Gabbro is a phaneritic, 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 …

Gabbro is a coarse-grained rock that is formed from the slow cooling of magma deep beneath the Earth's surface. Diorite, on the other hand, is also a coarse-grained rock, but it is formed from the cooling of magma that is closer to the surface. Gabbro is a dark-colored rock that is composed mainly of plagioclase feldspar and pyroxene.

Gabbro is an igneous rock which has crystallized deep in the Earth. Since the rock cooled and hardened (and crystallized) deep below the Earth's surface, it will be coarse grained. High pressure is usually found deep below the surface of the Earth. Here, molten material cools very slowly. The igneous rocks produced have large crystals.
