Granite and gabbro are both types of igneous rocks that solidify from molten material beneath the Earth's surface. They both contain large mineral crystals, with granite being a coarse-grained rock and gabbro being a fine-grained rock. Additionally, both rocks are commonly used in construction and as decorative stone.

What minerals are in granite but not gabbro?
Granite typically contains more quartz and alkali feldspar than gabbro. Additionally, granite may have higher concentrations of minerals like muscovite, biotite, and amphiboles compared to gabbro.
Granite and gabbro have?
similar mineral compositions but differ in their texture. Granite is coarse-grained, consisting of larger mineral grains that are visible to the naked eye, while gabbro is fine-grained with smaller mineral grains. Additionally, granite is typically found in continental crust, whereas gabbro is more common in oceanic crust.
Does gabbro have a higher silica content than granite?
No, gabbro has a lower silica content than granite. Gabbro is classified as a mafic rock with silica content ranging from 45-52%, while granite is a felsic rock with higher silica content ranging from 65-75%.
What are some examples of intrusive igneous rock?
Granite and gabbro are the two biggies, granite being formed underground by felsic magma, and gabbro being formed underground by mafic magma. Diorite and peridotite are two others.
What is the difference between granite and gabbro?
Granite is an igneous rock with a coarse-grained texture that is typically light in color and contains quartz, feldspar, and mica minerals. Gabbro is also an igneous rock but has a finer-grained texture and is dark in color, composed mainly of plagioclase feldspar and pyroxene minerals. Overall, granite is lighter in color and coarser-grained compared to gabbro.
How does a Granite rock and a Gabbro rock differ from each other?
The counterpart of Granite is Rhyolite,the counterpart of Gabbro is Basalt. Gabbro is mafic(Dark coloured) ,Granite is felsic (light coloured) Granite forms from magma of Granitic composition while Gabbro forms from magma of Basaltic composition.

Do granite and gabbro have similar crystal size?
Granite and gabbro both contain large crystals, but gabbro typically has larger crystals due to its slower cooling rate beneath the Earth's surface compared to granite which cools at or near the surface.
It is sometimes called black granite?
gabbro
Where do granite and gabbro crystallize?
Deep underground.
Do Granite and Gabbro have the same chemical composition?
No. Gabbro is a mafic rock (magnesium and iron silicates) while granite is a felsic rock (referring to lighter elements such as potassium in feldspar). Felsic rock contains fewer heavy elements than mafic rocks. The chemical equivalent to gabbro is basalt, as both are mainly pyroxene and plagioclase feldspar. The difference is that gabbro is intrusive rock and basalt is extrusive.
What is lighter gabbro or granite?
Gabbro is typically lighter than granite because it has a higher density due to its composition of minerals such as pyroxene and plagioclase feldspar. Granite is composed of minerals like quartz, feldspar, and mica, which generally have lower densities.
What is the use gabbro?
Gabbro is oftentimes used in ornamental or decorative stones, most notable as "black granite" in graveyard headstones.
What are some examples of intrusive igneous rock?
Granite and gabbro are the two biggies, granite being formed underground by felsic magma, and gabbro being formed underground by mafic magma. Diorite and peridotite are two others.
What are five intrusive rocks?
Granite, gabbro, and diorite are three that I can think of.
