They have been mined in southeastern Idaho, northern Utah, western Wyoming, and southwestern Montana. Low concentrations of uranium are present in the phosphorite beds, and a vanadium-enriched zone is present in western Wyoming and southeastern Idaho. Many of the Phosphoria shales are rich in organic matter and are petroleum source rocks, and petroleum has been produced from some of the dolostones in the formation."@en }
