WebUraninite occurs as a primary mineral in granitic and syenitic pegmatites. Well-formed crystals are rare but cubes, octahedrons and modified … Uraninite, formerly pitchblende, is a radioactive, uranium-rich mineral and ore with a chemical composition that is largely UO2 but because of oxidation typically contains variable proportions of U3O8. Radioactive decay of the uranium causes the mineral to contain oxides of lead and trace amounts of helium. It may also contain thorium and rare-earth elements.
