Hydrology of three sinkhole basins in southwestern Seminole County, Florida
Warren Anderson, G.H. Hughes
1975, Open-File Report 75-27
The southwestern part of Seminole County--in east-central Florida-is characterized by sinkholes formed by the subsidence of surficial deposits into solution cavities in the underlying limestone deposits. The area includes three sinkhole basins created by such subsidence: Cranes Roost, Palm Springs, and Grace Lake.Cranes Roost basin (drainage area, 5.02 square miles)...
Origin and significance of natural gases of Montana
Dudley D. Rice
1975, Open-File Report 75-188
About two years ago, I was assigned to a project to evaluate the hydrocarbon potential of the Cretaceous system of the northern Rocky Mountains; namely, in Montana, North Dakota, and South Dakota. I had no problem identifying potential traps; both structural and stratigraphic, but recognized the fact that most of...
Configuration of water table and distribution of downward leakage to the Prairie du Chien-Jordan Aquifer in the Minneapolis-Saint Paul metropolitan area, Minnesota
Dana C. Larson-Higdem, S. P. Larson, Ralph F. Norvitch
1975, Open-File Report 75-342
The configuration of the water table as plotted at a contour interval of 20 feet (6 metres) on quadrangle maps (scale 1:2,500) of the Minneapolis-Saint Paul metropolitan area. Control points used for mapping were water levels in wells, lakes and sloughs, and places where topographic contours cross perennial streams. A computer...
Reconnaissance engineering geology of the Ketchikan area, Alaska, with emphasis on evaluation of earthquake and other geologic hazards
Richard W. Lemke
1975, Open-File Report 75-250
The Alaska earthquake of March 27, 1964, dramatically emphasized the need for engineering geologic studies of urban areas in seismically active regions. A reconnaissance study of the Ketchikan area in southeastern Alaska is part of a program to evaluate earthquake and other geologic hazards in most of the larger Alaska...
Geology and coal resources of the Lakhra coal field, Hyderabad area, Pakistan
M.A. Ghani, Robert Lee Harbour, Edwin R. Landis, William Kebblish
1975, Open-File Report 75-553
The Lakhra coal field is about 20 miles northwest of the ancient city of Hyderabad on the west side of the Indus River Valley in the southern part of Pakistan. The Lailian coal bed in the lower part of the Ranikot Formation under- lies an area of at least 64...
Preliminary report on the use of LANDSAT-1 (ERTS-1) reflectance data in locating alteration zones associated with uranium mineralization near Cameron, Arizona
Charles S. Spirakis, Christopher D. Condit
1975, Open-File Report 75-416
LANDSAT-I (ERTS-I) multispectral reflectance data were used to enhance the detection of alteration around uranium deposits near Cameron, Ariz. The technique involved stretching and ratioing computer-enhanced data from which electronic noise and atmospheric haze had been removed. Using present techniques, the work proves that LANDSAT-I data are useful in detecting...
