Concentration and mineralogical residence of elements in rich oil shales of the Green River Formation, Piceance Creek Basin, Colorado, and the Uinta Basin, Utah; a preliminary report
George A. Desborough, Janet K. Pitman, Claude Huffman Jr.
1974, Open-File Report 74-77
Ten core samples of two rich oil-shale beds from the Parachute Creek Member of the Eocene Green River Formation, Piceance Creek basin, Colorado, and Uinta Basin, Utah, were analyzed for 34 major, minor, and trace elements. For 23 of these elements, principal mineralogical residence is established or suggested. Such studies...
Catalog of earthquakes along the San Andreas fault system in central California, October-December 1972
R. L. Wesson, F.W. Lester, K.L. Meagher
1974, Open-File Report 74-1122
Numerous small earthquakes occur each day in the coast ranges of Central California. The detailed study of these earthquakes provides a tool for gaining insight into the tectonic and physical processes responsible for the generation of damaging earthquakes. This catalog contains the fundamental parameters for earthquakes located within and adjacent...
Physical and chemical characteristics of Lake Oahe, 1968-69
James H. Selgeby, William E. Jones
1974, Technical Paper 72
The physical and chemical characteristics presented provide a description of Lake Oahe and establish bases for certain characteristics which may alter as the reservoir ages. Water temperatures were strongly influenced by wind-driven currents and water depth. The duration of thermal stratification varied from about 3 wk in the upstream portion...

Evaluation of trawls for monitoring and harvesting fish populations in Lake Oahe, South Dakota
William R. Nelson, Marvin S. Boussu
1974, Technical Paper 76
Trawls of various designs and sizes were compared to evaluate their use for monitoring and harvesting fish populations in Lake Oahe. Catches of a 10.7-m semiballoon trawl, selected to monitor changes in the fish populations from 1965 to 1970, showed a downward trend in the abundance of all species, except...
