Historic water-level changes and pumpage from the principal aquifers of the Memphis area, Tennessee: 1886-1975
James H. Criner, William Scott Parks
1976, Water-Resources Investigations Report 76-67
The Memphis Sand ("500-foot" sand) supplies about 95 percent of the water used in the Memphis area for municipal and industrial purposes. In general, pumpage has increased at an irregular rate since the completion of the first well to this aquifer in 1886. These withdrawals are responsible for an almost...
Preliminary photointerpretation map of landslide and other surficial deposits of the Mount Vaca, Vacaville, and parts of Courtland, Davis, Lake Berryessa, and Woodland 15-minute quadrangles, Napa and Solano counties, California
John D. Sims, Virgil A. Frizzell Jr.
1976, Miscellaneous Field Studies Map 719
This map presents preliminary information about the distribution and general character of landslides and other surficial deposits.  When used in combination with other types of information, such as data on soils, bedrock geology, slopes, seismic response, hydrology, vegetation and climatic variation, it should be easier to arrive at sound decisions...
Geologic map of the Hellas Quadrangle of Mars
D.B. Potter
1976, IMAP 941
The area of MC-28 is centered on the east edge of the Hellas Planitia (Hellas basin and surrounding plains) within densely cratered terrain that covers more than half the surface of Mars (Carr, 1973, fig....
Hydrologic analysis and river-quality data programs
Walter G. Hines, David A. Rickert, Stuart W. McKenzie
1976, Circular 715-D
For nearly half a century the Willamette River in Oregon experienced severe dissolved-oxygen problems related to large loads of organically rich waste waters from industries and municipalities. Since the mid-1950 's dissolved oxygen quality has gradually improved owing to low-flow augmentation, the achievement of basinwide secondary treatment, and the use...
Summary of references to mineral occurrences (other than mineral fuels and construction materials) in the Circle Quadrangle, Alaska
Edward Huntington Cobb
1976, Open-File Report 76-633
These summaries of references are designed to aid in library research on metallic and nonmetallic (other than mineral fuels and construction materials) mineral occurrences in the Circle quadrangle, Alaska. All references to reports of the Geological Survey, to most reports of the U.S. Bureau of Mines, and to most reports...
Geological and geochemical reconnaissance in the central Santander Massif, Departments of Santander and Norte de Santander, Colombia
James George Evans
1976, Open-File Report 77-281
The central Santander Massif is composed of Precambrian Bucaramanga Gneiss and pre-Devonian Silgara Formation intruded by Mesozoic quartz diorite, quartz monzonite, and alaskite and Cretaceous or younger porphyry. Triassic (Bocas Formation), Jurassic (Jordan and Giron Formations).and Cretaceous (Tambor, Rosa Blanca, Paja, Tablazo, Simiti, La Luna, and Umir Formations) sedimentary rocks...
Documentation of programs that compute 1) quasi-static tilts produced by an expanding dislocation loop in an elastic and viscoelastic material, and 2) surface shear stresses, strains, and shear displacements produced by screw dislocations in a vertical slab with modulus contrast
Stuart McHugh
1976, Open-File Report 76-484
The material in this report can be grouped into two categories: 1) programs that compute tilts produced by a vertically oriented expanding rectangular dislocation loop in an elastic or viscoelastic material and 2) programs that compute the shear stresses, strains, and shear displacements in a three-phase half-space (i.e. a half-space...
