A mineral is a naturally occurring substance that is solid and inorganic and has a set chemical formula.  Differences in chemical composition and crystal structure distinguish various species, and are influenced by the mineral's geological environment.  They are described by characteristics such as habid, hardness, lustre, color, streak, clevage, fracture, parting, and specific gravity.  

The subdivisions of this category are based on scietific groups from the discipline of mineralogy.
