Relationship between physical condition of the carbonate fraction and sediment environments: Northern Puerto Rico shelf
O. H. Pilkey, E.I. Fierman, James V. A. Trumbull
1979, Sedimentary Geology (24) 283-290
Each of three sediment types recognizable on the northern Puerto Rico shelf and beaches is characterized by calcareous material in different physical condition. Dark terrigenous sand is accumulating at a relatively rapid rate and has a carbonate fraction containing fresh-appearing angular particles. The pure-carbonate skeletal-sand sediment type has a much...
Clay mineralogy, fine-grained sediment dispersal, and inferred current patterns, lower Cook Inlet and Kodiak shelf, Alaska
James R. Hein, Arnold H. Bouma, Monty A. Hampton, Ross C. Robin
1979, Sedimentary Geology (24) 291-306
Because lower Cook Inlet and Kodiak shelf are being explored and developed for their petroleum resources, it is essential for environmental reasons to understand the sediment dispersal routes and current patterns. The Susitna River flows into upper Cook Inlet and is the source of clay minerals in Holocene deposits found...
Research in the United States relative to geochemistry and health
W.L. Petrie, H.L. Cannon
1979, Physics and Chemistry of the Earth (11) 829-847
Increasing concern regarding the effects of the geochemical environment on health in the United States has fostered research studies in a number of universities and government agencies. The necessity to evaluate the effects of natural and man-made elemental excesses in the environment on health requires the establishment of requirements and...
The determination of lead in 13 USGS standard rocks
P. J. Aruscavage, E.Y. Campbell
1979, Talanta (26) 1052-1054
Lead was determined in 13 U.S. Geological Survey standard rocks by graphite furnace atomization and atomic-absorption spectrometry after extraction of lead with diethylammonium diethyldithiocarbamic acid. An analysis of variance of the results obtained from a random sampling of three different bottles of each standard rock showed no heterogeneity among bottles,...

Maps showing late Pleistocene and Holocene evolution of the South Texas continental shelf
Carroll A. Pyle, Henry L. Berryhill Jr., Anita R. Trippet
1979, Miscellaneous Field Studies Map 1134
Interpretation of acoustical profiles has provided insight into the late Quaternary geologic history of the Continental Shelf off South Texas. (See the geographic index map on sheet 1 for location of the area studied.) The profiles reveal the interplay of tectonism, sedimentation, and cyclic fluctuations of sea level in the...

1979, Open-File Report 79-579
The purpose of this report is to present the results of geotechnical, textural, and chemical tests performed on samples from the upper Continental Slope, northern Gulf of Mexico.The samples were collected by a piston corer up to 12 m (40 ft.} in length with a head weight of 908 kg...
Possible reestablishment of sawtimber production following mining in the Osceola National Forest, an analysis of the state-of-the-art, February 9, 1978
J. Scott Boyce
1979, Open-File Report 79-524
There is a good possibility that sawtimber production could be reestablished on the Osceola National Forest. Engineering technology that is coming on-line should allow the establishment of land/water relationships that meet the requirements of desired tree species. Information available on soil-plant relationships indicate an absence of phytotoxic materials in various...
Surface water environment in the area of the San Juan Basin regional uranium study, New Mexico, Colorado, Arizona, and Utah
Mark William Busby
1979, Open-File Report 79-1499
Streamflows in the lowland areas of the San Juan Basin are highly variable, responding to short-duration, high-intensity thunderstorms occurring in the late spring and summer. The thunderstorms can cause floods of large magnitude, but of localized extent. Most streams of the lowlands are ephemeral or intermittent. Streams of the high...

Alaskan papers and abstracts published in American Association of Petroleum Geologists Bulletin, 1950-1978, indexed by quadrangle
Edward Huntington Cobb
1979, Open-File Report 79-1475
This open—file report lists all papers and abstracts on the geology and mineral resources of Alaska published in the American Association of Petroleum Geologists Bulletin from 1950 through 1978. They are listed by the quadrangles (scale 1:250,000) into which Alaska has been subdivided for topographic mapping (p. 2).Reports that deal...
Water-quality conditions in the New River, Imperial County, California
James G. Setmire
1979, Water-Resources Investigations Report 79-86
The New River, when entering the United States at Calexico, Calif., often contains materials which have the appearance of industrial and domestic wastes. Passage of some of these materials is recognized by a sudden increase in turbidity over background levels and the presence of white particulate matter. Water samples taken...

A uranium occurrence in the Tertiary Kootznahoo Formation on Kuiu Island, southeast Alaska
Kendell A. Dickinson
1979, Open-File Report 79-1427
Radioactive anomalies as high as 50 times background and uranium-bearing samples were discovered in parts of the nonmarine Tertiary Kootznahoo Formation in southeast Alaska by K. A. Dickinson and John Mitchell. Samples containing as much as 1300 ± 400 ppm uranium, measured by beta eU, were found. These samples have...

1979, Open-File Report 79-1482
For several years, dissolved oxygen in the L'Anguille River has been reduced to concentrations of less than 5.0 milligrams per liter during the summer and fall. The dissolved-oxygen reduction is due only in part to the municipal-waste discharges which enter the river. In addition, concentrations of pesticides have been reported...

1979, Open-File Report 79-1302
Radioactive springs and wells at 33 localities in the States of Colorado, Utah, Arizona, and New Mexico have been studied and sampled to obtain geochemical data to determine whether such data are useful in a uranium exploration program. Most samples were collected from mineral-rich springs probably related to hydrothermal systems...
Water-quality characteristics of streams in forested and rural areas of North Carolina
Clyde E. Simmons, Ralph C. Heath
1979, Water-Resources Investigations Report 79-108
Data collected in North Carolina during 1973-78 from a statewide network of 39 rural sampling sites were used to define unpolluted or baseline stream quality. The basins were 90 to 100 percent forested and, except for the unknown effects of air pollution, were relatively unaffected by man 's activities. Five...
