Corkite [SEP] named after
Corkite
Corkite is a phosphate mineral in the beudantite subgroup of the alunite group. Corkite is the phosphate analogue of beudantite and with it, a complete solid solution range exists. Corkite will also form a solid solution with kintoreite.
Corkite is named after County Cork, Ireland; the location where the first notable amount was discovered in 1869. Like many of the other minerals in the beudantite group, corkite is a relatively uncommon, secondary mineral that occurs in oxidation zones near hydrothermal base metal deposits. It occurs associated with
history publications and chronicles. In 1874, the geologist Friedrich August Frenzel named a mineral miraquidite after this forest name (it is not clear which; it may be beudantite or corkite). More recently, it has been suggested that it is the "Černý les" ('black forest') of the Chernyakhov culture.
