Can you help make this a better article? What good localities have we missed? Can you supply pictures of better specimens than those we show here? Can you give us more and better information about the specimens from these localities? Can you supply better geological or historical information on these localities?

Below are some preliminary notes I have made about Arsenuranospathite . This entry and thread has been made as a place holder for information that you will hopefully contribute about Arsenuranospathite . It should be in no way be thought of as a claim I have staked out to write about this mineral, and in fact is an invitation for someone to step forward and create the article about this mineral. If you are so inclined and have questions about the format that such an article should have, go the The welcome topic at the top of the Best Minerals forum and read what has been posted there. Also take a look at some of the more mature articles that have already been written like Rhodochrosite, Adamite, Millerite etc. You will need also to pick out other images of Arsenuranospathite that will go into the article.

HAl(UO2)4(AsO4)4·40H2O
“As wedgelike bladed or acicular crystals, to 0.3 mm…”1 The mineral is associated with zeunerite, uranophane, studtite, uranospinite, ianthinite, metakirchheimerite etc.

Germany
Black Forest, Menzenschwand and Wittichen. “It is found in white to pale yellow lathlike or wedge-shaped crystals of orthorhombic habit with perfect…cleavage.”1 Certainly the crystals from this locality do not exceed 0.3 mm as of this date. The mineral is radioactive as are all uranium minerals and with a mineral as heavily hydrated at this one(40 H2O) it is not going to be very stable. If you have any of this mineral you are strongly advised to keep it in a well sealed container and in a cool place.
