What do gabbro and granite have in common?
Intrusive igneous rocks like granite and gabbro have some things in common. They: 1. Are large grained – magma cools very slowly beneath the Earth’s surface so the crystals in the rock have a long time to grow.
Does granite and gabbro have a similar mineral composition?
Granites and rhyolites consist predominantly of quartz and potash feldspar; gabbros and basalts, predominantly of pyroxene and plagioclase feldspar. Other rock types have intermediate mineral compositions.
What rock has the same texture as gabbro?
Norite is a mafic intrusive igneous rock with color ranging between light and dark gray and brown. The rock is indistinguishable from gabbro, other than the type of pyroxene under the microscope. It is composed of Ca-rich Plagioclase (Labradorite), Mg-rich Orthopyroxene/Hypersthene (Enstatite), and Olivine.
What rock has the same texture as granite?
Chemical composition
The medium-grained equivalent of granite is microgranite. The extrusive igneous rock equivalent of granite is rhyolite.
How would you describe the texture of granite?
Granites usually have a coarse texture (individual minerals are visible without magnification), because the magma cools slowly underground, allowing larger crystal growth. Granites are most easily characterized as light colored and coarse grained as a result of cooling slowly below the surface.
What is the relationship between a granite and a gabbro?
In simple terms, gabbro is just the cooled magma chamber for the basaltic flows that erupt at the surface. In the same respect, granite is the cooled (and exposed) magma chamber for extrusive rhyolite.

What is the relationship between a granite and a gabbro quizlet?
Granite is felsic and lighter colored – more white and pinkish. Gabbro has Anorthite &Pyroxene. Gabbro is mafic and darker colored – may be greenish. Diorite has Plagioclase, Biotite, Amphibole in mineral; and would have roughly equal amounts of these minerals.
What determines the texture of an igneous rock?
The texture of an igneous rock (fine-grained vs coarse-grained) is dependent on the rate of cooling of the melt: slow cooling allows large crystals to form, fast cooling yields small crystals.
Is granite coarse or fine grained?
Granite is a coarse-grained rock composed of aluminosilicate minerals that crystallizes slowly and at much higher temperatures than basalt.

Granite is a coarse-grained igneous rock with average grain size ranging from 1 to 25 millimeters. Gabbro is generally coarse grained, with crystals in the size range of 1 mm or greater.
What is the characteristics of gabbro?
Gabbro 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.
What is the difference between gabbro and diorite?
The difference between gabbro and diorite lies in the composition of plagioclase, sodic in diorites (An5–50; oligoclase – andesine), calcic in gabbros (An50–100; labradorite – bytownite – anorthite). In the field, a light-colored gabbroid rock is more likely to be a diorite, rather than a gabbro.
What do gabbro and basalt have in common?

What type of igneous rock is gabbro?
Gabbro (/ˈɡæb. roʊ/) 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.
How are granite and granitic gneiss similar?
Geologically speaking, granite and gneiss are similar, so lumping them together is a reasonable thing to do. In simplified terms, you can think of gneiss as a metamorphic version of granite. Both gneiss and granite are made of feldspars, quartz, mica, and smaller amounts of dark colored minerals like hornblende.
Why does gabbro weather faster than granite?

Weathering Behavior | Rocks containing olivine, pyroxene, and plagioclase generally weather faster. |
Is gabbro coarse grained?
gabbro, 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 variable.
How does the texture of gabbro compare to that of obsidian?
How does the texture of gabbro compare to that of obsidian? Gabbro has large crystals, in contrast to obsidian’s crystals, which are very small. Is gabbro an intrusive or extrusive igneous rock?
Why is granite not dense?
Rock Densities
Rock density is very sensitive to the minerals that compose a particular rock type. Sedimentary rocks (and granite), which are rich in quartz and feldspar, tend to be less dense than volcanic rocks.
What is the aphanitic equivalent of gabbro?
Basalt is the aphanitic (fine-textured) extrusive equivalent of gabbro. From the Latin word “pumex”, meaning “pumice”. A vesicular, glassy volcanic rock, generally of rhyolite composition (felsic). Often light in color.

How does gabbro compare to basalt?
Gabbro is a type of intrusive rock while basalt is a type of extrusive rock. The main difference between gabbro and basalt is that gabbro forms deep beneath the Earth’s surface, whereas basalt forms at or very near the surface of the planet.
What is texture in rocks?
In rock: Texture. The texture of a rock is the size, shape, and arrangement of the grains (for sedimentary rocks) or crystals (for igneous and metamorphic rocks). Also of importance are the rock’s extent of homogeneity (i.e., uniformity of composition throughout) and the degree of isotropy.
Why do igneous rocks have different textures quizlet?
What affects the texture of an igneous rock? The texture of an igneous rock is determined by the cooling history of the magma from which it formed. Magmas that cool slowly form large crystals, and those that cool quickly form small crystals.
What type of rock is granite?
Granite is an igneous rock that forms when magma cools relatively slowly underground. It is usually composed primarily of the minerals quartz, feldspar, and mica. When granite is subjected to intense heat and pressure, it changes into a metamorphic rock called gneiss.
