3.3: Silicate Minerals

Silicate minerals are built around a molecular ion called the silicon-oxygen tetrahedron. A tetrahedron has a pyramid-like shape with four sides and four corners. Silicate minerals form the largest group of minerals on Earth, comprising the vast majority of the Earth's mantle and crust. Of the nearly 4,000 known minerals on Earth, most are rare.
