North Dakota’s Uranium Deposits
![Page 5: Uranium Deposits](https://reader033.vdocument.in/reader033/viewer/2022061617/56816631550346895dd99aae/html5/thumbnails/5.jpg)
Sedimentary Host Rocks
• Sandstones and Arkoses– Porous– Permeable– Lower pH than incoming water
• Coal and lignite beds– Also have low pH compared to inflowing water

Sedimentary-hosted Uranium Deposits
• Very high tonnage but lower grade (compared to unconformity type)
• U transported by ground water
• U deposited as water encounters a reducing environment (organic matter or gas, sulfide minerals)
• Drop in pH results in precipitation of U minerals in pore spaces.

Prerequisites for a Sedimentary-hosted Uranium deposit
1) Source of U2) Coarse sands with good porosity and
permeability3) Ground water flow (naturally oxygenated) –
ideally channelized, high rate of flow4) Reduction zone – heavy minerals, decaying
organic matter
