R. L. Erickson, S.P. Marsh
1971, Miscellaneous Field Studies Map 315
Detailed geologic and geochemical studies of the four 7 1/2-minute quadrangles that make up the Edna Mountain 15-minute quadrangle in Humboldt County, Nevada, were begun during the 1969 summer field season. The objectives of the project are to map the geology of this struct urally complex area at 1:24·,000 scale...
Preliminary photointerpretation map of landslide and other surficial deposits of the Mount Diablo area, Contra Costa and Alameda Counties, California
Tor H. Nilsen
1971, Miscellaneous Field Studies Map 310
The map shows the distribution of landslide and other surficial deposits by presenting the writer's best judgement regarding the origins of the various parts of the present landscape. It is based completely on the interpretation of aerial photographs through a stereoscope, which permits a three-dimentional relief model of the ground...

This bibliography was constructed to be as complete as possible for terminal papers containing new data relative to the geochemical applications of: Common lead U-The-Pb isotopic dating Pb-α Pb210, Pb212, Pb214 No effort was made for completeness of: Annual reports, Yearbooks, etc. Review papers although many are included. Abstracts and theses are omitted....
Analysis of stream-temperature variations in the Upper Delaware River Basin, New York
Owen O. Williams
1971, Water Supply Paper 1999-K
The effect of climatologic conditions and reservoir releases on downstream conditions was determined by means of statistical and graphical analyses of stream-temperature variations measured in the upper Delaware River basin, May-September 1964-67. Climatologic conditions normally increase water temperatures from February through July and decrease them from August through January. Summer...

The Shublik Formation and adjacent strata in northeastern Alaska description, minor elements, depositional environments and diagenesis
Harry Allison Tourtelot, Irvin L. Tailleur
1971, Open-File Report 71-284
The Shublik Formation (Middle and Late Triassic) is widespread in the surface and subsurface of northern Alaska. Four stratigraphic sections along about 70 miles of the front of the northeastern Brooks Range east of the Canning giver were examined and sampled in detail in 1968. These sections and six-step spectrographic...

Detailed geologic and geochemical studies of the four 7 1/2-minute wuadrangles that make up the Edna Mountain 15-minute quadrangle in Humboldt County, Nevada, were begun druring the 1969 summer field season. The objectives of the project are to map the geology of this structurally complex area at 1:24,000 scale and to...
Documentation of the Apollo 14 samples
R. L. Sutton, R. M. Batson, K.B. Larson, J.P. Shafer, R.E. Egglton, G.A. Swann
1971, Open-File Report 71-272
This report was prepared to illustate the locations and lunar orientations of the documented samples returned by Apollo 14. It supersedes U.S. Geological Survey Interagency Report No. 27 (Swann et al., 1971a). Some of the illustrations are taken from the Preliminary Science Report ("Ninety-day report") submitted to the National Aeronautics...
Transmission of digital data
Charles R. Showen
1971, Open-File Report 72-347
The Geological Survey, Water Resources Division, established a pilot project to evaluate equipment that would transmit date recorded on 16-channel paper tapes over voice-grade telephone lines from field offices to the Washington, D.C., Automatic Data Processing Unit (A.D.P. Unit). Such equipment would allow computer-processed data for current-purpose hydrologic data stations...
Al Kushaymiyah as a target for a Colorado-type molybdenite deposit
P. K. Theobald
1971, Open-File Report 71-281
The granitic complex in the vicinity of Al Kushaymiyah was singled out by Whitlow (19,69, 1969a, 1971), as one of the most promising areas for exploration in the Southern Wajd quadrangle (Jackson and others, 1962). He noted in particular the intensity of shattering and silicification of these potassium-rich granites, and...
Distribution of copper, lead, zinc, mercury, and arsenic in the surface sediments off the coast of northwestern Alaska
Peter Barnes, Kam Wo Leong
1971, Miscellaneous Field Studies Map 316
Increasing interest in potentially harmful substances utilized and discarded by man has raised question about the normal distribution of chemical elements in the natural environment. This interest prompted a baseline study of a pristine region off the northern coast of Alaska. Information was gathered on currents, water clarity, nutrients, temperature...

1971, Water Supply Paper 1866-A
The floods of December 1964 and January 1965 in the Far Western States were extreme; in many areas, the greatest in the history of recorded streamflow and substantially greater than those of December 1955. An unusually large area--Oregon, most of Idaho, northern California, southern Washington, and small areas in western...
