Mineral

adj. of or pertaining to minerals, consisting of minerals

n. natural substance belonging to a group of inorganic (often crystalline) compounds which are found in the earth, that which is not animal or vegetable

A mineral is a naturally occurring substance formed through geological processes that has a characteristic chemical composition, a highly ordered atomic structure and specific physical properties. A rock, by comparison, is an aggregate of minerals and need not have a specific chemical composition. Minerals range in composition from pure elements and simple salts to very complex silicates with thousands of known forms. The study of minerals is called mineralogy.
