Silicates are minerals that contain silicon atoms bonded to oxygen atoms. The basic building block for all silicate minerals is called a tetrahedron, where one silicon atom is bonded to 4 oxygen atoms (Figure 3.6).Silicate minerals also often contain other elements, such as calcium, iron, and magnesium.ilicates are minerals that contain silicon atoms bonded to oxygen atoms.

Silicates are the most widespread of the minerals. They are made up of oxygen and silicon the number one and number two most abundant elements in the earth's crust.By themselves they make up over 90% of the weight of the earthâs crust. Most rocks are composed mainly of this class of minerals.ilicates are the most widespread of the minerals.
