iron-titanium oxides are very common and nepheline, orthopyroxene, or quartz may be present.
The Basalt Fiber History From a volcanic lava to an advanced composite. From Lava to Rock. Basalt is a type of igneous rock formed by the rapid cooling of lava at the surface of a planet. It is the most common rock in the Earth's crust. Basalt rock characteristics vary from the source of lava, cooling rate, and historical exposure to the elements.

Gabbro (/ ˈ ɡ æ b r oʊ /) is a phaneritic (coarse-grained), mafic intrusive igneous rock formed from the slow cooling of magnesium-rich and iron-rich magma into a holocrystalline mass deep beneath the Earth's surface. Slow-cooling, coarse-grained gabbro is chemically equivalent to rapid-cooling, fine-grained basalt.
Basalt is an extrusive igneous rock that is very dark in color. It is the most common type of rock in the Earth's crust and it makes up most of the ocean floor.. It is made of many dark colored minerals such as pyroxene and olivine.Basalt also contains some light colored minerals such as feldspar and quartz, but the amounts are small.
Basalt is a very common igneous rock. In fact it is the most common rock in the Earth's crust.
