Although similar to rocks, minerals are the building blocks for making rocks, and are found in various types of rock in differing shapes and chemical compositions throughout the Earth's crust. Although minerals differ in shape, composition and distribution, four major classes of minerals make up the Earthâs crust. Silicates The silicate class of minerals makes up 90 percent of the Earthâs crust, and is compounds of silicon and other chemical elements. The two most common silicate types found in the Earthâs crust are quartz and feldspar minerals.
