Preliminary geologic interpretation of aeromagnetic data in the Nixon Fork district, Alaska
Lennart A. Anderson, Bruce L. Reed, Gordon R. Johnson
1969, Open-File Report 69-9
An aeromagnetic map covering 480 square miles was compiled for the Nixon Fork district, which is located approximately 35 miles northeast of McGrath, Alaska. The survey was flown in search of concealed intrusive rocks which may have produced contact metamorphic deposits in limestone similar to the known lode deposits which...
Tectonics of the March 27, 1964, Alaska earthquake
George Plafker
1969, Professional Paper 543-I
The March 27, 1964, earthquake was accomp anied by crustal deformation-including warping, horizontal distortion, and faulting-over probably more than 110,000 square miles of land and sea bottom in south-central Alaska. Regional uplift and subsidence occurred mainly in two nearly parallel elongate zones, together about 600 miles long and as much...
Floods in Gravois Creek Basin, St. Louis County, Missouri
L.D. Hauth, D.W. Spencer
1969, Open-File Report 69-122
The rapid growth of suburban St. Louis presents problems in the social and economic development of flood plains within the area. The U.S. Geological Survey, in cooperation with the Metropolitan St. Louis Sewer District, is conducting a study of the hydrology of five major drainage basins within the area of...
Gold anomalies and magnetometer profile data, Ester Dome area, Fairbanks district, Alaska
D. L. Stevens, Robert B. Forbes, D. B. Hawkins
1969, Open-File Report 69-266
Gold analysis of grab and auger samples of bedrock taken along the new Ester Dome Road reveals that this road cuts several mineralized zones characterized by anomalous concentrations of gold. The results of a magnetometer traverse along this road indicate that the negative magnetic anomalies along the traverse may be...
Chemical quality of surface water in the Umpqua River Basin, Oregon
D. A. Curtiss
1969, Open-File Report 69-67
In July 1967, the U.S. Geological Survey, in cooperation with Douglas County, began a 2-year study of the chemical quality of surface water in the Umpqua River basin. The purpose of this report is to present an interpretive summary of the data collected, which will provide answers to the following...
Recent surface movements in the Baldwin Hills, Los Angeles County, California
Robert O. Castle, R. F. Yerkes
1969, Open-File Report 69-36
The Baldwin Hills are located in the northwest part of the densely populated Los Angeles basin. They comprise one of several groups of isolated hills that extend along the northwest-trending Newport-Inglewood zone of folds and faults, a structural lineament identified with a series of very productive oil fields. In addition...
Surveying the earth's resources from space
William T. Pecora
1969, TRW Space Log (9) 2-15
During the past 4 years, scientists of the Geological Survey, in cooperation with NASA, have been investigating the feasibility and practicality of using remote-sensor data collected during conventional aircraft flights. This work is aimed at developing techniques for gathering facts about the earth's natural resources from satellites carrying sophisticated remote-sensing...
Satellite imagery of the earth
P.M. Merifield, J. Cronin, L.L. Foshee, S.J. Gawarecki, J.T. Neal, R. E. Stevenson, R.O. Stone, R.S. Williams Jr.
1969, Photogrammetric Engineering (35) 654-668
Photography of the Earth from spacecraft has application to both atmospheric and Earth sciences. Gemini and Apollo photographs have furnished information on sea surface roughness, areas of potential upwelling and oceanic current systems. Regional geologic structures and geomorphologic features are also recorded in orbital photographs. Infrared satellite imagery provides meteorological...
The geographic applications program of the U. S. Geological Survey
Arch C. Gerlach
1969, Photogrammetric Engineering (35) 58-60
The fundamental objective of modern Geography is to improve man's level of living through a better understanding of man-environment inter actions. Related goals of the USGS program for applications of remote sensor data to Geographical research are: (1) the analysis and improvement of land use, with special emphasis on urban...
Finney County Basic Data
W.R. Meyer, E. D. Gutentag, D.H. Lobmeyer
1969, Report
This open-file report contains basic data on measurements and chemical analyses of ground water, logs of test holes, and summary information on selected logs for Finney County, Kans....
Ground-water data as of 1967, Central Coastal Subregion, California
J. S. Bader
1969, Report
Most usable ground water in the predominantly mountainous Central Coastal Subregion occurs in alluvium-filled valleys and coastal plains and in deeper aquifers of Quaternary and Tertiary age. The intervening mountainous areas are underlain by consolidated sedimentary, igneous, and metamorphic rocks, mainly of Mesozoic age. These older rocks contain only small...
Distribution of oxygen and carbon isotopes in fossils of late cretaceous age, western interior region of North America
H. A. Tourtelot, R.O. Rye
1969, Geological Society of America Bulletin (80) 1903-1922
The oxygen isotope composition of both calcite and aragonite of the pelecypod Inoceramus is lighter than the composition of the aragonite of associated baculites and other cephalopods from the western interior region, the Gulf and Atlantic Coastal Plains, parts of Canada, and West Greenland. This difference cannot be explained by...
