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...
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....
Premetamorphic hydrothermal origin of the Tungsten Queen vein, Hamme District, North Carolina, as indicated by mineral textures and minor structures
Michael P. Foose, John F. Slack
1978, Open-File Report 78-427
The Hamme Tungsten district is a 13-km long, 2-km wide, northeast-trending belt located in northern Vance County, North Carolina and southern Mecklenburg County, Virginia (Fig. 1). The district contains the largest quartz-wolframite-type vein deposits in the United States. Over 50 tungsten-bearing veins occur in this area (Espenshade, 1947), from which...
Chemical and biological quality of Lakes Faith, Hope, and Charity at Maitland, Florida, with emphasis on the effects of storm runoff and bulk precipitation, 1971-1974
Neville G. Gaggiani, A. G. Lamonds
1978, Open-File Report 77-491
Located in a closed basin, near Orlands, Fla., Lake Faith, Hope, and Charity cover a combined area of 132 acres and are surrounded by residential, citrus grove and undeveloped areas. All of these areas affect the water quality of the lakes through storm runoff and transport of windborne material. During...
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....
Bibliography of the available data on the solubility of silica in water substance
Robert W. Potter, W.L. Marshall, R.O. Fournier, O.I. Martynova
1978, Open-File Report 78-731
The following bibliography represents the currently available experimental data for the solubility of silica in water substance as a function of temperature and pressure. These references were compiled by the silica subcommittee of Working Group IV at the 1977 meeting of LAPS in Moscow. The data summarized in these references...
Profiles showing potentiometric surfaces and changes in effective stress in aquifers in Harris and Galveston counties, Texas, 1977-78
R.K. Gabrysch
1978, Open-File Report 78-299
These profiles were prepared by the U.S. Geological Survey in cooperation with the Harris-Galveston Counties Coastal Subsidence District and the Texas Department of Water Resources to show the changes in the altitudes of the potentiometric surfaces and, consequently, the changes in effective stress on the framework of the aquifers as...
Geochemical map showing the distribution and abundance of copper in stream sediments in the Seward and Blying Sound quadrangles, Alaska
R. B. Tripp, W.D. Crim, E.F. Cooley, G.W. Day
1978, Miscellaneous Field Studies Map 880-E
Reconnaissance geochemical and mineralogical sampling was done in the Seward and Blying Sound quadrangles during 1975 and 1976 as part of the Alaska Mineral Resources Assessment Program (AMRAP). This map shows the distribution and abundance of copper in stream-sediment samples. Stream-sediment samples were collected at 569 sites from active stream channels...
Water level measurements in 52 shallow boreholes in the San Francisco Bay region
Edward F. Roth
1978, Open-File Report 78-935
Water-level measurements have been read in 52 cased boreholes in the San Francisco bay region. These measurements are compared to water-table depths determined by P-wave velocity. A velocity in excess of 1200 m/s is taken as the depth of the upper surface of the water table. This method works best...
