Brief comparison of some technological and environmental aspects of large-scale surface and underground mining of oil shale, Piceance Creek Basin, Colorado
Comparison of several aspects of surface and underground methods of mining for large-scale oil shale extraction in the Piceance Creek Basin suggests that surface mining techniques may have several advantages over underground methods. For a production level of one million barrels of shale oil per day, potential advantages include those related to economics, environmental effects, and the overall na

Geomagnetic paleointensities from excursion sequences in lavas on Oahu, Hawaii
Paleomagnetic data demonstrating three late Tertiary excursions in the direction of the geomagnetic field recorded in sequences of basaltic lavas on the island of Oahu, Hawaii were published by R. R. Doell and G. B. Dalrymple in 1973. We have determined geomagnetic paleointensities by the Thelliers' method for 14 lavas from the three sites. During these experiments, considerable difficulty was enc

Paleomagnetic constraints on the interpretation of early Cenozoic Pacific Northwest paleogeography
Widespread Cenozoic clockwise tectonic rotation in the Pacific Northwest is an established fact; however, the geologic reconstructions based on these rotations are the subject of continuing debate. Three basic mechanisms have been proposed to explain the rotations: (1) simple shear rotation of marginal terranes caught in the dextral shear couple between oceanic plates and North America; (2) rotati

Implications of paleomagnetism for the tectonic history of the Eastern Klamath and related terranes in California and Oregon
Paleomagnetic study of Permian to Jurassic volcanic and sedimentary strata of the Eastern Klamath terrane has shown the remanent magnetism of these rocks to be prefolding and primary. The Permian and Triassic rocks are both indicated to have rotated 100° clockwise, while the Jurassic strata have rotated 60° clockwise. The respective amounts of rotation for Permian and Jurassic strata are similar a

Book review: Geomagnetism of baked clays and recent sediments
This book is an outgrowth of the symposium entitled “Time Scales of Geomagnetic Secular Variations,” which was held at the 4th Assembly of the International Association of Geomagnetism and Aeronomy (Edinburgh, U.K., August 1981). The volume includes many of the papers presented, which described paleomagnetic results from both archeologic materials and Holocene geologic deposits, as well as contrib

Statistical relations among earthquake magnitude, surface rupture length, and surface fault displacement
In order to refine correlations of surface-wave magnitude, fault rupture length at the ground surface, and fault displacement at the surface by including the uncertainties in these variables, the existing data were critically reviewed and a new data base was compiled. Earthquake magnitudes were redetermined as necessary to make them as consistent as possible with the Gutenberg methods and results,
