Analysis of Shublik Formation rocks from Mt. Michelson quadrangle, Alaska
Robert L. Detterman
1970, Open-File Report 70-101
Analysis of 88 samples from the Shublik formation on Fire Creek, Mt. Michelson Quadrangle, Alaska, are presented in tabular form. The results include the determination of elements by semiquantitative spectrographic analysis, phosphate by X-ray fluorescence, carbon dioxide by acid decomposable carbonate, total carbon by induction furnace, carbonate carbon by conversion...
Feasibility of surveying pesticide coverage with airborne fluorometer
George Eimert Stoertz, William R. Hemphill
1970, Open-File Report 70-315
Response of a Fraunhofer line discriminator (FLD) to varying distributions of granulated corncobs stained with varying concentrations of Rhodamine WT dye was tested on the ground and from an H-19 helicopter. By design the instrument detected fluorescence specifically at the sodium D2 Fraunhofer line (5890 angstroms). The granules are used...
Geologic, geochemical, and geophysical investigations in the northern part of the Gilmore mining district, Lemhi County, Idaho
Edward Thompson Ruppel, K. C. Watts, Donald L. Peterson
1970, Open-File Report 70-282
Geologic, geochemical, and geophysical investigations in the northern part of the Gilmore (Texas) mining district, Lemhi County, Idaho, indicate an area of anomalous concentrations of lead and silver in glacial deposits. These deposits overlie the probable extensions of the main veins as them are projected northward from the central part...
Digital computer terrain mapping from multispectral data, and evaluation of proposed Earth Resources Technology Satellite (ERTS) data channels, Yellowstone National Park preliminary report
Harry Wynn Smedes, K. L. Pierce, Marc G. Tanguay, R.M. Hoffer
1970, Open-File Report 70-307
Digital computer processing of 12 wavelength bands of visible and reflective infrared scanner data has resulted in successful automatic computer mapping of eight terrain units in a Yellowstone National Park test site. Target areas in the scene were selected for training the computer. Statistical parameters of radiance such as mean,...
Geologic studies of Yellowstone National Park imagery using an electronic image enhancement system
Harry Wynn Smedes
1970, Open-File Report 70-306
This report describes the image enhancement system developed by the Philco-Ford Corporation; the kinds of enhancement attained; the results obtained from various kinds of remote-sensing imagery (mainly black and white multiband, color, color infrared, thermal infrared, and side-looking K-band radar) of parts of Yellowstone National Park; and possible additional fields...
A proposed streamflow-data program for North Dakota
O.A. Crosby
1970, Open-File Report 70-91
An evaluation of the streamflow data available in North Dakota was made to provide guidelines for planning future programs. The basic steps in the evaluation procedure were (1) definition of the long-term goals of the streamflow data program in quantitative form, (2) examination and analysis of all available data to...
Hydraulic testing and sampling of hole Ue-1 in central Nevada
G.A. Dinwiddie
1970, Open-File Report 70-103
Hydraulic testing and sampling of hole Ue-1 began on January 31, 1967, and ended on February 13, 1967. Depth intervals tested and sampled were: zone 1, 1,710 feet to total depth; zone 2, 1,508 to 1,706 feet; zone 3, 1,266 to 1,464 feet; zone 4, 788 to 986 feet; and...
A proposed streamflow data program for Oklahoma
J.D. Bohn, G. L. Hoffman
1970, Open-File Report 70-32
An evaluation of the streamflow data available in Oklahoma has been made to provide guidelines for planning future data-collection programs. The basic steps in the evaluation procedure were (1) definition of the long-terms goals of the streamflow-data program in quantitative form, (2) examination and analysis of streamflow data to determine...
Geology of Precambrian rocks and isotope geochemistry of shear zones in the Big Narrows area, northern Front Range, Colorado
Jeffrey T. Abbott
1970, Open-File Report 70-1
Rocks within the Big Narrows and Poudre Park quadrangles located in the northern Front Range of Colorado are Precambrian metasedimentary and metaigneous schists and gneisses and plutonic igneous rocks. These are locally mantled by extensive late Tertiary and Quaternary fluvial gravels. The southern boundary of the Log Cabin batholith lies...
