Techniques for the evaluation of surface wind data in terms of eolian sand drift
Steven G. Fryberger
1978, Open-File Report 78-405
The purpose of this report is to summarize briefly techniques presently in use by the U.S. Geological Survey (Denver) to analyze surface wind data in terms of eolian sand drift. These techniques were developed for regional analysis of surface wind directional and energy characteristics in connection with Chapter F "Dune...
K-Ar geochronology of the Survey Pass, Ambler River and Eastern Baird Mountains quadrangles, southwestern Brooks Range, Alaska
Donald L. Turner, R. B. Forbes, C.F. Mayfield
1978, Open-File Report 78-254
We report 76 previously unpublished K-Ar mineral ages from 47 metamorphic and igneous rocks in the southwestern Brooks Range. The pattern of radiometric ages is complex, reflecting the complex geologic history of this area. Local and regional radiometric evidence suggests that the southern Brooks Range schist belt has, at least...
Preliminary geologic report on the Harris Lake area, northeastern Minnesota
M. P. Foose, Roger W. Cooper
1978, Open-File Report 78-385
Intense faulting and fracturing in the Harris Lake area) northeastern Minnesota are documented by detailed field studies. Faults are identified chiefly by the disruption of mappable layers within sequences of plagioclase and plagioclase-olivine cumulates. Most layers grade from olivine-rich bottoms to plagioclase-rich tops and were probably deposited by density currents....
Preliminary hydrologic budget of the sand-and-gravel aquifer under unstressed conditions: with a section on water-quality monitoring, Pensacola, Florida
Henry Trapp Jr.
1978, Water-Resources Investigations Report 77-96
The sand-and-gravel aquifer is the only freshwater aquifer in southern Escambia County, Fla. Problems related to the development of the aquifer include sustained yield, contamination, and saltwater intrusion. A digital model was applied to the sand-and-gravel aquifer in central and southern Escambia County treating the aquifer 's 'main producing zone...
Radioactive anomaly and mineralogy of the lower part of the Tabuk Formation, Al Qassim area, Kingdom of Saudi Arabia
John J. Matzko, V. J. Flanigan, Mustafa Mawad, Ziad Al Kollak, M.I. Naqvi, Abdul Malik Helaby
1978, Open-File Report 78-520
A radioactive anomaly about 10 km long was detected by an airborne survey of the Tabuk Formation, about 75 km west-northwest of Buraydah in northeastern Saudi Arabia. The gamma-spectrometer anomaly is 6 to 10 times higher than background over the adjacent Precambrian shield area and indicates anomalous concentrations of thorium-bearing...
Temperature in streams of New Mexico for the period October 1964 to September 1969
Ralph W. Clement
1978, Water-Resources Investigations Report 78-140
Harmonic equations were developed to describe stream temperatures at 144 sites in New Mexico using periodically observed water temperatures collected from October 1964 through September 1969. The harmonic equations explained at least 80 percent of the variability at 70 of the sites. Standard errors of estimate ranged from 1.3 to...
Hydrologic and geomorphic data from the Piceance Basin, Colorado, 1972-77
Donald G. Frickel
1978, Open-File Report 78-825
This report is a compilation of erosion measurements made at 121 channel sites and 45 hillslope sites during the period 1972-77 in the Piceance basin of northwestern Colorado. The data were collected as part of channel-morphology, sediment-transport, and erosion-rate studies being conducted in conjunction with development of the oil-shale resource...
Radiometric results and areal distribution for granitic samples from the Granite Mountains, Wyoming
John S. Stuckless, Carl M. Bunker, George Van Trump, Charles A Bush
1978, Open-File Report 78-803
Analyses of surface samples from the Granite Mountains, Wyoming, generally agree with the findings from drilling at two different localities. The dominant Precambrian granitic rock type is the biotitic phase of the granite of Lankin Dome. This rock type is characterized by high potassium and anomalously high thorium concentrations, and...
Availability of fresh and slightly saline ground water in the basins of westernmost Texas
Joseph Spencer Gates, W. D. Stanley, H.D. Ackermann
1978, Open-File Report 78-663
Significant quantities of fresh ground water occur in the basin fill of the northern Hueco bolson and lower Mesilla Valley and in the Wildhorse Flat, Michigan Flat, Lobo Flat, and Ryan Flat areas of the Salt Basin; and may occur in Red Light Draw, Presidio bolson, and Green River valley....
Cyclic landsliding at Wrightwood, southern California: A preliminary report
Douglas M. Morton, Russell H. Campbell
1978, Open-File Report 78-1079
Recurring landslide and mudflow events in the Wrightwood area of Southern California are parts of a composite cycle of landslide activity that includes three recognizable stages. The three stages are interdependent, occur in sequence, and are of different duration. Deposits of the first stage--the largest in size--are removed to positions...
