Rocks are made up of minerals. A mineral is naturally occurring and inorganic, and has a distinct chemical formula and crystal structure. When minerals form in open spaces, their crystal form is apparent (Fig. 1A). However, most minerals occur in an interlocking network with other minerals to form different kinds of rocks (Fig. 1B).
