Basic ground-water data for the Moscow Basin, Idaho
Emerson Gerald Crosthwaite
1975, Report
The Moscow basin encompasses an area of 65 square miles (170 square kilometres) in Latah County and borders the Idaho Washington State line (fig. 1). The basin is along the eastern edge of the "Palouse Country" where the rolling Palouse hills merge with the low mountains of northern Idaho. It...
A proposed glacial history of the Henrys Lake Basin, Idaho
Irving J. Witkind
1975, Journal of Research of the U.S. Geological Survey (3) 67-76
Deposits of several glaciations from oldest to youngest, pre-Bull Lake, Bull Lake, and Pinedale are in and near the Henrys Lake basin, a northwest-trending hourglass-shaped trough in southeastern Idaho. Glacial deposits of pre-Bull Lake age are represented by till remnants confined mostly to the higher levels of the surrounding mountains....
The Nectarian System, a new lunar time-stratigraphic unit
Desiree Stuart-Alexander, Don E. Wilhelm
1975, Journal of Research of the U.S. Geological Survey (3) 53-58
Geologic mapping of the limbs and far side of the Moon has demonstrated the desirability of subdividing the pre-Imbrian rocks. A convenient datum is the Janssen Formation, the ejecta blanket of the Nectaris basin. A new system, herein named the Nectarian System, extends from the base of the Janssen Formation...
K-Ar age of the Similkameen Batholith and Kruger Alkalic Complex, Washington and British Columbia
K. F. Fox Jr., C.D. Rinehart, J. C. Engels
1975, Journal of Research of the U.S. Geological Survey (3) 39-43
Twelve K-Ar age determinations from the Similkameen batholith and the contiguous Kruger Alkalic Complex, including seven newly reported here, range from 69.9 m.y. to 177.2 m.y. Ages of coexisting hornblende and biotite show discordancies ranging from about 72 m.y. to 106 m.y., with hornblende consistently showing the greater analytical age....
Notes on the origin of Colluma Crater, Bolivia
Sam Rosenblum, Reed J. Anderson
1975, Journal of Research of the U.S. Geological Survey (3) 31-38
Colluma Crater, on the semiarid Altiplano (high plain) of western Bolivia, is an oval structure having overall dimensions of 6.7 km by 6.0 km. The structure has two almost concentric cuestaform rims (the inner rim is 3.6 km by 3.1 km) composed of poorly consolidated clastic sediments that dip outward....
Quantitative determination of dawsonite in Green River Shale by powder-sample X-ray diffraction; effect of grinding
E-an Zen, Jane M. Hammarstrom
1975, Journal of Research of the U.S. Geological Survey (3) 21-30
In an effort to evaluate the method of quantitative analysis by X-ray diffraction as a means of determining dawsonite abundances in Green River" oil shale, we performed a series of grinding experiments. Weighed mixtures of dawsonite + quartz and dawsonite + quartz + shale were ground for preset lengths of...
The megaspore genus Henrisporites from the Cretaceous of Massachusetts
Robert H. Tschudy
1975, Journal of Research of the U.S. Geological Survey (3) 15-20
A new megaspore species belonging to the genus Henrisporites was found in Cretaceous (probably Cenomanian) rocks from Massachusetts. Megaspores of Paxillitriletcs dakotaensis (Hall) Hall and Nicolson were found in the same rocks. This paper discusses the occurrence of these two megaspores in North America and describes Henrisporites angustus n. sp....
Ore grade, metal production, and energy
Norman J. Page, S. C. Creasy
1975, Journal of Research of the U.S. Geological Survey (3) 9-13
 Recent resource estimates have been stimulated by national concern over present and pending shortages of energy and mineral resources. Although some believe that the resource base of a commodity is the total amount in the crust, the energy consumption for mining and milling under present technology suggests that grades of...
Changes in the lake trout population of southern Lake Superior in relation to the fishery, the sea lamprey, and stocking, 1950-70
Richard L. Pycha, George R. King
1975, Technical Report 28
Commercial catch and effort statistics for 1929-70, samples of commercial catches in 1959-62, and records of examinations of all lake trout (Salvelinus namaycush) taken commercially in inshore waters of Michigan and Wisconsin in 1962-70 were the basis for descriptions of changes in the population in 1929-70. Abundance fluctuated cyclically and gradually...
Annual contribution of carbon, nitrogen, and phosphorus by migrant Canada geese to a hardwater lake
Bruce A. Manny, Robert G. Wetzel, W.C. Johnson
1975, International Association of Theoretical and Applied Limnology (19) 949-951
Each year more than 6,000 migrant Canada geese (Branta canadensis interior Todd) rest for 3 to 10 days during the months of March, October, November, and December on Wintergreen Lake, a productive 15 ha (33 acre) hardwater lake in the W. K. Kellogg Bird Sanctuary of Michigan State University in...
Predation by fish on walleye eggs on a spawning reef in western Lake Erie, 1969-71
David R. Wolfert, Wolf-Dieter N. Busch, Carl T. Baker
1975, Ohio Journal of Science (75) 118-125
Nearly 2,000 fish representing 21 species were captured with experimental gillnets on Kelleys Island Shoal during the spawning and incubation periods of walleyes (Stizostedion v. vitreum) in 1969-71. A total of 794 stomachs were examined. Four species contained walleye eggs: yellow perch (Perca flavescens), spottail shiner (Notropis hudsonius), stonecat (Noturus...
