New potassium-argon data on the age of mineralization and metamorphism in the Willow Creek mining district, southern Talkeetna Mountains, Alaska
Miles L. Silberman, Bela Csejtey Jr., James G. Smith, Marvin A. Lanphere, Frederic H. Wilson
1978, Circular 772-B
The now largely abandoned Willow Creek mining district, southern Talkeetna Mountains, Alaska, produced nearly $18,000,000 in gold and minor silver between 1909 and the early 1950's. Mineralized quartz veins, which contain gold and silver along with minor quantities of base metals (in pyrite, galena, chalcopyrite, sphalerite, molybdenite, and arsenopyrite), cut...
Sea otter predation and community organization in the western Aleutian Island, Alaska
J. E. Estes, N. S. Smith, J. F. Palmisano
1978, Ecology (59) 822-833
Predation by the sea otter (Enhydra lutris) limits epibenthic invertebrates, especially sea urchins (Strongylocentrotus polyacanthus), in turn allowing a luxuriant development of the macroalgal canopy. Where sea otters are abundant, sea urchins are small and scarce in shallow water, and the association of fleshy macroalgae apparently is regulated by competition....

Arsenic in streams, stream sediments, and ground water, Fairbanks area, Alaska
Frederic H. Wilson, D. B. Hawkins
1978, Environmental Geology (2) 195-202
Arsenic concentrations of less than 5 ppb to as large as 1,260 ppb in stream waters and from 5 ppm to 4,000 ppm in stream sediments were found in the Pedro Dome-Cleary Summit area, Alaska. Waters from three of 20 wells sampled had arsenic concentrations exceeding the U.S. Public Health...
Induction of auroral zone electric currents within the Alaska pipeline
W.H. Campbell
1978, Pure and Applied Geophysics PAGEOPH (116) 1143-1173
The Alaskar pipeline is a highly conducting anomaly extending 800 miles (1300 km) from about 62?? to 69?? geomagnetic latitude beneath the most active regions of the ionospheric electrojet current. The spectral behavior of the magnetic field from this current was analyzed using data from standard geomagnetic observatories to establish...

Submarine faults and slides on the continental shelf, northern Gulf of Alaska
Paul R. Carlson, Bruce F. Molnia
1977, Marine Geotechnology (2) 275-290
Submarine faults and slides or slumps of Quaternary age are potential environmental hazards on the outer continental shelf (OCS) of the northern Gulf of Alaska. Most faults that approach or reach the seafloor cut strata that may be equivalent in age to the upper Yakataga Formation (Pliocene‐Pleistocene). Along several faults,...
Lisburne Group (Mississippian and Pennsylvanian), potential major hydrocarbon objective of Arctic Slope, Alaska
Kenneth J. Bird, Clifton F. Jordan
1977, AAPG Bulletin (61) 1493-1512
The Lisburne Group, a thick carbonate-rock unit of Mississippian and Pennsylvanian age, is one of the most widespread potential reservoir-rock units in northern Alaska. A comprehensive review of the Lisburne in the subsurface of the eastern Arctic Slope indicates attractive reservoir characteristics in a favorable source and migration setting where...
Bird atlasing in the United States
C.S. Robbins
1977, Polish Ecological Studies (3) 325-328
Since the Breeding Bird Survey provides an annual quantitative sample of about 75% of the 1? blocks of latitude and longitude in every state except Alaska and Hawaii, and 47% of the 1/2? blocks (equivalent on the average to a 48 km square), no national Atlas based on merely presence...
Platinum, palladium, and rhodium in volcanic and plutonic rocks from the Gravina-Nutzotin belt, Alaska
Norman J. Page, Henry C. Berg, Joseph Haffty
1977, Journal of Research of the U.S. Geological Survey (5) 629-636
The Gravina-Nutzotin belt of Middle (?) Jurassic to middle Cretaceous sedimentary and volcanic rocks in south and southeastern Alaska includes concentrically zoned ultramafic complexes known to contain platinum-group metals. Previous isotopic, petrologic, and geologic studies suggested a close relation in time and space between the volcanic rocks and the ultramafic...
Rare earths, thorium, and other minor elements in sphene from some plutonic rocks in west-central Alaska
Mortimer H. Staatz, Nancy M. Conklin, Isabelle K. Brownfield
1977, Journal of Research of the U.S. Geological Survey (5) 623-628
Sphene is an abundant accessory mineral in some abnormally radioactive plutonic rocks in west-central Alaska. Seven samples of sphene from four different areas in west-central Alaska contained from 20350 to 39180 parts per million total rare earths and 390 to 2000 ppm thorium. The lanthanide content in six of the...
