Preliminary interpretation of a seismic-refraction profile across the Large Aperture Seismic Array, Montana
C.A. Borcherdt, John C. Roller
1968, Open-File Report 68-15
A reversed seismic-refraction profile extending northeastward from Greycliff, Montana, across the Large Aperture Seismic Array (LASA) to Charleson, North Dakota, indicates that the crust of the earth consists of two layers with P-wave velocities of 6.1 km/sec and 6.7 km/sec, and that the upper-mantle velocity is 8.3 km/sec. The Mohorovicic...

1968, Professional Paper 516-E
An integrated geophysical study - comprising gravity, seismic refraction, and aeromagnetic surveys - was made of a 4,600-km2 area in Grand Teton National Park and vicinity, Wyoming, for the purpose of obtaining a better understanding of the structural relationships in the region. The Teton range is largely comprised of Precambrian...

Anomalous concentrations of gold, silver, and other metals in the Mill Canyon area, Cortez quadrangle, Eureka and Lander Counties, Nevada
James E. Elliott, John David Wells
1968, Circular 606
The Mill Canyon area is in the eastern part of the Cortez window of the Roberts Mountains thrust belt in the Cortez quadrangle, north-central Nevada. Gold and silver ores have been mined from fissure veins in Jurassic quartz monzonite and in the bordering Wenban Limestone of Devonian age. Geochemical data...
Chemical quality of surface waters in Devils Lake basin North Dakota, 1952-60
Hugh T. Mitten, C.H. Scott, Philip G. Rosene
1968, Water Supply Paper 1859-B
Above-normal precipitation in 1954, 1956, and 1957 caused the water surface of Devils Lake to rise to an altitude of 1,419.3 feet, its highest in 40 years. Nearly all the water entering the lake flowed through Big Coulee, and about three-fourths of that inflow was at rates greater than 100...
Gold distribution on the sea floor off the Klamath Mountains, California
George William Moore, Eli A. Silver
1968, Circular 605
Analyses of 82 samples collected from the surface of the continental shelf between the Oregon-California border and Eureka, Calif., indicate that the background gold content on this shelf is about 0.1 ppb (part per billion). Four anomalous tracts, which range in extent from 10 to 30 square kilometers, have gold...
An atomic-absorption method for the determination of gold in large samples of geologic materials
Gordon H. VanSickle, Hubert William Lakin
1968, Circular 561
A laboratory method for the determination of gold in large (100-gram) samples has been developed for use in the study of the gold content of placer deposits and of trace amounts of gold in other geologic materials. In this method the sample is digested with bromine and ethyl ether, the...
