Natromarkeyite
Bladed yellow-green natromarkeyite from the Markey mine. Its structure is related to markeyite, where 2 Na replace 1 Ca and 1 H2O group; Locality: Markey Mine, Red Canyon, White Canyon Mining District, San Juan Co., Utah, USA; Fov: 1.3 mm;

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;

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;

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;

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. Locality: Paulding Uranium prospect, Watersmeet, Gogebic Co., Michigan, USA;

Sklodowskite, Uranophane, Molybdenite
A pale green field of massive to radiating sklodowskite and uranophane coating molybdenite and uraninite. At SEM level magnification the field turns into a web of thousands of thin fibrous crystals. EDS and Raman spectroscopy confirmed; Canon T3i w/ mirror lock engaged; EFS-60 and 49mm tube; FOV: 0.6 cm; Diffused dual fiber lighting; CombineZP: 12 images, pyramid do stack; Locality: Paulding Uranium prospect, Watersmeet, Gogebic Co., Michigan, USA;
