Formula:
SrBe2(PO4)2
Colour:
light blue
Lustre:
Vitreous
Hardness:
6
Specific Gravity:
3.101 (Calculated)
Crystal System:
Monoclinic
Name:
Named in 2012 by C. Rao, R. Wang, X. Gu, H. Hu, and C. Dong for being the Sr analogue of hurlbutite.
Isostructural with:
Sr-dominant analogue of hurlbutite. Compare minjiangite which is not a true (structural-chemical) but just chemical (Ba) analogue.
The structure has paracelsian topology; as such, the species may alternatively be grouped within "paracelsian group", alongside with danburite, pekovite, maleevite, paracelsian, and hurlbutite.
