Preliminary report on the Comet area, Jefferson County, Montana
George Earle Becraft
1953, Circular 277
Several radioactivity anomalies and a few specimens of sooty pitchblende and other uranium minerals have been found on the mine dumps of formerly productive base- and precious-metal mines along the Comet-Gray Eagle shear zone in the Comet area in southwestern Montana. The shear zone is from 50 to 200 feet...
Uranium occurrences in the Golden Gate Canyon and Ralston Creek areas, Jefferson County, Colorado
John Wagstaff Adams, A. J. Gude III, E.P. Beroni
1953, Circular 320
Pitchblende, associated with base-metal sulfides, has been found at nine localities in the northern part of Jefferson County, Colo., in shear zones that cut pre-Cambrian metamorphic and igneous rocks, chiefly hornblende gneiss, biotite schist, and granite pegmatite. The known deposits are in the vicinity of Halston Creek and Golden Gate...
Niobium (columbium) and titanium at Magnet Cove and Potash Sulphur Springs, Arkansas
Verne Charles Fryklund Jr., R. S. Harner, E.P. Kaiser
1953, Open-File Report 53-74
This work was done because niobium (columbium) has been found in several of the minerals and rocks of the Magnet Cove and Potash Sulphur Springs areas. Niobium is in demand for use in high-temperature and non-creep steels.The Magnet Cove and Potash Sulphur Springs areas are in central Arkansas between Malvern...
Pre-Cambrian geology of the Norway Lake area, Dickinson County, Michigan
Lorin Delbert Clark
1953, Open-File Report 53-37
The Norway Lake area straddles the south margin of the Sagola basin, an embayment of Ruronian sedimentary rocks into the west side of a complex of crystalline and sedimentary rocks of pre-Ruronian age. The north part of the Norway Lake area is underlain by the Randville dolomite, an unnamed succession...
The hydraulic geometry of stream channels and some physiographic implications
Luna Bergere Leopold, Thomas Maddock Jr.
1953, Professional Paper 252
Some hydraulic characteristics of stream channels - depth, width, velocity, and suspended load - are measured quantitatively and vary with discharge as simple power functions at a given river cross section. Similar variations in relation to discharge exist among the cross sections along the length of a river under the...
