==Description==

A '''mineral''' is a naturally occurring solid [[chemical]] substance that is formed through [[geological]] [[processes]] and that has a characteristic chemical [[composition]], a highly ordered [[atomic]] [[structure]], and specific physical properties. By [[comparison]], a rock is an aggregate of minerals and/or [http://en.wikipedia.org/wiki/Mineraloid mineraloids] and does not have a specific chemical composition. Minerals range in [[composition]] from [[pure]] [[elements]] and simple [http://en.wikipedia.org/wiki/Salt salts] to very [[complex]] silicates with thousands of known forms. The study of minerals is called [http://en.wikipedia.org/wiki/Mineralogy mineralogy].

To be [[classified]] as a true mineral, a substance must be a [[solid]] and have a [[crystalline]] [[structure]]. It must also be a naturally occurring, [[homogeneous]] substance with a defined chemical composition. [[Traditional]] definitions excluded organically derived [[material]]. However, the [http://en.wikipedia.org/wiki/International_Mineralogical_Association International Mineralogical Association] in 1995 adopted a new definition:
