Remote detection of geochemical soil anomalies
Frank Cogswell Canney
1970, Open-File Report 70-54
This paper describes a preliminary experiment that was made to compare the spectral reflectance from trees growing in soil over a mineral deposit with reflectance from trees of the same species growing in a nearby unmineralized area. Although the measurements were made on a relatively small number of trees, some...
Chemical quality of Michigan streams
Warren W. Wood
1970, Circular 634
Concentrations of chemical constituents of Michigan streams exhibit regional patterns that are primarily a function of geology and evapotranspiration. However, in some areas waste disposal by municipal and industrial organizations has altered the natural distribution and concentrations of dissolved material. Concentration and areal distribution of chemical constitutents were found to...
Flood profile study, Morgan Creek, Linn County, Iowa
Harlan H. Schwob
1970, Open-File Report 70-295
The purpose of this report is to present the results of a study made for a 35,000-foot reach of Morgan Creek. The report shows profiles computed for a large flood under existing conditions and for a smaller flood for two assumed conditions of encroachment. Flood-plain management can benefit from this...
Water as an urban resource and nuisance
H. E. Thomas, William Joseph Schneider
1970, Circular 601-D
Generally, when people speak of water as a resource, they are considering its good aspects and recognizing that it is essential for life and living. Sometimes or at some places or to some people, the same water may be annoying or unpleasant and thus a nuisance-for example, rain at a...
A strategy for the geologic exploration of the planets
M. H. Carr
1970, Circular 640
The geology of the planets bears directly on three basic aims of lunar and planetary exploration: determination of the origin and evolution of the solor system; determination of the origin and evolution of life; and clarification of the nature of the processes shaping man's terrestrial environment (National Academy of Sciences, 1966...
Preliminary description of cores, chemical analyses of lignite beds, and map showing locations of holes drilled in Grant, Hettinger, Morton, and Stark Counties, North Dakota
H.L. Smith
1970, Open-File Report 70-308
Nineteen exploratory holes were drilled in Grant, Hettinger, Morton, and Stark Counties, N. Dak. (fig. 1), for the U.S. Geological Survey from June 7 to September 15, 1966. This prospect drilling was undertaken to gather data on the thickness, quality, and extent of lignite beds and the lithologic characteristics of...
Geology of the north end of the Ruby Range, southwestern Montana
Russell G. Tysdal
1970, Open-File Report 70-333
This study consists of two parts: stratigraphy and sedimentation, and structure of rocks in the northern one-third of the Ruby Range of southwestern Montana. Detailed studies of Cambrian marine dolomite rocks in the Red Lion Formation and in the upper part of the Pilgrim Limestone resulted in their division into...
Age of the Bedford Shale, Berea Sandstone, and Sunbury Shale in the Appalachian and Michigan basins, Pennsylvania, Ohio, and Michigan
Wallace De Witt Jr.
1970, Bulletin 1294-G
The suggestion by Sanford (1967, p. 994) that the Bedford Shale, Berea Sandstone, and Sunbury Shale of the Michigan basin are of Late Devonian age because these strata contain Hymenozonotriletes lepidophytus Kedo is invalid for these formations in the Appalachian basin, the area of their type localities. Endosporites lacunosus Winslow,...
