Infectious nature of pancreatic necrosis
S. F. Snieszko, K. Wolf, J.E. Camper, L.L. Pettijohn
1959, Transactions of the American Fisheries Society (88) 289-293
To determine if pancreatic necrosis is a communicable disease of trout, lots of eyed brook trout eggs were obtained from four hatcheries. Pancreatic necrosis appeared spontaneously in trout from one of these hatcheries and the other strains were exposed to infection by suspension prepared from diseased fish. In all cases,...
Time-lapse motion picture technique applied to the study of geological processes
R. D. Miller, D. R. Crandell
1959, Science (130) 795-796
Light-weight, battery-operated timers were built and coupled to 16-mm motion-picture cameras having apertures controlled by photoelectric cells. The cameras were placed adjacent to Emmons Glacier on Mount Rainier. The film obtained confirms the view that exterior time-lapse photography can be applied to the study of slow-acting geologic processes....
Mummified seal carcasses in the McMurdo Sound region, Antarctica
T. L. Pewe, N.R. Rivard, G.A. Llano
1959, Science (130) 716-716
Information was collected on 90 mummified carcasses of the "crab-eater" seal in the ice-free areas of the McMurdo Sound region, Antarctica. The carcasses range from relatively well-preserved bodies to merely old, twisted, wind-dissected fragments of tissue. They are hard and dry and lie on the surface of the ground, mostly...
Role of fluid pressure in mechanics of overthrust faulting: II. Overthrust belt in geosynclinal area of western Wyoming in light of fluid-pressure hypothesis
William W. Rubey, M. King Hubbert
1959, GSA Bulletin (70) 167-206
Pressures of interstitial fluids significantly greater than the normal hydrostatic pressure are known in many parts of the world. Many occurrences are in thick sections of relatively young sediments; some are in areas that have been intensely deformed. Abnormal fluid pressures in the Gulf Coast region are associated with thick...
The petroleum potential of the emerged and submerged Atlantic coastal plain of the United States
J. E. Johnston, James Trumbull, G. P. Eaton
1959, Conference Paper, World Petroleum Congress Proceedings
Increasing geological and geophysical information about the Atlantic continental shelf of the United States is changing the basis for judging the area's petroleum potential. No nation can afford to overlook an area that overlies 175,000 cubic miles (730,000 km3) of possibly petroliferous sediments (including the emerged coastal plain), though the...
Water‐level fluctuations caused by Montana earthquake
Jose Alves Da Costa
1959, Eos, Transactions, American Geophysical Union (40) 346-346
The major earthquake of August 17, 1959, near the Montana‐Wyoming border had marked effects on water levels and artesian pressures in wells throughout the United States. Preliminary reports from field offices of the U. S. Geological Survey in 21 states show that water‐level fluctuations were automatically recorded in 136 observation...
Turtleback faults of Death Valley, California: A reinterpretation
Harald Drewes
1959, GSA Bulletin (70) 1497-1508
Turtlebacks are smooth, curved surfaces, which form north-northwestward-plunging elongate domes on the east side of Death Valley. These surfaces are roughly parallel to bedding or foliation of anticlines in Precambrian schist, gneiss, and marble. Late Cenozoic fan and playa deposits are faulted over these surfaces along the turtleback faults. Previously...
History of Imuruk Lake, Seward Peninsula, Alaska
David M. Hopkins
1959, GSA Bulletin (70) 1033-1046
A study of Imuruk Lake, a large, shallow lake in north-central Seward Peninsula, Alaska, illuminates the climatic history of northwestern Alaska and the tectonic history of central Seward Peninsula during Pleistocene and Recent time. Special interest attaches to the older lake sediments, because they contain evidence concerning the climate, fauna, and...
Granitization, migmatization, and fusion in the northern Entiat Mountains, Washington
D. F. Crowder
1959, GSA Bulletin (70) 827-878
A tabular quartz diorite complex extends along the Entiat Mountains, which form a southeast-trending spur of the Northern Cascade Mountains. The country rocks of the complex are biotite gneiss, probably derived from arkosic sedimentary rocks, and hornblende schist, probably derived from basic volcanic rocks. Their present mineral composition is typical of...
