Hot, deep origin of petroleum: deep basin evidence and application
Leigh C. Price
1978, Open-File Report 78-1020
Use of the model of a hot deep origin of oil places rigid constraints on the migration and entrapment of crude oil. Specifically, oil originating from depth migrates vertically up faults and is emplaced in traps at shallower depths. Review of petroleum-producing basins worldwide shows oil occurrence in these basins...

Hydrologic reconnaissance of the Yampa River during low flow, Dinosaur National Monument, northwestern Colorado
Timothy Doak Steele, Dennis A. Wentz, James W. Warner
1978, Open-File Report 78-226
A hydrologic reconnaissance of a 74-kilometer reach of the Yampa River in Dinosaur National Monument was made during low flow in mid-August 1976. Stream discharge, which was measured along this reach every 16 to 24 kilometers, ranged from 9.4 to 10.6 cubic meters per second. Variations in streamflow were explained,...

William H. Langer, Stephen F. Obermeier
1978, Open-File Report 78-779
Landsliding is a common problem in eastern Fairfax County, an area underlain by Potomac Group (Lower Cretaceous) Coastal Plain deposits of silt and clay interbedded and interfingered with sand and gravel. The slides commonly are present in clay and silt that, on the basis of laboratory tests, appear to be...

George J. Neuerburg, H. N. Barton, J.R. Watterson, E. P. Welsch
1978, Open-File Report 78-383
Paired rock and soil samples were collected at widely spaced locations in large segments of the porphyry-metal systems of the Montezuma district in central Colorado and of a northwestward extension of the Summitville district into Crater Creek in southern Colorado. The paired samples do not covary closely enough for one...

Low-cost computer classification of land cover in the Portland area, Oregon, by signature extension techniques
Leonard Gaydos
1978, Open-File Report 78-186
Computer-aided techniques for interpreting multispectral data acquired by Landsat offer economies in the mapping of land cover. Even so, the actual establishment of the statistical classes, or "signatures," is one of the relatively more costly operations involved. Analysts have therefore been seeking cost-saving signature extension techniques that would accept training...
