Natrojarosite from
Wanthwaite Mine, St. John's Castlerigg and Wythburn, Allerdale, Cumbria, England, UK

Locality type:Mine
Comments:Kingsbury reference. Kingsbury and Hartley (1958): "While the southernmost vein at the Wanthwaite mine yielded jarosite, the northern vein yielded its rarer relative, natrojarosite (NaFe3(SO4)2(OH)6).[...] aggregates of small (up to 0.5 mm.) golden-brown rhombohedral crystals on massive and botryoidal goethite, the crystals showing combinations of the basal plane c{0001} with e{1011} and s{0112}."
