kalinite
Kalinite is a mineral composed of hydrated potassium aluminium sulfate (a type of alum). It is a fibrous monoclinic alum, distinct from isometric potassium alum,〔American Mineralogist (1923) 8:15〕 named in 1868. Its name comes from ''kalium'' (derived from Arabic: القَلْيَه al-qalyah “plant ashes”) which is the Latin name for potassium, hence its chemical symbol, "K".
A proposal to remove recognition of kalinite as a mineral species is scheduled to be submitted to the International Mineralogical Association,〔 currently (March 2010), kalinite is still on the list of approved minerals.〔http://rruff.info/ima〕 Many older samples, however, have been found to be potassium alum.〔http://www.handbookofmineralogy.org/pdfs/kalinite.pdf〕
== Environment ==
Kalinite is a rare secondary mineral observed in the oxidized zone of mineral deposits, as efflorescence on alum slates, in caves, and as a volcanic sublimate.〔American Mineralogist (1927) 12:14〕 It is associated with jarosite, KFe3+3(SO4)2(OH)6, and cuprian melanterite (pisanite), (Fe2+,Cu2+)SO4·7H2O, at Quetena, Chile.〔American Mineralogist (1938) 23:721〕
