Alunite is sometimes associated with valuable gold deposits. In volcanic regions it is not uncommon to find considerable areas of bleached and altered lavas which contain more or less alunite K20.3A12O3.4S03.6H2O, an earthy or compact, rarely coarsely crystalline mineral of inconspicuous appearance.

Also known as Alunite Family or Alunite Group. This supergroup includes Alunite Group, Beudantite Group, Plumbogummite Group and Dussertite Group. Various other names have been used for these groups see Mills et al. 2009 Bayliss et al. 2010. Crystals in the group are generally small, imperfect, and rare.

Alunite is a hydroxylated aluminium potassium sulfate mineral, formula K Al 3 S O 4 2 OH 6. It was first observed in the 15th century at Tolfa, near Rome, where it is mined for the manufacture of alum. First called aluminilite by J.C. Delamtherie in 1797, this name was contracted by Franois Beudant three decades later to alunite.
