Conference GEOCHEMISTRY AND MINERALOGY OF THE LEMHI PASS REE-Th DEPOSITS: AN EXAMPLE OF REE-TH MOBILITY. P. E...The Lemhi Pass REE-Th deposits sits astride the continental divide partially in Beaverhead County, Montana...Montana and, partially in Lemhi County, Idaho. Mineralization occurs in veins with potassic alteration...activity.
