Potential development and recharge of ground water in Mill Creek Valley, Butler and Hamilton Counties, Ohio, based on analog model analysis
Richard E. Fidler
1971, Water Supply Paper 1893
Mill Creek valley is part of the greater Cincinnati industrial area in southwestern Ohio. In 1964, nearly 30 percent of the water supply in the study area of about 27 square miles was obtained from wells in the glacial-outwash aquifer underlying the valley. Ground-water demand has increased steadily since the...
Ground water for irrigation near Lake Emily, Pope County, west-central Minnesota
Wayne A. Van Voast
1971, Water Supply Paper 1899-J
In the Lake Emily area, thickness of the glacial drift ranges from about 200 feet to more than 400 feet. Within the drift are sand and gravel aquifers, some of which can yield adequate water supplies for irrigation. Outwash, as much as 60 feet thick, lies at the surface. The...
Ground water for irrigation in the Brooten-Belgrade area, west-central Minnesota
Wayne A. Van Voast
1971, Water Supply Paper 1899-E
Water for irrigation is needed to improve crop yields from sandy soils in the Brooten-Belgrade area. Ground-water supplies of sufficient quantity and suitable quality for irrigation are available in much of the area. Quaternary glacial drift, as much as 300 feet thick, is underlain by Precambrian crystalline rocks and possibly by...
Linear combination reading program for capture gamma rays
Allan B. Tanner
1971, Open-File Report 71-277
This program computes a weighting function, Qj, which gives a scalar output value of unity when applied to the spectrum of a desired element and a minimum value (considering statistics) when applied to spectra of materials not containing the desired element. Intermediate values are obtained for materials containing the desired...
Transmission of digital data
Charles R. Showen
1971, Open-File Report 72-347
The Geological Survey, Water Resources Division, established a pilot project to evaluate equipment that would transmit date recorded on 16-channel paper tapes over voice-grade telephone lines from field offices to the Washington, D.C., Automatic Data Processing Unit (A.D.P. Unit). Such equipment would allow computer-processed data for current-purpose hydrologic data stations...
Al Kushaymiyah as a target for a Colorado-type molybdenite deposit
P. K. Theobald
1971, Open-File Report 71-281
The granitic complex in the vicinity of Al Kushaymiyah was singled out by Whitlow (19,69, 1969a, 1971), as one of the most promising areas for exploration in the Southern Wajd quadrangle (Jackson and others, 1962). He noted in particular the intensity of shattering and silicification of these potassium-rich granites, and...
The Shublik Formation and adjacent strata in northeastern Alaska description, minor elements, depositional environments and diagenesis
Harry Allison Tourtelot, Irvin L. Tailleur
1971, Open-File Report 71-284
The Shublik Formation (Middle and Late Triassic) is widespread in the surface and subsurface of northern Alaska. Four stratigraphic sections along about 70 miles of the front of the northeastern Brooks Range east of the Canning giver were examined and sampled in detail in 1968. These sections and six-step spectrographic...
The drainage and glacial history of the Still River Valley, southwestern Connecticut
Woodrow B. Thompson
1971, Open-File Report 71-283
The Still River is located in southwestern Connecticut. From its origin on the New York border, it passes through Danbury and flows northward to its junction with the Housatonic River in New Milford. Interpretation of the Still River's history is based on its surficial geology and bedrock topography. High bedrock...
