NonmineralA nonmineral (mineralogy) is a substance found in a natural environment that does not satisfy the definition of a mineral and is not even a mineraloid. Many nonminerals are mined and have industrial or other uses similar to minerals, such as jewelry. Additional recommended knowledge
Mineral definitionTo be classified as a "true" mineral, a substance must be a solid arising from geological processes having a crystal structure. It must also be an inorganic, naturally-occurring, homogeneous substance with a defined chemical composition. Common Nonminerals
Other considerationsSome minerals, such as the well-known Apatite and Mica, are not homogeneous substances, but are a mixture of related minerals, sometimes referred to as a mineral group. See also |
