Editing Kainite (section)

== Genesis and occurrence ==

Kainite was discovered in the [[Stassfurt]] salt mines in today's [[Saxony-Anhalt]], [[Germany]] in 1865 by the mine official Schöne and was first described by Carl Friedrich Jacob Zincken.<ref>Zincken, C. (1865): Mittheilung an Prof. H.B. Geinitz vom 18.März 1865 [Über ein neues Mineral, Kainit].- Neues Jahrbuch für Mineralogie, Geologie und Paläontologie, 310.</ref><ref>Zincken, C.

Kainite is a typical secondary mineral that forms through metamorphosis in marine deposits of [[potassium carbonate]], and is also occasionally formed through resublimation from volcanic vapours. It is often [[paragenesis|accompanied]] by [[anhydrite]], [[carnallite]], [[halite]], and [[kieserite]].

Kainite is only found in comparatively few places,<ref>{{cite web | url = http://www.mindat.org/show.php?id=2132&ld=2#themap | title = Kainite: Localities for Kainite | publisher = Mindat}}</ref> among them in salt mines in central and northern Germany, [[Bad Ischl]] (Austria), on [[Pasquasia]] in [[Sicily]], in [[Whitby]] (UK), and in the Carlsbad Potash District in [[New Mexico]], in volcanic deposits in [[Kamchatka]]<ref>Pekov, Igor V., et al.

It has also been identified in [[Gusev Crater]] on [[Mars]].<ref>Rice, M. S., et al.

It can also be produced from [[Bittern (salt)|bittern]] remaining after removal of table salt from seawater.
