Map showing high-purity silica sand of Middle Ordovician age in the Midwestern states
Keith B. Ketner
1979, Miscellaneous Field Studies Map 1097
Certain quartz sands of Middle Ordovician age in the Midwestern States are well known for their purity and are exploited for a wide variety of industrial uses. The principal Middle Ordovician formations containing high-purity sands are the St. Peter Sandstone which crops out extensively from Minnesota to Arkansas; the Everton...
Geologic interpretation of aeromagnetic map of the Seward and Blying Sound quadrangles, Alaska
J. E. Case, R. G. Tysdal, John W. Hillhouse, C. S. Grommé
1979, Miscellaneous Field Studies Map 880-D
An aeromagnetic survey of the Seward and northern part of the Blying Sound quadrangles was flown by Geometrics, Inc., during 1975-77 to provide magnetic data to aid in an appraisal of the mineral resources. Background details of the regional geology and major structures are described in a companion report by...
U.S. Geological Survey seismic engineering data report, 1974-75 records; strong-motion earthquake accelerograms digitization and analysis
A. G. Brady, V. Perez
1979, Open-File Report 79-929
This is the fourth of a series of reports planned to include the results of digitization and routine analyses of strong-motion earthquake accelerograms published by the U.S. Geological Survey. Serving as a model for this effort is the collection of data reports published by the Earthquake Engineering Research Laboratory of...
Restored stratigraphic cross sections and coal correlations in the Tongue River member of the Fort Union Formation, Powder River area, Montana
R. M. Flores
1979, Miscellaneous Field Studies Map 1127
Exposures of the lower two thirds of the Tongue River Member of the Paleocene Fort Union Formation were measured along the Powder River valley in southeastern Montana in the Moorhead and Birney-Broadus coalfields.  This report documents the stratigraphic variations, lateral continuity of partly eroded coal beds along the line of...
Geologic interpretation of the gravity anomaly map of the Seward and Blying Sound quadrangles, Alaska
J. E. Case, Robert Sikora, R. G. Tysdal, David F. Barnes, Robert Morin
1979, Miscellaneous Field Studies Map 880-C
For more than 20 years, gravity surveys have been conducted in the vicinity of Prince William Sound, the epicentral region of the great Alaska earthquake of March 27, 1964. Some of the major regional gravity anomalies were outlined by Thiel, Ostenso, Bonini (1960), and additional anomalies were defined by pre-...
Concentration and fractionation of hydrophobic organic acid constituents from natural waters by liquid chromatography
E.M. Thurman, Ronald L. Malcolm
1979, Water Supply Paper 1817-G
A scheme is presented which used adsorption chromatography with pH gradient elution and size-exclusion chromatography to concentrate and separate hydrophobic organic acids from water. A review of chromatographic processes involved in the flow scheme is also presented. Organic analytes which appear in each aqueous fraction are quantified by dissolved organic...
Seismicity map of the State of Georgia
C. W. Stover, B.G. Reagor, S. T. Algermissen, L.T. Long
1979, Miscellaneous Field Studies Map 1060
The earthquake data shown on this map and listed in table 1 are a list of earthquakes that were originally used in preparing the Seismic Risk Studies in the United States (Algermissen, 1969) which have been recompiled and updated through 1977. The data have been reexamined and intensities assigned where...
Directory to Federal, State, and local OCS-related activities and contacts
Mitre Corporation
1979, Open-File Report 79-1481
This directory identifies specific Federal, state, and local agencies involved with oil and gas activities on the Outer Continental Shelf (OCS). Current agency responsibilities and the mechanisms used for interacting with OCS activities are outlined in three groupings: (a) an overview of major Federal activities (Chapter 2) and the mechanisms...
