Baseline water quality of Iowa's coal region
Larry J. Slack
1979, Open-File Report 79-980
To assist the Iowa Department of Environmental Quality in determining the effects that coal mining and attendant activities will have on the water quality of Iowa streams, the U.S. Geological Survey collected three sets of water-quality samples (representative of high, average, and low streamflow) in the White Breast, English,aand Cedar...
Data compilation of periphyton colonized on artificial substrates placed in the Sacramento and Feather rivers, California, 1975
Linda J. Britton, Rodger F. Ferreira
1979, Open-File Report 79-696
Periphyton was collected from artificial substrates placed in the Sacramento and Feather rivers, California, and analyzed to determine the rate of colonization and succession of periphyton types with time. Samples for determination of water-quality characteristics, especially suspended-sediment concentrations, that might have a direct effect on the growth of periphyton were...
Major-element geochemistry of the Silent Canyon-Black Mountain peralkaline volcanic centers, northwestern Nevada Test Site: applications to an assessment of renewed volcanism
Bruce M. Crowe, Kenneth A. Sargent
1979, Open-File Report 79-926
The Silent Canyon and Black Mountain volcanic centers are located in the northern part of the Nevada Test Site. The Silent Canyon volcanic center is a buried cauldron complex of Miocene age (13-15 m.y.). Black Mountain volcanic center is an elliptical-shaped cauldron complex of late Miocene age.

Land snails from the Paleozoic of North America are known from the coal fields of eastern Canada, from the Dunkard basin west of the Allegheny Mountains, and from the western margin of the Illinois basin. The earliest finds were made about 125 years ago; essentially no new information has been...
Telluric profile and location map for the Broadwater Hot Springs area, Montana
Karen R. Christopherson, R. Michael Senterfit, Vernon Lewis, Moutaz Dalati
1979, Open-File Report 79-1670
A telluric profile (E-field ratio telluric method) was made in the vicinity of the Broadwater Hot Springs, Montana to help assess the geothermal potential of the area. The method and equipment used is similar to that described by Beyer (1977). For this survey the recording bandwidth was 0.025 Hz centered...
