Heinrichite

This page is currently not sponsored. Click here to sponsor this page.
Formula:
Ba(UO2)2(AsO4)2 · 10H2O
System:
Monoclinic
Hardness:
Member of:
Name:
For mineralogist Eberhardt William Heinrich (1918-1991), University of Michigan.
Autunite Group.

Unstable at room temperature and dehydrates fairly rapidly to metaheinrichite (Walenta, 1965) which may be fully transparent. Most of the specimens shown on the photos here are probably metaheinrichite.
