Contemporary society relies upon minerals for many of the products that it uses. Mineralogy involves the systematic study of minerals with an emphasis on the common rock-forming minerals. The basic principles of chemistry and symmetry are used to understand mineral properties and crystal structures. Topics include crystallography, crystal chemistry, the origin of mineral color, environmental issues related to minerals, and systematic study of major silicate and non-silicate minerals.
