Uranium vein mineralization. Tyndrum, Scotland |
Major Minerals: |
Uraninite |
Minor Minerals: |
Chalcopyrite, pyrite, marcasite, galena, safflorite |
Trace Minerals: |
Tetrahedrite, bornite, argentian chalcocite, argentite, native copper, native silver, haematite |
Textures: |
Uraninite, as the variety pitchblende, is collomorphic and shows reflectance variations between bands. it is intergrown with calcite that carries numerous fine-grained haematite inclusions. Uraninite is replaced by galena and chalcopyrite, and smaller crystals are replaced by secondary uranium minerals |
