Channels and valleys on Mars
Mars Channel Working Group
1983, GSA Bulletin (94) 1035-1054
The discovery of channels, valleys, and related features of aqueous origin on Mars is of profound importance in comparative planetology. Models of the evolution of planetary surfaces and atmospheres must be reconciled with the diversity, abundance, and origins of channels and valleys on Mars. The term “channel” is properly restricted...
Atmospheric deposition: Sample handling, storage, and analytical procedures for chemical characterization of event-based samples in North Dakota
R. L. Houghton, Mary E. Berger, Nancy Zander, Sandra K. Dutchek
1983, Water-Resources Investigations Report 83-4205
The North Dakota atmospheric-deposition network uses HASL-type collectors to sample wet and dry deposition on an event basis for analysis of 8 principal mineral, 3 nutrient, and 15 trace constituents. Comparison of the compositions of wet deposition collected in adjacent collectors sampled on weekly and event bases indicates that weekly...
Eolian sand bodies of the world
E. D. McKee
1983, Developments in Sedimentology (38) 1-25
This chapter examines the eolian sand bodies of the world. Analyses regarding grain size and sorting distribution at Great Sand Dunes indicate that the higher dunes contain much more fine-grained sand and much less medium-grained sand than do the lower dunes, and, in addition, they are definitely better sorted. Cross-stratification...

A tale of two plutons: petrographic and mineralogic constraints on the petrogenesis of the Red Lake and Eagle Peak plutons, central Sierra Nevada, California
J.H. Noyes, D. R. Wones, F.A. Frey
1983, Journal of Geology (91) 353-379
The two plutons are similar in age (K/Ar, 87-89 m.y.) and range in composition from granodiorite to granite. The Red Lake pluton is equigranular, has a locally greisened marginal zone, and shows only minor mineralogical and chemical zoning, whereas the Eagle Peak pluton is mineralogically, compositionally and texturally zoned, with...
Anaerobic oxalate degradation: Widespread natural occurrence in aquatic sediments
Richard L. Smith, Ronald S. Oremland
1983, Applied and Environmental Microbiology (46) 106-113
Significant concentrations of oxalate (dissolved plus particulate) were present in sediments taken from a diversity of aquatic environments, ranging from 0.1 to 0.7 mmol/liter of sediment. These included pelagic and littoral sediments from two freshwater lakes (Searsville Lake, Calif., and Lake Tahoe, Calif.), a hypersaline, meromictic,...
Hydrology of the Ferron Sandstone aquifer and effects of proposed surface-coal mining in Castle Valley, Utah, with a section on stratigraphy and a section on leaching of overburden
Gregory C. Lines, Daniel J. Morrissey, Thomas A. Ryer, Richard H. Fuller
1983, Water Supply Paper 2195
Coal in the Ferron Sandstone Member of the Mancos Shale of Cretaceous age has traditionally been mined by underground techniques in the Emery Coal Field in the southern end of Castle Valley in east-central Utah. However, approximately 99 million tons are recoverable by surface mining. Ground water in the Ferron...
Cenozoic structural history of selected areas in the eastern Great Basin, Nevada-Utah
R. Ernest Anderson
1983, Open-File Report 83-504
The Confusion Range structural trough (CRST) of west-central Utah predates the Oligocene rocks that are exposed along it. The northern part of the axial region of the CRST is complicated by structures that include reverse faults and associated folds, a large-amplitude mushroom fold, and belts of sharply flexed to overturned...
Hydrologic and geomorphic studies of the Platte River basin
Water Resources Division, U.S. Geological Survey
1983, Professional Paper 1277
The channels of the Platte River and its major tributaries, the South Platte and North Platte Rivers in Colorado, Wyoming, and Nebraska, have undergone major changes in hydrologic regime and morphology since about 1860, when the water resources of the basin began to be developed for agricultural, municipal, and industrial...
