Uroxite Yellow green crystals of uroxite with steeply sloping terminations and rectangular cross section. Uroxite is the first reported uranyl oxalate mineral, where the source of oxalate likely originates from metabolism or decay of organic matter. Collected by myself and Tim Rose, 2018. Horizontal field of view is 1.7 mm; Locality: Burro Mine, Slick Rock District, San Miguel Co., Colorado, USA; Fov: 1.7 mm; Copyright: Travis Olds; Beitrag: Stefan Fundort: USA/Colorado/San Miguel Co./Slick Rock District/Burro Mine Mineral: Uroxit Bild: 1554366228 Lizenz: Nur zur Mineralienatlas-Projekt-Verwendung |

Paddlewheelite A tabular green crystal of paddlewheelite in a vug of dolomite and chalcopyrite. Collected by myself and Jakub Plá?il Sep 2016, shortly after the 500th anniversary of Jáchymov; The name was chosen to reflect its unique structure that contains fourling paddlewheel units built from uranyl tricarbonate clusters (see child photos). The paddlewheels have square pyramidal copper "axles," with a cubic calcium cation "gearbox."; Locality: Svornost Mine, Jáchymov, Jáchymov District, Karlovy Vary Region, Czech Republic; Fov: 1.7 mm; Copyright: Travis Olds; Beitrag: Stefan Fundort: Tschechien/Karlsbad (Karlovarský kraj)/Karlsbad (Okres Karlovy Vary)/St. Joachimsthal (Jáchymov)/Einigkeit (Svornost) Mineral: Paddlewheelit Bild: 1532383195 Wertung: 10 (Stimmen: 1) Lizenz: Nur zur Mineralienatlas-Projekt-Verwendung |

Shinkolobweite, Fourmarierite, Rutherfordine Dark reddish brown blades of shinkolobweite (IMA 2016-095) coating massive uraninite with orange fourmarierite and pale rutherfordine. Horizontal field of view is 1 mm. The structure of shinkolobweite is modulated and contains pentavalent uranium which produces the deep color. The new mineral originates from a collection of some of the best Shinkolobwe mine specimens at the Canadian Museum of Nature in Ottawa which belonged to the late Bill Pinch; Locality: Shinkolobwe Mine, Shinkolobwe, Katanga Copper Crescent, Katanga, Democratic Republic of Congo; Fov: 1 mm; Copyright: Travis Olds; Beitrag: Stefan Fundort: Demokratische Republik Kongo/Katanga (Shaba), Provinz/Ober-Katanga (Haut-Katanga), Distrikt/Shinkolobwe (Kasolo)/Shinkolobwe Mine (Kasolo Mine) Mineral: Shinkolobweit Bild: 1493731555 Lizenz: Nur zur Mineralienatlas-Projekt-Verwendung |

Uranophane An aesthetic vug of acicular uranophane crystals to 1 mm in amphibole gneiss from one of the most radioactive uranium prospects in Upper Michigan -- which is actually an exposure only ~2 feet long! Uranyl silicates like uranophane, sklodowskite, and kasolite are the dominant secondary U minerals but some incredibly unique phases are formed by alteration of molybdenite and leached radiogenic Pb. Vugs such as this one are incredibly rare as the U-silicates typically occur as ugly massive "gummite" coatings. EDS and Raman spectroscopy confirmed. Collected 2011.
