K-feldspar content of Jurassic and Cretaceous graywackes of northern Coast Ranges and Sacramento Valley, California
Edgar Herbert Bailey, William Porter Irwin
1959, American Association of Petroleum Geologists Bulletin (43) 2797-2809
Graywackes of Late Jurassic to Late Cretaceous age are the predominant rocks in the northern Coast Ranges and the western Sacramento Valley provinces in California. These graywackes are similar in appearance, but their content of K-feldspar, which can be readily estimated after selective...
Age of marginal Wisconsin drift at Corry, northwestern Pennsylvania
J.B. Droste, M. Rubin, G. W. White
1959, Science (130) 1760-1760
Marl began to accumulate about 14,000 years ago, as determined by radiocarbon dating, in a pond in a kettle hole in Kent drift at Corry, Pa., 9 miles inside the Wisconsin drift margin. This radiocarbon age represents the minimum time since the disappearance of the ice from Corry and confirms...
Peneconcordant uranium deposit: A proposed term
W.I. Finch
1959, Economic Geology (54) 944-946
The term peneconcordant is proposed to describe the form of the numerous and highly productive U deposits in sedimentary rocks of the Colorado Plateau, Wyoming, the Dakotas, and Texas. Peneconcordant U deposits are tabular, lenticular, or irregularly-shaped masses of widely differing size that are, in general, concordant to the gross...
Some aspects of the origin of the Ironwood iron-formation of Michigan and Wisconsin
N.K. Huber
1959, Economic Geology (54) 82-118
The Ironwood iron-formation of the Gogebic Range of Michigan and Wisconsin is made up of several rock types, each of which is characterized by a different iron-rich mineral: hematite, magnetite, pyrite, iron carbonate, or iron silicate (minnesotaite, stilpnomelane). Where the Ironwood iron-formation is relatively unaltered the Plymouth, Norrie, and Anvil...
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...
