'''Lulzacite''' is a [strontium](/source/strontium)-containing [phosphate mineral](/source/phosphate_mineral) with the chemical formula Sr<sub>2</sub>Fe<sup>2+</sup>(Fe<sup>2+</sup>,Mg)<sub>2</sub>Al<sub>4</sub>(PO<sub>4</sub>)<sub>4</sub>(OH)<sub>10</sub>.<ref name=webmin>{{cite web|url=https://webmineral.com/data/Lulzacite.shtml|title=Lulzacite Mineral Data|work=webmineral.com|publisher=David Barthelmy|accessdate=September 4, 2010}}</ref><ref name=mindat>{{cite web|url=http://www.mindat.org/min-7058.html|title=Lulzacite|work=mindat.org|publisher=Jolyon Ralph and Ida Chau|accessdate=September 4, 2010}}</ref>

The mineral was first described in 2000 from [quartzite](/source/quartzite) deposits ({{coord|47|42|50|N|1|29|20|W}}) at [Saint-Aubin-des-Châteaux](/source/Saint-Aubin-des-Ch%C3%A2teaux), Loire-Atlantique, France, and is named after [Y. Lulzac](/source/Y._Lulzac), a French geologist who discovered the mineral. In this deposit, lulzacite occurs within [quartz](/source/quartz) and [siderite](/source/siderite) veinlets at quartzite–[limestone](/source/limestone) contacts. Other minerals found in the veinlets include [apatite](/source/apatite), [goyazite](/source/goyazite), and [pyrite](/source/pyrite).<ref name=moelo00>{{cite journal|title=Lulzacite, Sr<sub>2</sub>Fe<sup>2+</sup>(Fe<sup>2+</sup>,Mg)<sub>2</sub>Al<sub>4</sub>(PO<sub>4</sub>)<sub>4</sub>(OH)<sub>10</sub>, a new strontium phosphate (Saint-Aubin-des-Châteaux, Loire-Atlantique, France). |first1=Yves |last1=Moëlo |authorlink1=Yves Moëlo |author2=Bernard Lasnier |author3=Pierre Palvadeau |author4=Philippe Léone |author5=François Fontan |journal=Comptes Rendus de l'Académie des Sciences, Série IIA |date=15 March 2000|volume=330|issue=5 |pages=317&ndash;324|doi=10.1016/S1251-8050(00)00152-X|bibcode = 2000CRASE.330..317M }}</ref>

Lulzacite crystallizes in the [triclinic system](/source/Triclinic_crystal_system) with P{{overline|1}} space group. It is isostructural with [jamesite](/source/jamesite) (Pb<sub>2</sub>Zn(Fe<sup>2+</sup>,Zn)<sub>2</sub>Fe<sup>3+</sup><sub>4</sub>(AsO<sub>4</sub>)<sub>4</sub>(OH)<sub>10</sub>).<ref name=moelo00/><ref>{{cite web|url=http://www.mindat.org/min-2071.html|title=Jamesite|work=mindat.org|publisher=Jolyon Ralph and Ida Chau|accessdate=September 4, 2010}}</ref>
