In geology, a rock (or stone) is a naturally occurring solid aggregate of one or more minerals or mineraloids. For example, the common rock granite is a combination of the quartz, feldspar and biotite minerals. The Earth's outer solid layer, the lithosphere, is made of rock. Rocks have been used by mankind throughout history. From the Stone Age rocks have been used for tools.

In an industrial context, "stone" refers to rocks, minerals, and other naturally occurring materials that can be quarried, processed, and used for various purposes.
