About MetauranospiniteHide

Formula:
Ca(UO2)2(AsO4)2 · 8H2O
Colour:
Greenish yellow, yellowish green
Lustre:
Sub-Vitreous, Resinous, Waxy, Pearly, Dull
Hardness:
2 - 3
Specific Gravity:
3.94
Crystal System:
Tetragonal
Name:
Named in 1904 by Paul Gaubert for the dehydration relationship to uranocircite using synthetic material. Earliest natural report is unknown. Metauranospinite does not appear in Frondel (1958) Systematic Mineralogy of Uranium and Thorium. The original spelling was meta-uranospinite; the hyphen was removed in a renaming by the IMA in 2007 (Burke 2008).
Isostructural with:
Meta-autunite, Metatorbernite
Meta-autunite Group.
Dehydration product of uranospinite.
