- Alunite - Wikipedia
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 was mined for the manufacture of alum First called aluminilite by J C Delamétherie in 1797, this name was contracted by François Beudant three decades later to alunite [8

Sato, Eriko, Nakai, Izumi, Miyawaki, Ritsuro, Matsubara, Satoshi (2009) Crystal structures of alunite family minerals: beaverite, corkite, alunite, natroalunite, jarosite, svanbergite, and woodhouseite
- Alunite | Mineral, Description, Uses, Facts | Britannica
Alunite, a widespread rock-forming sulfate mineral that occupies pockets or seams in volcanic rocks such as rhyolites, trachytes, and andesites, where it presumably formed through their chemical reaction with escaping sulfurous vapors
- Alunite Mineral Data
Alunite Comments: Octahedral clear to tan tinted crystals of alunite Location: Marysvale, Piute County, Utah, USA Scale: See Photo © Jeff Weissman Photographic Guide to Mineral Species
- Alunite Mineral Information photos and Facts - Nevada Outback Gems
Alunite is often found disseminated in the rocks or in well-defined veins Notable occurrences in the western USA are at Goldfield, Nevada; Marysvale, Utah; and the Rosita Hills, Colorado The alunite near Marysvale in Utah occurs in veins traversing andesites that are probably of Tertiary age
- Alunite KAl3(SO4 2(OH)6 - Handbook of Mineralogy
Mineral Group: Alunite group Occurrence: Formed between 15 C and 400 C by the action of sulfate, which may be generated from pyrite or solfataric action, on aluminous rocks, commonly accompanied by kaolinitization and silicification Association: Kaolinite, halloysite, diaspore, pyrite, gypsum, quartz
- Alunite - Occurrence, Properties, and Distribution - AZoMining
Alunite is a sulfate mineral first discovered in Monti della Tolfa, Rome in the 15 th century It is rarely found in the massive material cavities as distinct crystals It occurs as veins and replacement masses in rhyolite, trachyte and other potassium rich volcanic rocks
- ALUNITE (Potassium Aluminum Sulfate Hydroxide)
Alunite forms from the action of sulfuric acids upon potassium rich feldspars in a process called "alunitization" The sulfuric acids accompany hydrothermal solutions, usually rich in certain ore metals These solutions can result in large bodies of alunite, making alunite a rock forming mineral
