* Feldspar: A very common mineral group that makes up about 60% of the Earth's crust. It is a silicate mineral containing aluminum and other elements like sodium, potassium, and calcium.
* Clay minerals: These are a group of layered silicate minerals that contain aluminum, silica, and water. They are common in sedimentary rocks and soils.
* Granite: A common igneous rock composed primarily of feldspar, quartz, and mica. It often contains aluminum silicates.
* Basalt: A common volcanic rock that can contain aluminum silicates, but it is primarily composed of pyroxene and plagioclase feldspar.
* Schist: A metamorphic rock that is often rich in mica and other minerals, including aluminum silicates.
* Gneiss: Another metamorphic rock that can contain aluminum silicates, particularly in the form of feldspar and mica.
It's important to note that the specific minerals present in a rock will vary depending on its origin and formation process.
