What is "lulzacite"

n. (context mineralogy English) A triclinic-pinacoidal mineral containing aluminum, hydrogen, iron, magnesium, oxygen, phosphorus, and strontium.

Lulzacite is a strontium-containing phosphate mineral with the chemical formula SrFe(Fe,Mg)Al(PO)(OH).

The mineral was first described in 2000 from quartzite deposits 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.

Lulzacite crystallizes in the triclinic system with P space group. It is isostructural with jamesite (PbZn(Fe,Zn)Fe(AsO)(OH)).
