Geology of the southeastern part of the Robinson Mountains, Yakataga district, Alaska
Don John Miller
1955, Open-File Report 55-114
This report gives the results of geologic investigations in the Yakataga district on the south coast of Alaska, including detailed geologic mapping in the southeastern part of the Robinson Mountains, and reconnaissance study of the stratigraphy and structure of adjoining areas. The geologic map that accompanies this report covers an...
Geology of two areas of pegmatite deposits in southeastern Alaska
C.L. Sainsbury
1955, Open-File Report 55-159
A pegmatite deposit about 600 feet in diameter crops on a high bluff less than one-half mile east of a small unnamed cove between Redfish and Byron Bays, on the west coast of Baranof Island, southeastern Alaska.The deposit which comprises several pegmatite bodies consists of quartz, albite-oligoclase, microcline and mica,...
Fitting curves to cyclic data
W. B. Langbein
1955, Open-File Report 55-91
A common problem in hydrology is to fit a smooth curve to cyclic or periodic data, either to define the most probable values of the data or to test some principle that one wishes to demonstrate.  This study treats of those problems where the length or period of the cycle...
Geochemical exploration for antimony in southeastern Alaska
C.L. Sainsbury
1955, Open-File Report 55-158
Preliminary geochemical prospecting by the Geological Survey was carried out in 1952 in muskeg-covered ground at Caamano Point, Cleveland Peninsula, Alaska, in an effort to delimit areas of stibnite concentrations. It was conducted to aid, if possible, a prospecting project of the Defense Minerals Exploration. Samples were collected from soil...
Uranium in the Gas Hills area, Fremont and Natrona Counties, Wyoming
J. D. Love
1955, Open-File Report 55-98
Uranium minerals have been discovered in the Wind River formation of early Eocene age, strata of middle and late Eocene age, and the Thermopolis shale of early Cretaceous age in the Gas Hills area of central Wyoming.  The localities of uranium mineralization were found independently by prospectors and by geologists...
Photogeologic procedures in geologic interpretation and mapping
Richard G. Ray
1955, Open-File Report 55-144
In the past few years increasing use has been made of aerial photographs for geologic interpretation and mapping within the U.S. Geological Survey. As a specialized technique in interpretation and mapping, however, photogeologic procedures were extensively used (1947-1953) in the Survey's geologic mapping of Naval Petroleum Reserve No. 4 in...
Occurrence of diatomaceous earth near Kenai, Alaska
George Plafker
1955, Open-File Report 55-139
Diatomaceous earth occurs in post-glacial lake deposits exposed along the shore of Cook Inlet north of the village of Kenai, Alaska. Diatomaceous earth is an unconsolidated earthy deposit formed by accumulation of the minute siliceous tests (skeletons) of diatoms, a type of algae. Diatomaceous earth is sometimes referred to...
Geology of the Fourmile pegmatite area, Custer County, South Dakota
Jack Allison Redden
1955, Open-File Report 55-145
The Fournile pegmatite area covers 32 sq. mi. in the western part of the Custer pegmatite mining district, Custer County, South Dakota. This area has been one of the major sources of sheet mica in the United States, especially between 1906 and 1911, and it has been a significant source...
Gravel and sand resources of the New England-New York region
Louis W. Currier
1955, Open-File Report 55-33
Deposits of sand and gravel are widespread in the New England-New York regions and constitute one of its principal mineral resources. Most of the pits are operated intermittently to supply local needs. Because of the great number and variety of known deposits, and because they have been worked at countless...
Geology of the Du Noir area, Fremont County, Wyoming
William Richard Keefer
1955, Open-File Report 55-81
The Du Noir area includes about 250 square miles in the northwestern part of the Wind River Basin, Fremont County, Wyoming. It is bounded on the south by the Wind River and Warm Spring Creek, which flow along the northeast flank of the Wind River Mountains, and on the north...
Preliminary report on the potential waterpower of Grant, Ptarmigan, Cooper and Crescent lakes on the Kenai Peninsula, near Seward, Alaska
Arthur Johnson
1955, Open-File Report 55-74
Grant, Ptarmigan, Cooper, and Crescent Lakes, located in the Kenai Mountains in the upper portion of the Kenai River Basin, approximately 25 miles to the north of Seward, present favorable opportunities for the development of waterpower. Grant and Ptarmigan Lakes can be made readily accessible by roads from the Seward-Anchorage...
Phosphate deposits in northern Alaska
William Wallace Patton Jr.
1955, Open-File Report 55-132
Deposits of low and medium grade phosphate rock were found recently at seven localities on the Arctic slope of Alaska. They were reported by field parties of the U.S. Geological Survey during the mapping of Naval Petroleum Reserve No. 4 and adjacent areas. The deposits are sedimentary in origin and...
