Gold geochemical anomaly in the Cortez district, Nevada
Ralph Leroy Erickson, G.H. Van Sickle, H. M. Nakagawa, J. H. McCarthy, Kam Leong
1966, Circular 534
An area in the Cortez district, Nevada, previously established to be anomalous in arsenic, antimony, and tungsten has been found to be anomalous also in mercury and gold. Samples from narrow quartz veins, calcite veins, and shear zones in partially silicified limestone in the lower plate of the Roberts thrust...
Regional trends in water-well drilling in the United States
Gerald Meyer, Granville G. Wyrick
1966, Circular 533
Between the towns of Macon and Taylorville in central Illinois lies a ridge that is part of a system of ridges and knolls largely composed of sand and gravel. This ridge contains an important aquifer. An extensive electrical earth resistivity survey was conducted over the ridged-drift aquifer. Inversion of the...
The interior of the Earth, an elementary description
Eugene C. Robertson
1966, Circular 532
Evidence on the structure and composition of the earth's interior comes from (1) observations of surface rocks, (2) geophysical data from earthquakes, flow of heat from the interior, the magnetic field, and gravity, (3) laboratory experiments on surface rocks and minerals, and (4) comparison of the earth with other planets,...
The promise of precise borehole gravimetry in petroleum exploration and exploitation
Thane Hubert McCulloh
1966, Circular 531
This report provides comprehensive information on the geology, geohydrology, and mineral resources of Boone and Winnebago Counties for use in resource-based land-use planning and development. Data on the composition, thickness, and regional distribution of glacial drift and bedrock materials were used to construct maps of: geologic materials to a depth...

Tritium rainout over the United States in 1962 and 1963
G.L. Stewart, C.M. Hoffman
1966, Circular 520
The magnitude and frequency of floods are defined regionally for small streams (drainage This report describes the tritium sampling network established by the U.S. Geological Survey. Tritium rainout data are included for 1962 and 1963 precipitation collected at 15 stations in the United States and Puerto Rico. These data are...
Gravimetric effects of petroleum accumulations--A preliminary summary
Thane Hubert McCulloh
1966, Circular 530
Negative gravity anomalies of very local extent and with amplitudes of 1.2 milligals or less have been observed over some known petroleum and natural gas fields in southern California and South Dagestan, U.S.S.R. Field evidence, laboratory measurements, and theory indicate that these anomalies are mainly the result of hydrocarbon pore...

The changing pattern of ground-water development on Long Island, New York
Ralph C. Heath, B. L. Foxworthy, Philip M. Cohen
1966, Circular 524
Ground-water development on Long Island has followed a pattern that has reflected changing population trends, attendant changes in the use and disposal of water, and the response of the hydrologic system to these changes. The historic pattern of development has ranged from individually owned shallow wells tapping glacial deposits to...

Tectonic creep in the Hayward fault zone, California
Dorothy H. Radbruch-Hall, M. G. Bonilla
1966, Circular 525
Tectonic creep is slight apparently continuous movement along a fault. Evidence of creep has been noted at several places within the Hayward fault zone--a zone trending northwestward near the western front of the hills bordering the east side of San Francisco Bay. D. H. Radbruch of the Geological Survey and...
