KGS Home > Rocks and Minerals

The basic building blocks of all rocks, minerals, liquids, and gases are chemical elements, which are made up of various combinations of atoms. For example, when lead atoms combine with sulfur atoms, the mineral galena is formed. There are many definitions of the word "mineral." In earth science, a mineral is a naturally occurring solid with a definite chemical composition and crystal structure. Rocks are naturally occurring solids composed of one or more minerals. Unless otherwise noted, minerals mentioned here occur in Kentucky.
