What is a well-known igneous rock that contains quartz, feldspar, and mica?

Unless you are a scientist or geologist, you may have trouble identifying different kinds of rocks. Some of the igneous rocks include quartz, feldspar and mica. If you have ever replaced your countertop in your kitchen or bathroom, you may be more familiar with types of rocks like quartz and granite because these types of rocks make these high-end countertops.

Igneous rocks can be found all over the world. These rocks are also known as magmatic rocks because they were formed after lava or magma flowed and hardened following a volcanic eruption. As long as there are volcanic eruptions and magma spews forth, people will have access to quartz and granite. Granite is probably the most well-known igneous rock that contains quartz, feldspar and mica.
