Hydrogeologic reconnaissance of Poro Point and vicinity, Luzon Island, Philippines
George Frank Worts
1964, Water Supply Paper 1608-E
In 1961 a reconnaissance of the geology and ground-water hydrology of Poro Point, on the west coast of Luzon Island, Philippines, was made on behalf of the U.S. Department of the Navy. Poro Point, which marks the northern end of Lingayen Gulf, is about half a mile wide and projects...
A magnetic anomaly of possible economic significance in southeastern Minnesota
Isidore Zietz
1964, Circular 489
An aeromagnetic survey in southeastern Minnesota by the U. S. Geological Survey in cooperation with the State of Minnesota has revealed a high-amplitude, linear, and narrow magnetic feature that suggests a possible source of Precambrian iron-formation of economic value. For the past few years the U. S. Geological Survey has...
Magnetic properties of Pd, Pd-H and Pd-D from 300 degrees K to 4.2 degrees K
Arthur N. Thorpe
1964, Open-File Report 64-151
The magnetic properties of many substances first studied seriously by Faraday have played an important role in our modern technology. In particular, the magnetic properties of the transition elements are of great importance in the understanding of the electronic band form of these elements. Once the electronic band form is...
Determination of ammonium citrate-soluble cobalt in soils and sediments
Frank Cogswell Canney, G.A. Nowlan
1964, Open-File Report 64-30
A rapid field method for the determination of cold-extractable cobalt in soils and sediments has been developed for use in geochemical prospecting. Readily available cobalt is dissolved by treating the sample with an aqueous ammonium citrate-hydroxylamine hydrochloride solution; the filtered citrate extract is then treated with 2-nitroso1-naphthol to form a...
Seismic refraction survey in the Great Miami River Valley and vicinity, Montgomery, Warren, and Butler Counties, Ohio
Joel S. Watkins, Andrew M. Spieker
1964, Open-File Report 64-161
As part of a continuing program to define the thickness and extent of water-bearing sand and gravel deposits in southwestern Ohio, the U.S. Geological Survey, in cooperation with the Ohio Division of Water and The Miami Conservancy District, completed a seismic refraction survey of the Great Miami River valley and...
Seismic study of coal mine bumps, Carbon and Emery Counties, Utah
C. Richard Dunrud, Frank W. Osterwald
1964, Open-File Report 64-45
A continuously recording seismic network was constructed in 1962 by the U.S. Geological Survey to locate epicenters and record incidence of bumps (bounces, rock bursts) that occur in the bituminous coal mines of the Book Cliffs coal field near Sunnyside, Utah. The coal is mined because of its value as...
Preliminary report on the geologic and geophysical investigations of the Loveland Basin landslide, Clear Creek County, Colorado
Charles Sherwood Robinson, R. D. Carroll, Fitzhugh T. Lee
1964, Open-File Report 64-135
Geologic and geophysical investigations of the Loveland Basin landslide, which formed at the cut for the east portal of the Straight Creek tunnel, were made by the U.S. Geological Survey in cooperation with the U.S. Bureau of Public Road and the Colorado Department of Highways. The investigations indicate that the...
