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...
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...
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...
