Notes on some experiments on the application of subtractive compensation to USGS seismic magnetic tape recording and playback systems
Jerry P. Eaton
1975, Open-File Report 75-663
The purpose of these experiments is to lay the groundwork for the implementation of subtractive compensation of the USGS seismic network tape playbacks utilizing the Develco model 6203 discriminators at a x1 playback speed. Although the Develco discriminators were designed for this application and a matching Develco compensation discriminator was...
Geologic map of the Mount Abbot quadrangle, central Sierra Nevada, California
John P. Lockwood, Phillip A. Lydon
1975, Geologic Quadrangle 1155
The Mount Abbot quadrangle comprises about 240 square miles of high montane to alpine terrain straddling the Sierra Nevada crest between Fresno and Bishop, California.

Experimental results of atomic absorption analyses for indium and thallium in 803 nonmagnetic concentrates from Alaska
William C. Overstreet, George L. Crenshaw, Arthur E. Hubert, Sam Rosenblum, Ricke J. Smith
1975, Open-File Report 75-253
The development in the U.S. Geological Survey of rapid methods for the determination by atomic absorption spectrophotometry of indium and thallium at limits of detection as low as 0.2 ppm each in geologic materials affords great advantages over spectrographic methods in studies concerned with values at or near the crustal...
Ground-water resources of Greeley and Wichita counties, Western Kansas
Steven E. Slagle, Edward C. Weakly
1975, Open-File Report 75-557
Unconsolidated deposits of sand, silt, clay, and gravel compose the principal aquifer in Greeley and Wichita Counties. The deposits are as much as 300 feet (91 m) 2/ thick, of which as much as 145 feet (44 m) is saturated.In 1972, there were about 1,040 large-capacity wells--yielding 100 gallons per...
A water-quality assessment of the Burnham Creek Watershed, Polk County, Minnesota
M.R. Have
1975, Open-File Report 75-647
A water-quality assessment of the Burnham Creek watershed, Polk County, Minn., was made in May 1975. Surface waters were calcium magnesium bicarbonate types with 0.11 mg/liter or less of nitrite plus nitrate nitrogen and 0.10 mg/liter or less of total phosphorous. Fecal coliform bacteria concentrations were between 3 and 720...
