Mineralogy is an active science in which minerals are discovered or recognised on a regular basis. Use of old mineral names is also discontinued, for example when a name is no longer considered valid. Therefore, a list of recognised mineral species is never complete. Minerals are distinguished by various chemical and physical properties ...
Mineral species belonging to the wolframite group contain small cations such as magnesium, manganese, iron, cobalt, and nickel. The tungstates huebnerite ( MnWO 4 ) and ferberite ( FeWO 4 ) are considered to be end members of a series of solid solution in which manganese may substitute for various quantities of iron and vice versa.

Minerals are substances that are formed naturally in the Earth. They are the building blocks of rocks. Minerals are usually solid, inorganic, have a crystal structure, and form naturally by geological processes.[1] The study of minerals is called mineralogy.[2] A mineral can be made of single chemical element or more usually a compound. There ...
A mineral is, broadly speaking, a solid chemical compound that occurs naturally in pure form. [1] Minerals are most commonly associated with rocks due to the presence of minerals within rocks. [2] These rocks may consist of one type of mineral, or may be an aggregate of two or more different types of minerals, spacially segregated into distinct …
