Ground-water exploration in the Bosque del Apache Grant, Socorro County, New Mexico
James B. Cooper
1968, Open-File Report 68-63
Test drilling along the Rio Grande in the Bosque del Apache Grant in Socorro County, New Mexico has shown that the area is hydrologically complex and that the quality of the ground water varies from saline to fresh within short distances both laterally and vertically. Nearly all of the riverside...
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...
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...
A mineral reconnaissance of the Jabal Khida quadrangle, Saudi Arabia
Jesse William Whitlow
1968, Open-File Report 68-325
Reconnaissance of the Jabal Khida quadrangle shows that granite and granodiorite (unit gg), biotite and hornblende granite (unit gr) and alkalic and paralkalic granit (unit gp) divisions for granites seems valid, but that two ages of metamorphic and extrusive rocks are mapped as the Halaben formation (unit ha/hc). Semiquantitative analyses of...
Summary of floods in the United States during 1962
J.O. Rostvedt
1968, Water Supply Paper 1820
This report describes the most outstanding floods in the United Spates during 1962. The most damaging floods during the year occurred in February in southern Idaho and northern Nevada and Utah, and during the latter part of February and the early part of March in Kentucky and in the Cumberland...
Application of dislocation theory to analysis of vertical displacements at the ground surface caused by the Duryea event
G.E. Brethauer
1968, Open-File Report 68-20
Dislocation theory is used in an analysis that explains measured vertical displacements across a fault near the Duryea underground nuclear explosion. The difference between the measured vertical displacement and the theoretically predicted vertical displacement caused by cavity formation is termed the residual vertical displacement. The residual vertical displacement is, therefore,...
Dispersive multispectral scanning; a feasibility study
J. Braithwaite
1968, Open-File Report 68-19
Optical-mechanical line scanners can be used from aircraft and satellites to obtain strip maps of the surface over which the vehicle passes. The feasibility of combining wavelength dispersing techniques with such scanning techniques has been studied. This combination makes it possible to obtain spectral and spatial information simultaneously. Appropriate data...
