Becquerelite, Studtite and Uranophane on Uraninite
Shinkolobwe, Katanga, Democratic Republic of the Congo
7 x 5 x 2.1 cm
Fabulous specimen of this rare calcium uranium hydroxide. Literally hundreds of blade-like crystals of becquerelite to 4 mm are found across the surface of this specimen. Also present are tufts of studtite - a hydrous uranium oxide. This is one of those specimens that I could have taken a hundred pictures of - so many interesting nooks on this specimen!
