The accompanying report on the iron deposits of the North American continent also includes information concerning the deposits of the West Indies. The geogrphic order of desription is as follows: Alaska, Canada, United States, Mexico, Cuba, and Puerto Rico.A map of each country shows the generalized geologic pattern of the...
Preliminary report of investigations of springs in the Mogollon Rim region Arizona
J. H. Feth
1954, Open-File Report 54-339
The Geological Survey has made a reconnaissance of springs in the Mogollon Rim region in central Arizona. This region is the source of much of the water in the Gila, Salt, and Verde Rivers. The region has not previously been systematically studied with respect to the occurrence of ground water....
Progress report (1953) on the revision of Washington's Chemical analyses of igneous rocks (U.S.G.S. Prof. Paper 99), presented at the First International Symposium on Geochemistry, under the auspices of the International Union of Chemistry, in Zurich, August 11-13, 1953
Marjorie Hooker
1954, Open-File Report 54-129
In October of last year, vhen I was here in Zurich, it was my privilege to talk with Professor Niggli about the revision of Washington's "Chemical analysis of igneous rocks" which the United States Geological Survey is undertaking. It was then that he suggested the possibility of a progress report...
Landslide conditions along the Ferry County highway parallelling Lake Roosevelt from Kettle Falls to the mouth of the Spokane River, Washington
Fred O. Jones
1954, Open-File Report 54-136
As part of the program of the U.S. Geological Survey, landslides are being studied in several localities in the United States. These studies are directed toward assembling criteria for recognition of landslides, classification, and cataloging of remedial or control methods that have been effective.  In the gorge of the Columbia...
Alunitic alteration at Marysvale, Utah
Raymond Laurence Parker
1954, Open-File Report 54-225
Deposits of alunited in the Marsvale region Utha, are nearly all confined to the Bullion Canyon Volcanics of Tertiary age. the deposits consist of two types, alunited veins and irregular alunite replacement bodies. The vein deposits are restrcited to the vicinity of Alunite Ridge southwest of Marysvale in the Tushar...

Vernon Edward Scheid
1954, Open-File Report 54-266
The Stockton and Stanley Hill deposits, Kootenai County, Idaho, are about 25 to 30 miles east of Spokane, Wash. During World War II, the areas were studied by the U. S. Geological Survey in cooperation with the U. S. Bureau of Mines. The Bureau of Mines hand-augered 162 holes and...

1954, Open-File Report 54-241
This report presents in preliminary form the results of a reconnaissance geologic investigation of the Malaspina district, undertaken by the United States Geological Survey as part of a project to investigate the petroleum possibilities of the Gulf of Alaska Tertiary province. (See index map.) ...
Geology of the Eureka pegmatite, Pennington County, South Dakota
Roy Eldon Roadifer
1954, Open-File Report 54-256
The Eureka Pegmatite, two miles southeast of Keystone, Pennington County, South Dakota, is a small but possibly valuable zoned body containing more than 85,000 tons of coarse-grained granite-pegmatite rock.The mica in the pegmatite is probably not of any great importance, but the potash feldspar and beryl may comprise a considerable...
Geology of parts of the Johnny Gulch quadrangle, Montana
Val L. Freeman
1954, Open-File Report 54-92
An area of about 35 square miles, situated about 30 miles southeast of Helena, Montana, was mapped during the summer of 1952 at a scale of l:24, 000. The area includes a part of the eastern foothills of the Elkhorn Mountains, and is underlain by sedimentary mad volcanic rocks of...
The physical behavior and geologic control of radon in mountain streams
Allen Stuart Rogers
1954, Open-File Report 54-259
Radon distribution ratio determinations in an all-water system were made. They checked very closely with those done by Kofler in 1913. The distribution of radon in stream waters and related springs was investigated in the Wasatch Mountains adjacent to Salt Lake City, Utah, and in a part of the Weber...
Contribution to the study of the physico-chemical structure of Clais
Remy Hebert, S. E. Britt (translator)
1954, Open-File Report 54-28
The Cormeilles-en-Parisis hill shows one of the best geologic sections of the Paris region. The 80 meter high working face of the quarry exposes the complete section of the "Ludian" [the youngest beds of the Eocene] with its alternations of the marl and gypsum. Above is the sequence of supra-gypseous...
Magnetite deposits at Tuxedni Bay, Alaska
Arthur Grantz
1954, Open-File Report 54-103
The magnetite deposits on an island in Tuxedni Bay occur in contact-metamorphosed volcanic and sedimentary rocks near their contact with a quartz diorite batholith which underlies large areas of the adjacent Aleutian Range. The deposits are pyrometasomatic in origin and are localized along northeast-trending fractures. The eastern deposit is a...
