Tin, copper, and uranium at Majuba Hill, Nevada
R.H. Thurston, F.M. Chace
1950, Trace Elements Investigations 81-A
Uranium minerals occur with ores of copper, tin, and silver at Majuba Hill, Nevada. During World War I, the Majuba Hill mine produced about 4,000 tons of 12 percent copper ore, and during World War II about 23,000 tons of ore containing 2 to 4 percent copper and enough tin ore to furnish...

Short routine direct method for the fluorimetric determination of uranium in phosphate rocks
F. S. Grimaldi, Norma S. Guttag
1950, Trace Elements Investigations 134
A short routine direct fluorimetric procedure for the determination of up to 0.06 percent uranium in phosphate ricks is described. The procedure employs a simple acid leach for preparing the solution, and the uranium is determined directly on a 1.8-mg aliquot. The results obtained by using this simply procedure on...

Trace elements reconnaissance in the Jakolof Bay area, southern Alaska
Robert M. Moxham, Arthur E. Nelson
1950, Trace Elements Investigations 74-A
As a result of inquiries by prospectors in 1948 concerning radioactive ores in the vicinity of Jakolof Bay on the Kenai Peninsula in southern Alaska, the Geological Survey conducted a brief investigation during 1949. No radioactive material was found. Possibly a chromite stockpile in this locality was mistaken for pitchblende....

1950, Trace Elements Investigations 61
A reconnaissance for sources of radioactive material in North Dakota and eastern Montana was made in 1948. This reconnaissance was followed by a more detailed survey of parts of Golden Valley and Slope counties, southwestern North Dakota, in June 1949. The radioactivity of representative sections of all formations known to be...
