mineral | Types & Uses | Britannica

Since a mineral has a definite composition, it can be expressed by a specific chemical formula.Quartz (silicon dioxide), for instance, is rendered as SiO 2, because the elements silicon (Si) and oxygen (O) are its only constituents and they invariably appear in a 1:2 ratio. The chemical makeup of most minerals is not as well defined as that of quartz, which is a pure substance.

Physical Properties of Minerals - Tulane University

Magnetic minerals result from properties that are specific to a number of elements. Minerals that do not have these elements, and thus have no magnetism are called diamagnetic. Examples of diamagnetic minerals are quartz, plagioclase, calcite, and apatite.

Mineral - Wikipedia

High specific gravity is a diagnostic property of a mineral. A variation in chemistry (and consequently, mineral class) correlates to a change in specific gravity. Among more common minerals, oxides and sulfides tend to have a higher specific gravity as they include elements with higher atomic mass.
