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 Arsenuranylite . This entry and thread has been made as a place holder for information that you will hopefully contribute about Arsenuranylite . 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 Arsenuranylite that will go into the article.
Arsenuranylite. Cherkasar U Deposit, Pap, Namangan Viloyati, Uzbekistan FOV 6mm
*Arsenuranylite Micro? and rare species collections. Ca(UO2)4(AsO4)2(OH)4·6H2O “As fine scales and lichenlike incrustations of elongated crystals, to 0.5 mm.”1 The mineral has also been found in Germany, Black Forest, Menzenschwand. The crystals from either Germany or Uzbekistan so far apparently do not exceed 0.5 mm. 1 Handbook of Mineralogy, Volume IV, Anthony, Bideaux, Bladh, Nichols, p37.
Uzbekistan Chatkal Mountains, Pap, Cherkasar Uranium deposit.1 “The mineral occurs in lichen-like deposits, color more orange than that of phosphuranylite. Under the microscope appears as extremely fine yellow scales. …The mineral occurs in the oxidation zone of a deposit containing arsenic-bearing sulfide (no locality given as usual), associated with metazeunerite, uranospinite, and nováčekite, which it replaces; it is replaced by shoepite and paraschoepite.”2 During the cold war the Russians treated mineral deposits as national secrets, especially uranium mines. Michael Fleischer was the person who abstracted the entry in the American Mineralogist from which this entry was taken, and his comment “as usual” was his way of expressing irritation at the secretive ways of the Russian state. 1 Handbook of Mineralogy, Volume IV, Anthony, Bideaux, Bladh, Nichols, p37; 2 American Mineralogist, Vol. 44, p. 208, 1959.
