Markeyite

Verified February 2017   

Ca9(UO2)4(CO3)13·28H2O

The new mineral markeyite was named for the Markey mine in Red Canyon, Utah, USA, where it was first found. Markeyite is among more than 30 new minerals discovered in several uranium mines in Red Canyon. Collectors often employ ultraviolet lights to locate likely spots to collect because many of the secondary uranyl minerals, such as markeyite, are fluorescent. Typically, they use standard collecting tools, such as hammers and chisels, but they usually switch to more gentle tools for the final step because these minerals occur as delicate efflorescences on the mine walls. Cotype material is deposited in the collections of the Natural History Museum, Los Angeles County, 900 Exposition Boulevard, Los Angeles, CA 90007, USA, catalogue numbers 67091 (holotype), 67092, 67093, 67094 and 69095 (cotype), and the Fersman Mineralogical Museum, Russian Academy of Sciences, Moscow, Russia, registration number 4932/1 (cotype).
