Granite is defined as a course grained rock that must have plagioclase feldspar, potassium (aka alkali) feldspar, and quartz. Granite can also have a number of secondary minerals like micas or hornblende, but these secondary minerals do not have to be present.

∙ 9y agoGranite's mineral composition is mainly quartz and feldspar. Approximately 80 percent of this igneous rock is made up of these two minerals, The other minerals found in granite are mica and amphibole.

∙ 6y agoGranite is a common and widely occurring type of intrusive, felsic, igneous rock. Granite has a medium to coarse texture, occasionally with some individual crystals larger than the groundmass forming a rock known as porphyry. Granites can be pink to dark gray or even black, depending on their chemistry and mineralogy. Outcrops of granite tend to form tors, and rounded massifs. Granites sometimes occur in circular depressions surrounded by a range of hills, formed by the metamorphic aureole or hornfels.

Is granite the plutonic equivalant of rhyolite?
Yes. Granite and Rhyolite have the same composition.
What minerals does the rock granite always contain?
granite has its composition _ quartz+alkali feldspar
Do diorite and rhyolite have the same chemical composition?
No. Diorite has the same composition as andesite while Rhyolite has the same composition as granite.
What is the average composition of the oceanic crust is thought to approximate?
granite
What is the difference between red granite and granite?
Red granite refers to a type of granite that has a predominantly red color, while granite is a general term for a type of igneous rock that is primarily composed of quartz and feldspar minerals. Red granite is a specific variety of granite distinguished by its color, which can range from pinkish-red to deep burgundy.
What type of composition does granite have?
who cares
What does it mean to have andesitic composition?
Rocks have a composition between that of granite and basalt
Is granite the plutonic equivalant of rhyolite?
Yes. Granite and Rhyolite have the same composition.
How are basalt and granite diffrerent in their origin texture and mineral composition How are the similar?
Basalt is extrusive, formed from cooling lava, and has a fine-grained texture with minerals like pyroxene and plagioclase feldspar. Granite is intrusive, formed from cooling magma underground, and has a coarse-grained texture with minerals like quartz, feldspar, and mica. Both are igneous rocks, but basalt is dark-colored and dense, while granite is light-colored and less dense.
Are granite and rhyolite similar in a way?
Yes. Rhyolite and granite have the same composition. Rhyolite is the volcanic equivalent of granite.
What rock has the same composition as granite?
Diorite is a rock that has a composition similar to granite, but with a different texture. Both rocks are composed mainly of quartz, feldspar, and mica minerals. Diorite is typically darker in color and has a coarser grain size compared to granite.
What minerals does the rock granite always contain?
granite has its composition _ quartz+alkali feldspar
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.
Do diorite and rhyolite have the same chemical composition?
No. Diorite has the same composition as andesite while Rhyolite has the same composition as granite.
What continental crust has the average composition of?
Granite. Most of the crust is composed of granite. Feldspar is the most common mineral in the earth's crust.Silicon, (Si) and Alluminium, (Al).
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.
What is the difference between red granite and granite?
Red granite refers to a type of granite that has a predominantly red color, while granite is a general term for a type of igneous rock that is primarily composed of quartz and feldspar minerals.
