Deposition of the Tapeats Sandstone (Cambrian) in central Arizona Deposition of the Tapeats Sandstone (Cambrian) in central Arizona
Grain size, bedding thickness, dispersion of cross-stratification azimuths, and assemblages of sedimentary structures and trace fossils vary across central Arizona; they form the basis for recognizing six facies (A through F) in the Tapeats Sandstone. Five of these (A through E), present in western central Arizona, are marine deposits containing the trace fossil Corophioides; several...

Composition of Pacific Ocean ferromanganese nodules Composition of Pacific Ocean ferromanganese nodules
Bulk composition of ferromanganese nodules from the pelagic environment of the Pacific Ocean is apparently related to nodule-growth rate, sediment-accumulation rate, and biologic productivity in the overlying seawater. Nodules with a high MnFe ratio and high Ni and Cu concentrations tend to occur in areas where primary productivity in the surface layer of the ocean is high and the...

Report of status of Reactor Hazards Research Program: fiscal years 1976-1977 Report of status of Reactor Hazards Research Program: fiscal years 1976-1977
The Reactor Hazards Research Program is a Geological Survey program directed at expediting the safe siting and design of power reactors in the United States through topical and regional work on major geological hazards, particularly faulting, earthquake shaking, volcanism, and gross failure of foundation materials (table 1). It is complimentary to the more directed research sponsored by...

The landslide hazard in the San Francisco Bay region The landslide hazard in the San Francisco Bay region
Development in hilly or mountainous terrain has resulted in much landslide damage. Areas susceptible to landsliding can be recognized. Practices for minimizing landslides are presented.
