A study of uranium favorability of Cenozoic sedimentary rocks, Basin and Range Province, Arizona: Part I. General geology and chronology of pre-late Miocene Cenozoic sedimentary rocks
Robert Bryan Scarborough, Jan Carol Wilt
1979, Open-File Report 79-1429
This study focuses attention on Cenozoic sedimentary rocks in the Basin and Range Province of Arizona. The known occurrences of uranium and anomalous radioactivity in these rocks are associated with sediments that accumulated in a low energy environment characterized by fine-grained clastics, including important tuffaceous materials, and carbonate rocks. Most...
Magnetometer traverse on Plum Island near Newburyport, Massachusetts
Robert W. Simpson, Wallace A. Bothner
1979, Open-File Report 79-435
Several large faults of regional tectonic significance circle around Boston and disappear offshore at Plum Island south of Newburyport, Massachusetts (Castle and others, 1976; Barosh and others, 1977). The traces of these faults are, in places, well defined by aeromagnetic anomalies (Harwood and Zietz, 1977), The purpose of this traverse...
Preliminary geomagnetic data, College Observatory, Fairbanks, Alaska: January 1979
J.B. Townshend, J.E. Papp, S.P. Tilton
1979, Open-File Report 79-300-A
The preliminary geomagnetic data included here is made available to scientific personnel and organizations, as part of a cooperative effort and on a data exchange basis because of the early need by some users. To avoid delay, all of the data is copied from original forms processed at the observatory;...
Physical and chemical properties of San Francisco Bay waters, 1969-1976
Richard E. Smith, Raynol E. Herndon, Dana D. Harmon
1979, Open-File Report 79-511
Basic data on the physical and chemical properties of San Francisco Bay are presented here. Samples were collected over the period 1969-1976 at approximately six-week intervals at 36 stations. The stations were located along the axis of the Bay from Calaveras Point in South San Francisco Bay to the town...
Hydrologic evaluation of the Alton reclamation-study site, Alton coal field, Utah
G. W. Sandberg
1979, Open-File Report 79-346
This investigation was conducted from July 1974 to September 1977 to define general hydrologic conditions at a reclamation-study site in the Alton coal field near Kanab, Utah. The average annual streamflow through the area was less than 600 acre-feet (0.7 cubic hectometer), and the water carried little sediment except during...
Geochemical and generalized geologic map showing distribution and abundance of antimony and niobium in stream sediments, Chandalar 1° by 3° quadrangle, Alaska
S.P. Marsh, D.E. Detra, S.C. Smith
1979, Miscellaneous Field Studies Map 878-H
This geochemical map shows the distribution and abundance of antimony (Sb) and niobium (Nb) in -80 mesh (177 micrometers) stream sediment samples in the Chandalar quadrangle, Alaska. The map is one of a series of geochemical maps that together with the background information circular (Reiser and others, 1978) comprise the folio...
Saltwater-barrier line in Florida: Concepts, considerations, and site examples
Jerry L. Hughes
1979, Water-Resources Investigations Report 79-75
Construction of canals and enlargement of streams in Florida has been mostly to alleviate impact of floods and to drain wetlands for development. Land drainage and heavy pumpage from coastal water-table aquifers has degraded potable ground and surface water with saltwater. Control of saltwater intrusion is possible through implementation of...
Direct analysis of RDX and TNT in water by high-performance liquid chromatography
D.F. Goerlitz
1979, Open-File Report 79-916
A method for the determination of RDX (1,3,5-trinitro-1,3,5-triazacyclohexane) and TNT (2,4,6-trinitrotoluene) directly in water is given. The high-performance liquid chromatographic technique permits detection down to 0.1 microgram per liter in filtered water. No ancillary extraction or concentrating procedures are used....
