Stratigraphy and structure of the Miners Mountain area, Wayne County, Utah
Robert G. Luedke
1953, Open-File Report 53-161
The Miners Mountain area includes about 85 square miles in Wayne County, south-central Utah. The area is semiarid and characterized by cliffs and deep canyons. Formations range in age from Permian to Upper Jurassic and have an aggregate thickness of about 3,500 feet. Permian formations are the buff Coconino sandstone and...
Reconnaissance geology of placer deposits containing radioactive minerals in the Bear Valley district, Valley County, Idaho
J. Hoover Mackin, Dwight Lyman Schmidt
1953, Open-File Report 53-167
A reconnaissance of the Bear Valley district was undertaken to provide a geologic interpretation of placer deposits drilled by the U.S. Bureau of Mines. The placer minerals are monazite and a group of uranium bearing rare earth columbates and tantalates here referred to loosely as radioactive blacks. The monazite is...
Observation of a "front" of regional metamorphism
Rene Perrin, Marcel Roubault, S. H. Britt (translator)
1953, Open-File Report 54-32
Drawing his inspiration from the theories on metamorphism by reaction in the solid state, and from some observations, Rene Perrin in his article 'Perrin, Rene, Le metamorphisms generateur de plissement, Annales des Hines, Paris, October 1935.' "Metamorphism, the generator of folding" stated in 1935: 1) that some "sudden arrest" of regional...
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...
