MINERALOGY OF URANIUM-BEARING DEPOSITS IN THE BOULDER BATHOLITH, MONTANA. Final Report for July 1, 1952-December 31, 1956

Technical Report ·
OSTI ID:4254780
Certain fissure-filling veins of Tertiary age in the Northern half of the Boulder batholith of Montana were found to contain small commercial concentrations of uranium. Siliceous reef veins were composed chiefiy of microcrystailline quartz with microscopic inclusions of pyrite, galena, sphalerite, tetrahedrite, argentite, and uraninite comprisings few ppercent of the volume. Base metal veins contain megacrystalline quartz, abundant megaseopic sulfides of similar kinds to thuse in the reef deposits, and uraninite associated with later microcrystalline quartz and sulfides. Detailed mineralogical studies were made of representatives of both groups of uraniferous deposits. ( J.E.D.)
