Determination of platinum and palladium in geological materials by neutron-activation analysis after fire-assay preconcentration
J.J. Rowe, F.O. Simon
1971, Talanta (18) 121-125
Fire-asay preconcentration followed by neutron-activation analysis permits the determination of as little as 0.5 ppM of platinum and 0.5 ppM of palladium on a 20-g sample. Platinum and palladium are separated with carriers and beta-counted. Results for the platinum and palladium content of seven U.S.G.S. standard...
Use of time-lapse photography equipment for hydrologic studies
J.R. Beck
1971, Report
This report describes equipment used for recording hydrologic events photographically on a controlled time scale. Equipment used included a 16-mm (millimeter) motion-picture camera, batteries, and associated intervalometer hardware.Variables that affected operation of the equipment, and which were used to turn the equipment on and off upon demand, were sunlight intensity,...
Aerial photographic reproductions
Water Resources Division, U.S. Geological Survey
1971, Report
Geological Survey vertical aerial photography is obtained primarily for topographic and geologic mapping. Reproductions from this photography are usually satisfactory for general use. Because reproductions are not stocked, but are custom processed for each order, they cannot be returned for credit or refund....
Surface water supply of the United States, 1961-65, Part 13. Snake River basin
1971, Water Supply Paper 1934
This volume is one of a series of 37 reports presenting records of stage, discharge, and content, of streams, lakes, and reservoirs in the United States during the 1961-65 water years. Since 1888, when the U.S. Geological Survey first studied streamflow in relation to problems of irrigation, similar records have been obtained at...

Turbidity and suspended-sediment transport in the Russian River Basin, California
John R. Ritter, William M. Brown III
1971, Open-File Report 72-316
The Russian River in north coastal California has a persistent turbidness, which has reportedly caused a decline in the success of the sports fishermen. As a consequence, the number of sports fishermen angling in the river has declined, and industries dependent on their business have suffered. To determine the source...

Classification of public lands valuable for geothermal steam and associated geothermal resources
Larry H. Godwin, L. B. Haigler, R.L. Rioux, D. E. White, L.J. Muffler, R. G. Wayland
1971, Circular 647
The Organic Act of 1879 (43 U.S.C. 31) that established the U.S. Geological Survey provided, among other things, for the classification of the public lands and for the examination of the geological structure, mineral sources, and products of the national domain. In order to provide uniform executive action in classifying...
