-
Fourmarierite, a lead uranium oxide, from the closed uranium mine at Shinkolobwe, Katanga, Democratic Republic of Congo. This crystal, which is about 1 mm wide, is remarkable because it shows a complete pseudo-hexagonal crystal form (it's actually orthorhombic). The Fourmarierite sits in a nest of other uranium secondary minerals including Becquerelite, Uranophane, and Studtite. [Field of view = 2.5 mm]
-
Sklodowskite, a magnesium uranium silicate, appears as a yellow spray on colorless gypsum. From Naica, Chihuahua, Mexico. [Field of view = 10 mm]
-
Torbernite (copper uranium phosphate - green prisms), Kasolite (lead uranium silicate - yellow blades), Wulfenite (lead molybdate - red-orange prisms), and Malachite (copper carbonate - green sprays). From Musonoi, Katanga, Democratic Republic of Congo. [Field of view = 4 mm]
