Field trip guidebook to the hydrogeology of the Rock-Fox River basin of Southeastern Wisconsin
C. L. R. Holt Jr., R. D. Cotter, J. H. Green, P. G. Olcott
1970, Wisconsin Geological & Natural History Survey Information Circular 17
On this trip we will examine some hydrogeologic characteristics of glacial features and emphasize ground-water management within the Rock-Fox River basin. Field stops will include the hydrogeology of a classical glacial terrane--the Kettle moraine--and the management of ground-water resources for industrial, municipal, agricultural, and fish-culture purposes. Descriptions of the geology,...
A test of flushing procedures to control salt-water intrusion at the W. P. Franklin Dam near Ft. Myers, Florida and The magnitude and extent of salt-water contamination in the Caloosahatchee River between La Belle and Olga, Florida
Durward H. Boggess
1970, Information Circular 62
During low-flow periods, salty water from the tidal part of the Caloosahatchee River moves upstream during boat lockages at the W. P. Franklin Darn near Ft. Myers, Florida, as shown on figure L Salty water enters the lock chamber through openings of the downstream sector gates which separate tidal and...
Statistical summaries of New Jersey streamflow records
Stanley L. Laskowski
1970, New Jersey Division of Water Policy and Supply Water Resources Circular 23
In 1961 the U.S. Geological Survey prepared a report which was published by the State of New Jersey as Water Resources Circular 6, "New Jersey Streamflow Records analyzed with Electronic Computer" by Miller and McCall. Basic discharge data for periods of record through 1958 were analyzed for 59 stream-gaging stations...
A computer program to trace seismic ray distribution in complex two-dimensional geological models
Nazieh K. Yacoub, James H. Scott
1970, Report
A computer program has been developed to trace seismic rays and their amplitudes and energies through complex two-dimensional geological models, for which boundaries between elastic units are defined by a series of digitized X-, Y-coordinate values. Input data for the program includes problem identification, control parameters, model coordinates and elastic...
Bibliography of the lunar surface
Jacquelyn H. Freeberg
1970, Report
The term "surface" in this bibliography is defined to include landforms and surface materials and the nature of, and processes responsible for, their physical characteristics. References are divided into two listings: (1) Surface features and materials; and (2) Telescopic observations. The former is accompanied by a subject index, the latter...
Remote detection of geochemical soil anomalies
F. C. Canney
1970, Conference Paper, Proceedings of the second seminar on geochemical prospecting methods and techniques (Mineral Resources Development Series No. 38)
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...
Aeromagnetic and gravity investigations of the Coastal Area and Continental Shelf of Liberia, West Africa, and their relation to continental drift
John C. Behrendt, Cletus S. Wotorson
1970, GSA Bulletin (81) 3563-3574
An aeromagnetic survey has shown the existence of several basins in which magnetic basement depths are greater than 5 km on the continental shelf off Liberia. Magnetic diabase of 176 to 192 m.y. (Jurassic) in age intruding the Paleozoic (?) rocks and overlain by younger rocks onshore requires the distinction...
Uranium ore rolls in the United States
E.N. Harshman
1970, Conference Paper, Uranium exploration geology: Proceedings of a panel, Vienna, 13-17 April 1970
About 40% of the uranium ore reserves in the United States, minable at $8 per pound of contained U3O8, are in roll-type deposits in the State of Wyoming. The host rocks are arkosic sandstones, deposited in intermontane basins under fluvial conditions, and derived from the granitic cores of mountain ranges...
Preliminary geologic investigation of the Apollo 12 landing site: Part B: photometric and polarimetric properties of the lunar regolith
H. E. Holt, J. J. Rennilson
1970, Book chapter, Apollo 12 preliminary science report (NASA SP-235)
Several special, as well as general, photometric and polarimetric studies of the lunar regolith in the vicinity of the Apollo 12 landing site have been undertaken by means of the black-and-white photographs obtained on the geologic traverse during the second extravehicular activity (EVA) period....
Geology and ground water resources, Williams County, North Dakota
Theodore F. Freers, C. A. Armstrong
1970, North Dakota Geological Survey Bulletin 48
Williams County, in northwestern North Dakota, is located near the center of the structural and sedimentary Williston basin. The preglacial sedimentary formations beneath the county are as much as 14,828 feet thick. Their beds dip generally to the south except along the flanks of the north-south striking Nesson anticline in...
Geology and ground water resources of Wells County, North Dakota
John P. Binemie, George A. Falgle, Ronald J. Bred, John R. Reid, Frank Buturla Jr.
1970, Bulletin 51
Wells County is in east-central North Dakota on the eastern flank of the Williston Basin. It is underlain by 4000 to 6000 feet of Paleozoic and Mesozoic rocks that dip gently to the west. The uppermost Cretaceous rocks, the Hell Creek, Fox Hills and Pierre Formations, lie directly beneath the...
