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...

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.

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...

Implications of a magnetic model of the Long Valley caldera, California Implications of a magnetic model of the Long Valley caldera, California
A quantitative magnetic model of Long Valley, California, shows that the magnetic field above this caldera is dominated by intracaldera Bishop tuff, part of the ash flow tuff whose eruption precipitated the caldera collapse. We propose that about half of the 350 km3 of intracaldera Bishop tuff, or that part beneath the resurgent dome, has been subjected to extensive hydrothermal...

Natural remanent magnetization, mag¬netic properties, and oxidation of titanomagnetite in basaltic rocks from DSDP Leg 34 Natural remanent magnetization, mag¬netic properties, and oxidation of titanomagnetite in basaltic rocks from DSDP Leg 34
We have made paleomagnetic measurements and investigated the magnetic mineralogy of 24 samples of basalt and diabase from Sites 319, 320, and 321 on the Nazca plate. Sample distributions, locations, and ages of overlying sediments are as follows: Site 319, Hole 319, lat 13°01.04'S, long 101°31.46'W, 2 samples, early Miocene (N8); Site 319, Hole 319A, (same coordinates and age), 12...
