Biostratigraphic classification of the marine Triassic in North America
N. J. Silberling, E. T. Tozer
1968, Book
Ammonoid faunas representative of every major part of Triassic time occur at one place or another in the marine Triassic strata of western and arctic North America. Though some intracontinental provincialism is evident, particularly among Lower and Middle Triassic ammonoid faunas, various local sections where parts of the faunal sequence...
Geology, paleomagnetism, and potassium-argon ages of basalts from Nunivak Island, Alaska
J. M. Hoare, William H. Condon, Allan Cox, G. Brent Dalrymple
1968, Book chapter, Studies in Volcanology
Geologic mapping, paleomagnetic stratigraphy, and potassium-argon dating were used to determine the time and volume relations of tholeiitic and alkalic basalt on Nunivak Island in the Bering Sea near the coast of Alaska. Volcanism on Nunivak Island occurred in distinct episodes separated by quiet intervals that lasted from 1.6 to...
SrRbK and Sr isotopic relationships in ultramafic rocks, southeastern Alaska
M. A. Lanphere
1968, Earth and Planetary Science Letters (4) 185-190
Geologic evidence suggests that a series of ultramafic complexes of the ‘Duke Island type’ located along a 560 km-long belt in southeastern Alaska crystallized from magmas of ultramafic composition. Some geologists have proposed that these magmas were derived by fractional fusion of...
Geologic history of the continental margin of North America in the Bering Sea
D.W. Scholl, E. C. Buffington, D.M. Hopkins
1968, Marine Geology (6) 297-330
The North American continental margin beneath the Bering Sea is nearly 1,300 km long and extends from Alaska to eastern Siberia. The margin is a canyon-scarred 3,200–3,400-m high escarpment separating one of the world's largest epicontinental seas (the shallow Bering Sea) and the...
Care, food consumption, and behavior of bald eagles used in DDT tests
N.J. Chura, P.A. Stewart
1967, The Wilson Bulletin (79) 441-448
Twenty-seven Bald Eagles captured in southeastern Alaska were used in feeding tests to determine the effects of DDT in the diet.....Trapping and housing of eagles are discussed. Various aspects of eagle behavior and handling techniques are also presented. Recommendations are made for preventing injuries and increasing the comfort of captive...
Ground breakage and associated effects in the Cook Inlet area, Alaska, resulting from the March 27, 1964, earthquake
Helen L. Foster, Thor N. V. Karlstrom
1967, Professional Paper 543-F
The great 1964 Alaska earthquake caused considerable ground breakage in the Cook Inlet area of south-central Alaska. The breakage occurred largely in thick deposits of unconsolidated sediments. The most important types of ground breakage were (1) fracturing or cracking and the extrusion of sand and gravel with ground water along...
Effects of the earthquake of March 27, 1964 on the communities of Kodiak and nearby islands
Reuben Kachadoorian, George Plafker
1967, Professional Paper 542-F
The great earthquake (Richter magnitude of 8.4–8.5) that struck south-central Alaska at 5:36 p.m., Alaska standard time, on March 27, 1964 (03:36, March 28, Greenwich mean time), was felt in every community on Kodiak Island and the nearby islands. It was the most severe earthquake to strike this part of...
Effects of the earthquake of March 27, 1964, at Seward, Alaska
Richard W. Lemke
1967, Professional Paper 542-E
Seward, in south-central Alaska, was one of the towns most devastated by the Alaska earthquake of March 27, 1964. The greater part of Seward is built on an alluvial fan-delta near the head of Resurrection Bay on the southeast coast of the Kenai Peninsula. It is one of the few...
Effects of the March 1964 Alaska earthquake on glaciers
Austin Post
1967, Professional Paper 544-D
The 1964 Alaska earthquake occurred in a region where there are many hundreds of glaciers, large and small. Aerial photographic investigations indicate that no snow and ice avalanches of large size occurred on glaciers despite the violent shaking. Rockslide avalanches extended onto the glaciers in many localities, seven very large...
Hydrologic effects of the earthquake of March 27, 1964, outside Alaska, with sections on Hydroseismograms from the Nunn-Bush Shoe Co. well, Wisconsin, and Alaska earthquake effects on ground water in Iowa: Chapter C in The Alaska earthquakes, March 27, 1964: effects on hydrologic regimen
Robert C. Vorhis, Elmer E. Rexin, R. W. Coble
1967, Professional Paper 544-C
The Alaska earthquake of March 27, 1964, had widespread hydrologic effects throughout practically all of the United States. More than 1,450 water-level recorders, scattered throughout all the 50 States except Connecticut, Delaware, and Rhode Island, registered the earthquake. Half of the water-level records were obtained from ground-water observation wells and...
