Kalinite is a fibrous monoclinic type of alum distinct from isometric potassium alumAmerican Mineralogist (1923) 8:15, named in 1868 for its potassium content. Kalium is the Latin name for potassium (hence its chemical symbol, "K").
A proposal to discredit kalinite as a mineral species has been submitted to the International Mineralogical Association, but it is currently (March 2010) on the list of approved mineralshttp://rruff.info/ima. Many older samples, however, have been found to be potassium alumhttp://www.handbookofmineralogy.org/pdfs/kalinite.pdf.
