Gabbro

Gabbro Gabbro is a dense, mafic intrusive rock. It generally occurs as batholiths and laccoliths and is often found along mid-ocean ridges or in ancient mountains composed of compressed and uplifted oceanic crust. Gabbro is the plutonic equivalent of basalt.

Gabbro Facts - Softschools.com

Gabbro is an igneous rock, is coarse-grained, dark-colored and intrusive. It is usually composed mainly of the minerals, calcium-rich plagioclase feldspar and augite. It may also contain small amounts of olivine and orthopyroxene, but very little amounts of quartz, unlike most igneous rocks. It is the most abundant rock in deep oceanic crust, and can be black or dark green in color.

Gabbro - Wikipedia

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. Much of the Earth's oceanic crust is made of gabbro, formed at mid-ocean ...

Gabbro - Simple English Wikipedia, the free encyclopedia

Gabbro is a large group of dark, coarse-grained, igneous rocks. They are chemically equivalent to basalt. The rocks are plutonic, formed when molten magma is trapped under the Earth's surface and cools into a crystalline mass. Most of the Earth's surface has gabbro in the oceanic crust, produced by basalt magmatism at mid-ocean ridges.
