Minerals Minerals are The natural way developing, commonly crystalline, chemical compounds. Minerals vary from rocks and fossils because of their individual and specific chemical compositions (as opposed to currently being a mix of many, as rocks are) and their exclusion from being manufactured from lifestyle processes.
