Quaternary geology of the Nenana River and adjacent parts of the Alaska Range, Alaska
Clyde Wahrhaftig
1953, Open-File Report 53-262
The Nenana River flows northward across the Alaska Range near 149° west longitude. Sedimentary bedrock formations of its basin include pre-Cambrian schist undifferentiated Paleozoic and Mesozoic rocks, continental upper Cretaceous rocks and poorly consolidated continental Tertiary rocks. Igneous rocks include pre Devonian quartz orthoclase schist, greenstone, granitic and basic intrusives...
Measurement of earth pressure in the iron-ore mines of eastern France
M.E. Tincelin
1953, Open-File Report 54-30
The purpose of the tests, which will be reported later, is to measure as precisely as possible the tangential stresses exerted on the periphery of a gallery cut in the Lorraine iron ore. The values of the tangential stresses along the periphery being known, they will be compared with the values...
Geology and coal deposits of Jarvis Creek coalfield, Alaska
Clyde Wahrhaftig, C.A. Hickcox
1953, Open-File Report 53-263
The Jarvis Creek coal field lies on the north side of the Alaska Range between latitudes 63°35' and 63°45 N., and longitudes 145°40' and 145°50 W. It is 2 to 6 miles east of the Richardson Highway. The coal field is about 16 square miles in area, the major part...
Water, frost, and frost resistance of natural and artificial building stones
H. Breyer, S. H. Britt (translator)
1953, Open-File Report 54-33
The worst enemy of construction engineering and of construction material is uncontrollable water, whether it be ground-, seepage-, rainwater, water of condensation, or melting snow and ice, exerting objectionable pressure upon tracks and roads. this applies as well to structures above the ground as to bridge piers and foundations, road...
Geology of the Plumtree area, Spruce Pine district, North Carolina
Donald Albert Brobst
1953, Open-File Report 53-26
This report describes the results of study and geologic mapping (1:12,000) in the 70-square-mile Plumtree area in the northeastern part of the Spruce Pine pegmatite district, on the Blue Ridge upland in western North Carolina. The district has been the chief domestic source of feldspar and sheet mica. The mining...
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...
Measurement of earth pressures by means of the flat jack test
P. Habib, R. Marchand, Severine Britt (translator)
1953, Open-File Report 54-31
This study deals with the principle and application of a method of measuring the stresses around a rock gallery. The measuring principle consists of cutting a drain in a gallery wall, observing the corresponding stress lessening, then restoring the initial state of stress by means of a Freyssinet flat jack. The...
Preliminary report on the Little Susitna district, Matanuska coal field, Alaska
Farrell F. Barnes
1953, Open-File Report 53-10
The Little Susitna district, as defined in this report, occupies an area roughly 25 miles long and 3 miles wide on the north side of the lower (western) extremity of the Matanuska Valley in south-central Alaska (fig. 1). The district is bounded on the north by the Talkeetna Mountains, on...
Stratigraphic sections of the Phosphoria formation measured and sampled in 1952
Thomas McGiffin Cheney, R.P. Sheldon, E. R. Cressman, R.A. Smart, L.D. Carswell
1953, Open-File Report 53-36
A series of reports presenting detailed stratigraphic sections and analyses of samples of the Phosphoria formation in the western phosphate field is being prepared for publication as U. S. Geological Survey Circulars. To speed the availability of these data to industry and others having immediate need for such basic information,...
Floods of 1950 in the upper Mississippi River and Lake Superior basins in Minnesota
C. G. Paulsen
1953, Water Supply Paper 1137-G
In areal coverage and magnitude of peak discharge the floods of April-May 1950 in the Missouri River Basin in North and South Dakota were unprecedented in the area. These floods were characterized by an extremely late spring breakup of ice, by great flood peaks resulting from snow melt, and by...
