Magnetotelluric soundings in the southwestern United States Magnetotelluric soundings in the southwestern United States
Twelve magnetotelluric soundings were made along a 460-mile traverse in the southwestern United States. Spectral analysis of digitized graphic records was used to determine apparent resistivities and phase differences for periods in the range 10-1,000 sec. The geoelectric section to depths of the order of 300 km was found to be divided into three principal layers. The layer nearest the...

Ordovician, Silurian, and Devonian biostratigraphy of east-central Alaska Ordovician, Silurian, and Devonian biostratigraphy of east-central Alaska
A predominantly shale and chert sequence has been mapped from the Canadian border at Latitude 65°00′ N. to the Nation River about 25 miles northwest. It has Ordovician and Silurian graptolites in the lower half, and Middle Devonian corals and Upper Devonian spores in the upper half. The lower half of the sequence consists of about 400 to 900 feet of predominantly dark gray graptolitic...

Subdivision of the San Lorenzo Formation (Eocene and Oligocene) west-central California Subdivision of the San Lorenzo Formation (Eocene and Oligocene) west-central California
The San Lorenzo Formation was for many years considered synonymous with Oligocene Series. The formation name was extended, incorrectly in most cases, to rocks as far north as British Columbia and as far south as southern California. The formation in its type area was never adequately studied, resulting in fallacious concepts of its faunas and erroneous correlations. The San Lorenzo...
