Minerals are distinguished by various chemical and physical properties. Differences in chemical composition and crystal structure distinguish the various species. Within a mineral species there may be variation in physical properties or minor amounts of impurities that are recognized by mineralogists or wider society as a mineral variety.
New minerals approved by the International Mineralogical Association (IMA-CNMNC) are allocated unique symbols consistent with the main listing. New symbols are announced in the newsletters of the IMA-CNMNC. An updated "mineral symbol picker" list [7] is also available for checking on the availability of symbols prior to submission for approval.
Dana's classification [1] [2] is a mineral classification developed by James Dwight Dana. It is based on the chemical composition and structure of minerals. It is mainly used in English-speaking countries, especially in the United States. The mineral classification used by the International Mineralogical Association is the Nickel-Strunz ...
When using the chart, it is important to remember these tips: Isotropic and opaque (metallic) minerals cannot be identified this way. The stage of the microscope should be rotated until maximum colour is found, and therefore, the maximum birefringence. Each mineral, depending on the orientation, may not exhibit the maximum birefringence.

This list includes those recognised minerals beginning with the letter A.The International Mineralogical Association is the international group that recognises new minerals and new mineral names; however, minerals discovered before 1959 did not go through the official naming procedure, although some minerals published previously have been either confirmed or discredited since that date.
