Gabbro: Igneous Rock - Pictures, Definition & More - Geology.com
WEBGabbro is a coarse-grained, dark-colored, intrusive igneous rock. It is usually black or dark green in color and composed mainly of the minerals plagioclase and augite. It is the most abundant rock in the deep oceanic crust. Gabbro has a variety of uses in the construction industry.
Gabbro - Wikipedia
WEBGabbro (/ ˈ ɡ æ b r oʊ / GAB-roh) is a phaneritic (coarse-grained and magnesium- and iron-rich), mafic intrusive igneous rock formed from the slow cooling magma into a holocrystalline mass deep beneath the Earth's surface.
Gabbro | Properties, Formation, Composition, Uses - Geology …
WEBSep 4, 2023 · Gabbro is a type of intrusive igneous rock that is coarse-grained and dark-colored, typically composed of calcium-rich plagioclase feldspar, pyroxene, and sometimes olivine. It is similar in composition to basalt, which is its extrusive equivalent.
Gabbro | Igneous Rock, Mafic Minerals & Plutonic Intrusions
WEBGabbro, any of several medium- or coarse-grained rocks that consist primarily of plagioclase feldspar and pyroxene. Essentially, gabbro is the intrusive (plutonic) equivalent of basalt, but whereas basalt is often remarkably homogeneous in mineralogy and composition, gabbros are exceedingly.
Gabbro - Igneous rocks - Sandatlas
WEBGabbro is a coarse-grained and usually dark-colored igneous rock. It is an intrusive rock. It means that it formed as magma cooled slowly in the crust. Igneous rocks with similar composition are basalt (extrusive equivalent of gabbro) and diabase (the same rock type could be named dolerite or microgabbro instead).

WEBAug 3, 2024 · Gabbro is a dense, coarse-grained igneous rock that forms deep beneath the Earth’s surface as slow-cooling magma solidifies. It shares the same composition as basalt but cools slowly enough for its minerals to grow large and become visible to …
Gabbro Rocks: Identification, Characteristics, Pictures, and More
WEBApr 11, 2024 · Gabbro rocks are igneous rocks that form through the slow cooling of magma beneath the Earth’s surface. Their geological formation involves the crystallization of molten magma rich in iron and magnesium minerals.
Gabbro - Geology is the Way
WEBGabbro is a plutonic igneous rock and the intrusive counterpart of basalt. Gabbros are essentially constituted by Calcium-rich plagioclase (>An50), clinopyroxene (augite, diopside), and iron oxides (ilmenite, magnetite) and may contain accessory olivine, amphibole, orthopyroxene, and spinel.
Gabbro: A Coarse-grained, Dark-Colored Plutonic Rock
WEBJul 21, 2023 · Today, it describes a mafic plutonic igneous rock with mainly calcium-rich plagioclase and pyroxene. Gabbro is a relatively common rock with many uses. It occurs worldwide, mainly in deep ocean crust, continental arcs, intraplate hotspots, and rifts, and less often in island arcs.
Gabbro - Minerals Education Coalition
WEBGabbro 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.
