Strontiohurlbutite
Strontiohurlbutite is an IMA-recognized mineral species in the phosphate class, with the chemical formula SrBe₂(PO₄)₂.
It crystallizes in the monoclinic crystal system (space group P2_1/a). It is a member of the Danburite structural group.
Key properties: Mohs hardness 6; specific gravity 3.101; Vitreous luster; optically biaxial.
IMA symbol Shrb, IMA status: approved, named in 2012.
Found in a highly-evolved zoned pegmatite, likely from reactions between late hydrothermal fluids and primary beryl.
It is found associated with Quartz, muscovite, beryl, hurlbutite, hydroxylherderite, apatite-group minerals, phenakite.
As a strontium-dominant analog of hurlbutite.
