Gold in meteorites and in the earth's crust
Robert Sprague Jones
1968, Circular 603
The reported gold contents of meteorites range from 0.0003 to 8.74 parts per million. Gold is siderophilic, and the greatest amounts in meteorites are in the iron phases. Estimates ,of the gold content of the earth's crust are in the range of 0.001 to 0.006 parts per million....
Geological Survey research 1968, Chapter D
Water Resources Division, U.S. Geological Survey
1968, Professional Paper 600-D
This collection of 48 short papers is the third published chapter of "Geological Survey Research 1968." The papers report on scientific and economic results of current work by members of the Geologic and Water Resources Divisions of the U.S. Geological Survey....
Color photographs for water resources studies
William J. Schneider
1968, Photogrammetric Engineering (34) 257-262
Air-photo interpretation is very well suited to water resources studies where limited observations of hydrologic data must be extended to regional characteristics for large areas. It is also useful in monitoring the hydrologic regimen of an area to detect possible changes. Color aerial photography is generally superior to black-and-white photography...
Geological interpretation of a Gemini photo
William R. Hemphill, Walter Danilchik
1968, Photogrammetric Engineering (34) 150-154
Study of the Gemini V photograph of the Salt Range and Potwar Plateau, West Pakistan, indicates that small-scale orbital photographs permit recognition of the regional continuity of some geologic features, particularly faults and folds that could he easily overlooked on conventional air photographs of larger scale. Some stratigraphic relationships can...
Evaporation study at Warm Springs Reservoir, Oregon
D.D. Harris
1968, Report
The mass transfer-water budget method of computing reservoir evaporation was tested on Warm Springs Reservoir, whose contents and surface area change greatly from early spring to late summer. The mass-transfer coefficient computed for the reservoir is two to three times greater than expected and results in a computed evaporation much...
