The difference is in their chemical composition and crystal structure which gives them different properties.
quarts, feldspar and mica
Granite is composed of feldspar, quartz, biotite and muscovite mica. It has a high amount of silica. Granite is an igneous rock.
quartz
In combination with oxygen, silicon appears in large number of molecules. These include metal silicates in rocks such as feldspar and mica, and as silicon dioxide (silica) in sand, quartz, flint, and the gemstones amethyst and opal.

Yes. Mica minerals are silicates.
Silicate minerals are those composed of silicon and oxygen atoms. Some of these minerals are quartz, feldspar, mica and olivine.
Quartz and the Feldspar are very common. Other common silicates would be the mica group, even pyroxenes and the amphiboles.
Both feldspar and mica are silicates.

Mica schist is primarily composed of mica, whereas aventurine - note the spelling- is composed of quartz with abundant inclusions of mica. This makes for a relatively hard, tough and attractive material that can be polished into jewelry and many other items.
