Geology of the Cupsuptic quadrangle, Maine
David S. Harwood
1966, Open-File Report 66-57
The Cupsuptic quadrangle, in west-central Maine, lies in a relatively narrow belt of pre-Silurian rocks extending from the Connecticut River valley across northern New Hampshire to north-central Maine. The Albee Formation, composed of green, purple, and black phyllite with interbedded-quartzite, is exposed in the core of a regional anticlinorium overlain...
Seismic refraction surveys in the vicinity of Eagle City, Clark County, Ohio
Jerry H. Hassemer, Joel S. Watkins, Norman G. Bailey
1966, Open-File Report 66-58
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, in the summer of 1964 completed a seismic refraction survey in the vicinity of Eagle and Tremont...
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...
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...
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...
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...
