List of Minerals
|
» Acanthite
Acanthite is the most important silver ore next to galena. Actually there is an argument to be made that acanthite could be the most important silver ore.
|
» Actinolite
Actinolite is a relatively common mineral in some metamorphic rocks. It belongs to a series with the minerals tremolite and ferro-actinolite.
|
» Adamite
Adamite is a favorite among collectors of fluorescent minerals because of its consistent bright green fluorescence under short and long UV light.
|
» Aegirine
Aegirine, which is listed in some guides as acmite, forms impressive crystals that have become classics among collectors.
|
» Aeschynite
Aeschynite is one of several Rare Earth Oxides and has two synonyms; "blomstrandine" and "priorite". Aeschynite`s nomenclature is even more complex than this however.
|
» Ajoite
Ajoite is an attractive copper silicate mineral that is named for its type locality in the Ajo District of Pima County, Arizona.
|
» Albite
Albite is a common felspar and is the "pivot" mineral of two different feldspar series. It is most often associated with the plagioclase series where it is an end member of this series.
|
» Allanite
Allanite, also known as "orthite" in Europe, is one of the most common rare earth minerals, which is somewhat of an oxymoron.
|
» Almandine
Almandine is the most common of the garnets and is usually the garnet found in garnet schists (a type of metamorphic rock composed mostly of mica).
|
» Altaite
Altaite is a member of the Galena Group of minerals. Its properties are very similar to galena as it shares basically the same structure.
|
» Aluminum
Native aluminum rarely occurs naturally in its elemental form, even though only oxygen and silicon are more abundant in the earth`s crust.
|
» Alunite
Alunite is also known as alumstone and is a source of the chemical known as alum, KAl(SO4)2 - 12H2O. Some alunite has also been used to recover potassium and aluminum.
|
» Amber
Amber is a beautiful stone that is cut and polished and used as a valuable gemstone. It is very light in weight which allows it to be used in a large jewelry piece without discomfort.
|
» Amblygonite
Amblygonite is a relatively common phosphate mineral.
|
» Amethyst
Amethyst is the purple variety of quartz and is a popular gemstone. If it were not for its widespread availability, amethyst would be very expensive.
