Bathymetry and isopach map of stratified Holocene sediments of Nuka Bay, Alaska
Erk Reimnitz, Roland E. von Huene
1969, Open-File Report 69-219
The bathymetric chart of the Nuka Bay area, Alaska, is based on U.S.C.&G.S. Chart 8530, and over 750 km of additional sounding lines made in 1965 and in 1968. Continuous reflection seismic records made along the same tracks as the bathymetric profiles served as the basis for the Isopach map....
Foraminiferal zonation and carbonate facies of the Mississippian and Pennsylvanian Lisburne Group, central and eastern Brooks Range, Arctic Alaska
Augustus K. Armstrong, Bernard L. Mamet, J. Thomas Dutro Jr.
1969, Open-File Report 69-14
The Lisburne Group carbonates of the central and eastern Brooks Range contain foraminiferal assemblages assigned to zones of Osage [late Tournaisian], Early Mississippian, to Atoka [early Moscovian], Middle Pennsylvanian age. Representatives of both Eurasiatic and American cratonic microfaunas permit correlation with the original Carboniferous type sections in western Europe as...
Paleogene floras from the Gulf of Alaska
Jack A. Wolfe
1969, Open-File Report 69-323
Numerous collections of fossil plants from the Gulf of Alaska region were obtained from rocks that are well dated by marine mollusks. The mollusks indicate that the oldest possible age for the lowest plant assemblage is middle Eocene (Domengine) and that the youngest possible age for the highest Paleogene plant...
Preliminary geologic interpretation of aeromagnetic data in the Yakutat district, Alaska
Gordon R. Johnson, George Plafker
1969, Open-File Report 69-134
An aeromagnetic survey covering portions of the Yakutat Feveland region in south-central Alaska was made to delineate concentrations of magnetic minerals possibly associated with heavy mineral placers in beach sands and raised beach ridges. However, the larger magnetic anomalies do not correlate with the beach placers in the surveyed area....
Metalliferous deposits near Granite Mountain, eastern Seward Peninsula, Alaska
Thomas P. Miller, Raymond L. Elliott
1969, Circular 614
New deposits of lead, zinc, and silver were found in a large altered zone 18 miles long and 2 to 5 miles wide near Quartz Creek west of Granite Mountain in the eastern Seward Peninsula, Alaska. New deposits of molybdenum, bismuth, and silver were found associated with a previously reported...
Tectonics of the March 27, 1964, Alaska earthquake
George Plafker
1969, Professional Paper 543-I
The March 27, 1964, earthquake was accomp anied by crustal deformation-including warping, horizontal distortion, and faulting-over probably more than 110,000 square miles of land and sea bottom in south-central Alaska. Regional uplift and subsidence occurred mainly in two nearly parallel elongate zones, together about 600 miles long and as much...
