What is a mineral?

A mineral is a naturally occurring substance with distinctive chemical and physical properties, composition and atomic structure.

To be more specific, James D. Dana (1813-1895) developed the first widely used mineral classification system and defined a mineral as 'a naturally occurring solid chemical substance formed through biogeochemical processes, having characteristic chemical composition, highly ordered atomic structure, and specific physical properties.'

There is debate whether minerals can be wholly or partly anthropogenic, whether minerals may have biological origins, and whether some mineral-like, non-crystalline materials can be considered as candidates of the recognised mineralogical pantheon.
