gabbro Gabbro is a medium or coarsegrained rock that consists 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 variable.
Gabbro is an intrusive igneous rock which is chemically equivalent to plutonic Basalt. These rocks are composed of many distinct minerals. The process of formation of rocks is different for various rocks. Rocks are quarried from many years for various purposes.
A soil of very close texture, the gabbro, is found, most largely in the northeast. It appears to consist chiefly of gabbro, peridotite, serpentine and other very basic eruptive rocks, which are .
Look at other dictionaries: Gabbro — (pronEng|ˈɡæbrəʊ) is a dark, coarse grained, intrusive igneous rock chemically equivalent to basalt. It is a plutonic rock, formed when molten magma is trapped beneath the Earth s surface and cools into a crystalline mass.
Gabbro refers to a large group of dark, coarsegrained, intrusive mafic igneous rock chemically equivalent to Basalt. Because of its special hardness and strength, chemical and physical properties, Gabbro is a very suitable material for a wide range of construction and engineering projects.

Gabbro is the rock that forms layers on oceanic plates. Some variants are known by the trade name "black granite," mainly for countertops and gravestones. It is otherwise unremarkable to the layman.
Apr 25, 2017· Gabbro Rock. These rocks, which are primarily formed from oceanic crust, are high in ferromagnesian content. In addition to these iron silicates and magnesium, gabbro primary mineral content includes calciumplagioclase feldspar and pyroxene. Smaller amounts of olivine and amphibole may also be found within gabbro.
gabbro Igneous rocks: Gabbro ( / ˈ ɡ æ b r oʊ /) refers to a large group of dark, often phaneritic (coarsegrained), mafic intrusive igneous rocks chemically equivalent to basalt. It forms when molten magma is trapped beneath the Earth's surface and slowly cools into a holocrystallinemass.

Gabbros: CoarseGrained Mafic Rocks. This gabbro is roughly half pyroxene and half plagioclase. Pyroxene is typically duller and more blocky than hornblende, but most important are the cleavages intersecting at 90°. Click here to get a superclose up that shows the long, narrow rectangles (laths) typical of plagioclase.
Igneous rocks form from the cooling of magma molten materials in the earth's crust. The terminology Igneous means fire or heat. In this sense, igneous rocks are formed when molten rock (magma) solidifies either underneath the earth crust to form plutonic (intrusive) igneous rocks or on the surface of the earth to form volcanic (extrusive) igneous rocks.
Gabbro is a dense rock that is greenish or darkcolored and comprises varied percentages of pyroxene, plagioclase feldspar, amphiboles, and olivine. Where olivine is present in large quantities, the rock is termed olivine gabbro. A finer grained rock with the same composition as gabbro is termed diabase.
Gabbro is a rock found along midocean ridges and ancient mountains composed of raised oceanic crust. It is formed when magma cools within the Earth's crust. Gabbro has the same geological composition as basalt. Unlike basalt, however, gabbro never makes it to the surface of the Earth before cooling.
About Gabbro Hide. A group of basic intrusive igneous rocks composed principally of basic plagioclase (commonly labradorite or bytownite) and clinopyroxene (augite), with or without olivine and orthopyroxene; also, any member of that group. It is the approximate coarse grained/intrusive equivalent of .
Il gabbro è una roccia magmatica intrusiva macrocristallina, formata principalmente da plagioclasio e gabbro è il corrispondente intrusivo del basalto, roccia ignea effusiva, e del diabase, roccia ignea subvulcanica o nome di questa roccia fu dato dal geologo Christian Leopold von Buch dal nome della località omonima in provincia di Livorno in Toscana
Gabbro forms from molten rock, called magma, that rises out of the mantle and hardens deep within the crust.

Types of plutonic rocks. A common type of mafic plutonic rock is gabbro. Gabbro commonly forms at midoceanic ridges. It can also form wherever there is an especially mafic magma, such as the oceans of molten rock which once existed on the Moon after the large impacts that formed the lunar maria.
