Gabbro Facts for Kids

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.

Gabbro - Wikipedia

Gabbro is dense, greenish or dark-colored and contains pyroxene, plagioclase, and minor amounts of amphibole and olivine.. The pyroxene content is mostly clinopyroxene, generally augite, but small amounts of orthopyroxene may also be present. If the amount of orthopyroxene is more than 95% of the total pyroxene content (5% or less clinopyroxene content), then the rock is termed norite.

Norite - Wikipedia

Norite is a mafic intrusive igneous rock composed largely of the calcium-rich plagioclase labradorite, orthopyroxene, and olivine.The name norite is derived from Norge, the Norwegian name for Norway.. Norite also known as orthopyroxene gabbro.Norite may be essentially indistinguishable from gabbro without thin section study under the petrographic microscope.

Gabbro and Basalt are RelatedGabbros are equivalent in composition to basalts. The difference between the two rock types is their grain size. Basalts are extrusive igneous rocks that cool quickly and have fine-grained crystals. Gabbros are intrusive igneous rocks that cool slowly and have coarse-grained crystals.

Gabbro - Assignment Point

Gabbro occurs when the liquid rock is cooled very slowly over a long period of time in the underground. This is an intrusive magmatic rock and is close to the very hot core of the world, which is why it takes longer to cool, and therefore the rock is visibly very different from the opposite of the basalt.

Pictures and Descriptions of Igneous Rock Types

Gabbro makes up most of the deep part of the oceanic crust, where melts of basaltic composition cool very slowly to create large mineral grains. That makes gabbro a key sign of an ophiolite, a large body of oceanic crust that ends up on land. Gabbro is also found with other plutonic rocks in batholiths when bodies of rising magma are low in silica.

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.
