Coffinite from the Pandora Mine in Utah, USA. One unique flat.
Coffinite from the famous Pandora Mine in Utah, USA. This unique flat contains a diverse collection of specimens from a classic uranium-vanadium deposit of the American Colorado Plateau. The specimens display a variety of rock types, ore-bearing structures and mineral associations characteristic of this historically important mining district. The predominantly grey to brown specimens provide an excellent illustration of the geological processes responsible for the formation of uranium and vanadium mineralisation.
The Picture shows the exact collection offered. With its variety of sizes, textures and ore-bearing material, the collection offers an interesting overview of specimens from the Pandora Mine and is well suited for collectors of American mineral localities as well as uranium and vanadium minerals.
Geology & Origin
The Pandora Mine in Utah is one of the well-known uranium and vanadium deposits of the Colorado Plateau. The mineralisation formed within sedimentary rocks where uranium- and vanadium-bearing solutions became concentrated over long geological periods. The deposit produced numerous rare mineral species and remains important from both a mineralogical and mining-historical perspective. Among collectors of American ore minerals, the Pandora Mine is regarded as one of the classic localities of North America.
