A mineral is a naturally occurring substance, representable by a chemical formula, that is usually solid and inorganic, and has a crystal structure. It is different from a rock, which can be an aggregate of minerals or non-minerals and does not have a specific chemical composition.
Minerals are naturally occurring chemical compounds that have a solid, crystalline structure, meaning they're arranged in unique geometric patterns at the atomic level. Minerals are also inorganic; they're not formed from amino acids, peptides, or enzymes, as living things are.inerals grouped together form rocks; the combination of minerals determines the type of rock formed. Since minerals are pure, they can all be written as a single chemical formula. A mineral can also contain some impurities and still retain its name, as long as the majority of the solid is a single mineral.
