Granite is a silicate because it contains 70-77% silica (SiO2). Granite is a rock, and silica is mineral containing the chemical elements silicon (Si) and oxygen (O). Si and O chemically combine to form SiO2. Rocks are made up of minerals, which are made up of chemical elements. Because silicon and oxygen are the two most common chemical elements in the Earth's crust, silicate rocks are very common.

Peridotite, a type of ultramafic rock composed largely of the mineral olivine, has the least silica.
The approximate oxygen content of air is around 21%.
The approximate volume of a 100-g sample of granite can be calculated using its density, which typically ranges from 2.63 to 2.75 g/cm³. Assuming an average density of about 2.7 g/cm³, the volume would be calculated as follows: Volume = Mass/Density, which gives Volume ≈ 100 g / 2.7 g/cm³ ≈ 37.04 cm³. Therefore, the approximate volume of a 100-g sample of granite is around 37 cm³.
Quartz is silicon dioxide (SiO2). Granite is a rock containing many minerals and chemical entities; but granite contain also an important percentage of quartz.
A-Type Granitoids are granites of anorogenic origin with high in SiO2 they can contain up to 77% SiO2 they have high alkalies and form on stable craton environment

Examples of igneous rocks include granite, basalt, and obsidian. The chemical formula for granite is roughly SiO2 (silicon dioxide), for basalt it's typically SiO2, Al2O3, FeO, MgO, CaO, and for obsidian it's SiO2 with minor impurities giving it a glassy texture.
The quartz content of granite is varied.
Granite has more silica than basalt in it.
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%.

The density of granite is between 2,65 g/cm3 and 2,75 g/cm3; the melting point is in the range1 215-1 260 oC. Granite is formed from SiO2, AlO3, K2O, Na2O, CaO, etc. Because granite contain uranium and thorium in traces has a natural radioactivity.
Granite is a type of rock composed of different minerals and does not have a chemical symbol. The minerals found in granite, such as quartz, feldspar, and mica, each have their own chemical symbols like SiO2 for quartz and KAlSi3O8 for feldspar.
