The Sulfates Class - Amethyst Galleries Mineral Gallery

The Sulfates are an important mineral class and include some very interesting and attractive specimens. Although many minerals belong to this class, only barite, gypsum, and anhydrite can be considered common. The basic chemical unit is the (AO4) complex anion with a charge of negative two (-2).The sulfites, selenites and tellurites (notice the spelling) have a basic unit of (AO3)The A can be ...

Sulfate mineral - Wikipedia

The sulfate minerals are a class of minerals that include the sulfate ion (SO 4 2−) within their structure.The sulfate minerals occur commonly in primary evaporite depositional environments, as gangue minerals in hydrothermal veins and as secondary minerals in the oxidizing zone of sulfide mineral deposits. The chromate and manganate minerals have a similar structure and are often …

Nickel–Strunz classification - Wikipedia

Nickel–Strunz classification is a scheme for categorizing minerals based upon their chemical composition, introduced by German mineralogist Karl Hugo Strunz (24 February 1910 – 19 April 2006) in his Mineralogische Tabellen (1941). The 4th and the 5th edition was also edited by Christel Tennyson (1966). It was followed by A.S. Povarennykh with a modified classification (1966 in Russian ...

The Mineral Gallery - Native Elements Class

The Elements (which include over one hundred known minerals) are a diverse class when taken as a whole. Most of this diversity, however, is due to the diversity of the Non-metals Subclass.. The Metals Subclass and related metal alloys contains metals whose properties are rather similar due to the common way in which they crystallize and bond. The greatest difference in the metals is color.

Reading: Classes of Minerals | Geology

Except for the native element class, the chemical basis for classifying minerals is the anion, the negatively charged ion that usually shows up at the end of the chemical formula of the mineral. For example, the sulfides are based on the sufur ion, S 2–. Pyrite, for example, FeS 2, is a sulfide mineral.
