Granite mineralogy varies widely, but in general granites contain both plagioclase and alkali feldspars along with quartz. Other minerals which may also be present are muscovite and biotite micas, pyroxene, amphiboles, tourmaline, sphene, apatite, augite, zircons, beryl, topaz, garnet, cordierite, fayalite, titanite, and possibly rare earth oxides.

∙ 11y agoThe textbook definition of a "true" granite requires an almost equal mix (~ 30% of each by volume) of potassium feldspar, plagioclase feldspar, and quartz. There are many variations of this, though, (ex: 60% k-spar, 10% plagioclase, 30% quartz), or any combination of those, which fall under the category of "granitoids". The abundance of each mineral is determined and plotted on a triangular plot known as the QAP Diagram (Quartz-Alkali feldspar-Plagioclase feldspar). Granite falls right in the middle (meaning, near equal proportions of each).

What minerals are in granite but not gabbro?
Granite contains Quartz and Plagioclase Feldspar and Gabbro does not have neither if these minerals in it.
What rocks such as granite occur as a solid mixture?
The solid mixture that granite is made of consists of three materials. This mixture is usually made of feldspar, mica, and quartz.
What minerals determine the color of granite?
The color and type of feldspar minerals largely determine the color of a particular granite.
What does granite contains?
Granite contains several types of minerals. They include quartz, calcite, micas, and tourmaline. Granite can also have trolite and silicate minerals.
Is granite homogeneous?
No. If you look at granite you can see that there are distinct crystals of diferent minerals. Thus, granite is heterogeneous.
What minerals make up the outer core?
nickel and granite nickel and granite
What does granite form from?
In the volcano/magma chamber, different minerals that make up granite, (feldspar, quartz, etc.) mix to form grainy, large crystals of the different minerals. That is how granite is formed.
What types of rock make up Granite?
Mainly Quartz, Feldspar, and Hornblende. Often there is Mica (usually biotite or muscovite). By the way, these are minerals, not rocks that make up granite. Granite IS the rock.
What type of minerals make up most of Earth's crust?
Basalt and Granite.
What is lighter gabbro or granite?
Granite is lighter because its composed of felsic minerals while gabbro is made up of dark ferromagnesian minerals.
Does granite have a definite chemical makeup?
No. Minerals have definite chemical structures, but not rocks.
Is granite a homo or heterogeneous mixture?
A granite countertop is a heterogeneous mixture. Granite, the main material in a granite countertop, is a type of metamorphic rock that contains minerals such as quartz and feldspar. Quartz and feldspar are two different types of minerals which make up granite. Therefore, because there are two different types of minerals in one substance it makes it heterogeneous.
What rock is made up of the same minerals as granite?
Rhyolite.
Why can minerals be found in rocks but rocks cannot be found in minerals?
Because rocks are made up of minerals but minerals aren't made up of rocks. Rocks are made up of little bits of many minerals. An example is granite. You know how it has speckles in it? Those are a bunch of mineral grains mixed up to form the rock granite.
Do minerals make up the rock quartz?
Quartz itself is the mineral. Its formula is SiO2. Rocks are aggregates of minerals, so an example of a rock that contains a lot of quartz is granite.
What are the main types of minerals that make up the continental and oceanic plates?
c plates- bedrock and granite o plates- bastlic
Granite is made up of the minerals feldspar and mica?
granite is made up of the minerls feldspar and mica
