Significance of Mesozoic radiolarians from the pre-Nevadan rocks of the southern Klamath Mountains, California
Ribbon cherts and siliceous tuffs of the North Fork and Rattlesnake Creek terranes of the Klamath Mountains yield Mesozoic radiolarians. Rocks of the North Fork terrane were previously considered to be of Paleozoic age and those of the Rattlesnake Creek to be of Paleozoic and Triassic age, on the basis of fossiliferous limestone bodies that are now considered to be exotic blocks. In both terranes,

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 Nuclea

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 alteration. The he
