Formula:
Ba3(VO4)2
Colour:
Colorless
Lustre:
Vitreous
Specific Gravity:
5.044 (Calculated)
Crystal System:

Name:
Named for the type locality, the Gurim Anticline, Israel.
Well-known as a synthetic phase.

One of the most simple barium minerals. Other barium-bearing vanadates, all with additional metals, are francevillite, gamagarite, nabiasite, tokyoite, and vésigniéite.

Stoichiometry similar to that of copper vanadates mcbirneyite and pseudolyonsite.
