Lulzacite
Lulzacite is a strontium-containing phosphate mineral with the chemical formula Sr2Fe(Fe,Mg)2Al4(PO4)4(OH)10.
The mineral was first described in 2000 from quartzite deposits (47°42′50″N 1°29′20″W / 47.71389°N 1.48889°W) at Saint-Aubin-des-Châteaux, Loire-Atlantique, France, and is named after Y. Lulzac, a French geologist who discovered the mineral. In this deposit, lulzacite occurs within quartz and siderite veinlets at quartzite–limestone contacts. Other minerals found in the veinlets include apatite, goyazite, and pyrite.
