Sediment characteristics of five streams near Harrisburg, Pennsylvania, before highway construction
Lloyd A. Reed
1976, Water Supply Paper 1798-M
Rainfall, streamflow, sediment, and turbidity data are being collected as part of a study to evaluate the effects of highway construction on sediment discharge. The study is also designed to determine the effectiveness of different erosion-control measures in reducing sediment discharges. The study area, near Enola, Pa., consists of five...
Geochemical maps showing the distribution and abundance of tin in the Tanacross Quadrangle, Alaska
G.C. Curtin, G.W. Day, S.P. Marsh, R. M. O’Leary, R. B. Tripp
1976, Miscellaneous Field Studies Map 767-K
This series of geochemical maps shows the distribution of tin in three sample media: (A) the oxide residue (the oxalic-acid-leachable fraction) of the stream sediment, (B) the minus-80-mesh stream sediment, and (C) the ash of aquatic bryophytes (mosses). The geochemical data are plotted on a base map that shows generalized geology...

Distribution and abundance of lead in stream sediments and moraine debris, McCarthy Quadrangle, Alaska
Keith Robinson, C. M. McDougal, G.W. Day, Theodore Billings
1976, Miscellaneous Field Studies Map 773-G
A geochemical survey was conducted in the McCarthy quadrangle, Alaska, to identify areas containing anomalous concentrations of various metallic and nonmetallic elements. This study incorporates the results of analyses for lead, from 1,453 stream sediment and glacial moraine debris samples collected in the quadrangle, and analyzed by the U.S. Geological...

1976, Miscellaneous Field Studies Map 773-F
A geochemical survey was conducted in the McCarthy quadrangle, Alaska, to identify areas containing anomalous concentrations of various metallic and nonmetallic elements. This study incorporates the results of analyses for copper, from 1,454 stream sediment and glacial moraine debris samples collected in the quadrangle, and analyzed by the U.S. Geological...

Textural and mineralogical study of sandstones from the onshore Gulf of Alaska Tertiary Province, southern Alaska
Gary R. Winkler, Hugh McLean, George Plafker
1976, Open-File Report 76-198
Petrographic examination of 74 outcrop samples of Paleocene through Pliocene age from the onshore Gulf of Alaska Tertiary Province indicates that sandstones of the province characteristically are texturally immature and mineralogically unstable. Diagenetic alteration of framework grains throughout the stratigraphic sequence has produced widespread zeolite cement or phyllosilicate grain coatings...
Geochemical maps showing the distribution and abundance of beryllium in the Tanacross Quadrangle, Alaska
G.C. Curtin, G.W. Day, S.P. Marsh, R. B. Tripp
1976, Miscellaneous Field Studies Map 767-L
This series of geochemical maps shows the distribution of beryllium in three sample media: (A) the oxide residue (the oxalic-acid-leachable fraction) of the stream sediment, (B) the minus-80-mesh stream sediment, and (C) the ash of aquatic bryophytes (mosses). The geochemical data are plotted on a base map that shows generalized...

Jerry P. Eaton
1976, Open-File Report 76-374
The application of subtractive compensation to USGS seismic magnetic tape recording and playback systems was examined in a recent USGS Open-file report (1). It was found, for the standard (30 Hz) NCER multiplex system, that subtractive compensation utilizing a 4688 Hz reference signal multiplexed onto each data track was more...
