'''Fourmarierite''' is a secondary uranium-lead mineral. It was named for the Belgian geologist Paul Fourmarier (1877–1970). Its chemical formula is {{chem|Pb|(U|O|2|)|4|O|3|(OH)|4|•4H|2|O|}}.<ref>{{cite web |url=http://webmineral.com/data/Fourmarierite.shtml |title=Fourmarierite Mineral Data |publisher=webmineral.com |accessdate= 15 May 2012}}</ref>
