The Uralides and the motion of the Russian and Siberian Platforms
Warren B. Hamilton
1970, Bulletin of the Geological Society of America (81) 2553-2576
The Uralides—the late Precambrian and Paleozoic orogenic terrane between the Russian and Siberian Platforms—in part are exposed in the Ural Mountains, in the central Soviet Arctic, along the west edge of the Siberian Platform, and in southern Siberia and Kazakhstan, and in part are buried beneath the fill of the...
A possible bedrock source for obsidian found in archeological sites in northwestern Alaska
W. W. Patton Jr., T. P. Miller
1970, Science (169) 760-761
Recently discovered deposits of obsidian in the Koyukuk valley may be the long-sought-for source of obsidian found in archeological sites in northwestern Alaska. Obsidian from these deposits compares favorably in physical characteristics and sodium-manganese ratio with the archeological obsidian, and there is evidence that the deposits have been "mined" in...
Aspects of oil and gas operations on federal and Indian lands of interest to engineers
Charles J. Curtis
1970, Conference Paper, SPE Rocky Mountain regional meeting
It is always enjoyable to attend any meeting of the Society of Petroleum Engineers. I am happy to have this opportunity to speak to you because I believe that petroleum engineers can benefit from a better understanding of the Mineral Leasing Act and the regulations that implement the act insofar...

Observations of iceberg rafting in Glacier Bay, Alaska, and the identification of ancient ice-rafted deposits
A. Thomas Ovenshine
1970, Bulletin of the Geological Society of America (81) 891-894
Observations of icebergs in a modern glacial marine environment indicate that ancient rocks that received iceberg-rafted material should contain: (1) local concentrations of stones that originated when icebergs overturned, and (2) small pellets of till that were originally sediment filling the spaces between clear ice crystals.The till pellets are especially...
Pedro, Livengood, and Tanana: A study of place-names near Fairbanks, Alaska
Paul J. Sorvo
1970, Names (18) 185-190
In the early hours of March 30, 1867, Secretary of State William H. Seward completed the purchase of the remote and unexplored land known as Russian America, or Alaska. Discovered in 1741 by Vitus Bering, Alaska progressed from a Czarist colony to a territory of the United States, and finally,...
Aquilapollenites (Rouse) Funkhouser — Selected Rocky Mountain taxa and their stratigraphic ranges
Bernadine D. Tschudy, Estella B. Leopold
Robert M. Kosanke, Aureal T. Cross, editor(s)
1970, Book chapter, Symposium on palynology of the late Cretaceous and early Tertiary
The genus Aquilapollenites and its type species, A. quadrilobus, are redescribed, and the latter is illustrated. This report summarizes our present information on stratigraphic ranges of selected Rocky Mountain species and varieties of Aquilapollenites. Of the 17 taxa...
Palynology of the Cretaceous-Tertiary boundary in the northern Rocky Mountain and Mississippi Embayment regions
Robert H. Tschudy
Robert M. Kosanke, Aureal T. Cross, editor(s)
1970, Book chapter, Symposium on Palynology of the Late Cretaceous and Early Tertiary
In both the Rocky Mountain and the Mississippi Embayment regions it is often difficult to distinguish Upper Cretaceous from lower Tertiary rocks on the basis of physical characteristics; the transition can be recognized with relative ease, however, on the basis of abrupt qualitative changes in plant microfossils. Many Cretaceous species...
Effects of oil development in Arctic America
J. C. Reed
1970, Biological Conservation (2) 273-277
Large and important discoveries of petroleum were made in northern Alaska in 1968. The reserves were estimated then to be perhaps as much as ten thousand million barrels. Subsequent exploration has shown the resources to be much greater than was estimated earlier. Many...

Foraminiferal zonation and carbonate facies of Carboniferous (Mississippian and Pennsylvanian) Lisburne group, central and eastern Brooks range, Arctic Alaska
Augustus K. Armstrong, Bernard L. Mamet, J. Thomas Dutro
1970, American Association of Petroleum Geologists Bulletin (54) 687-698
The Lisburne Group carbonate rocks of the central and eastern Brooks Range contain foraminiferal assemblages assigned to zones of late Tournaisian (Osage) to early Moscovian (Atoka) age. Representatives of both Eurasiatic and American cratonic microfaunas permit correlation with the original Carboniferous type sections in western Europe as well as with...

1969, Professional Paper 542
This is the second in a series of six reports that the U.S. Geological Survey published on the results of a comprehensive geologic study that began, as a reconnaissance survey, within 24 hours after the March 27, 1964, Magnitude 9.2 Great Alaska Earthquake and extended, as detailed investigations, through several...
Effects of the earthquake of March 27, 1964, on various communities
George Plafker, Reuben Kachadoorian, Edwin B. Eckel, Lawrence R. Mayo
1969, Professional Paper 542-G
The 1964 earthquake caused wide-spread damage to inhabited places throughout more than 60,000 square miles of south-central Alaska. This report describes damage to all communities in the area except Anchorage, Whittier, Homer, Valdez, Seward, the communities of the Kodiak group of islands, and communities in the Copper River Basin; these...

1969, Circular 617
Sedimentary and volcanic rock units of Paleozoic and Mesozoic age, faults, and elongate bodies of intrusive rock, particularly serpentinites, have a dominant northeasterly trend in an area northwest of the Chulitna River between Eldridge Glacier and Bull River. The serpentinites locally contain abnormal (as much as 0.5 percent) concentrations of...

Gold analysis of grab and auger samples of bedrock taken along the new Ester Dome Road reveals that this road cuts several mineralized zones characterized by anomalous concentrations of gold. The results of a magnetometer traverse along this road indicate that the negative magnetic anomalies along the traverse may be...

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....
