Geologic map of the Noachis Quadrangle of Mars
J.E. Peterson
1977, IMAP 910
The Noachis quadrangle is in the ancient cratered highlands of Mars. Craters dominate the surface of the planet in this area; most are of impact origin, some are of...
Late Quaternary depositional history, Holocene sea-level changes, and vertical crustal movement, southern San Francisco Bay, California
Brian F. Atwater, Charles W. Hedel, Edward J. Helley
1977, Professional Paper 1014
Sediments collected for bridge foundation studies at southern San Francisco Bay, Calif., record estuaries that formed during Sangamon (100,000 years ago) and post-Wisconsin (less than 10,000 years ago) high stands of sea level. The estuarine deposits of Sangamon and post-Wisconsin ages are separated by alluvial and eolian deposits and by...
Geologic map of the Iapygia Quadrangle of Mars
G. G. Schaber
1977, IMAP 1020
The Iaygia quadrangle, in the equatorial region of Mars just north of the Hellas basin, is mainly ancient, hilly, and cratered upland terrain. The southern one-third of the quadrangle is dominated by mountains and knobby...
Movement of moisture in the unsaturated zone in a loess-mantled area, southwestern Kansas
Robert C. Prill
1977, Professional Paper 1021
A study of moisture movement associated with ponding near Garden City, Kansas, indicates that loess-manted areas have excellent potential for artificial recharge by water spreading. Infiltration stabilized at rates ranging from 0.7 to 2.2 feet (0.2 to 0.7 meter) per day reflecting changes in hydraulic conductivity of soil horizons. Results...
Characteristics of thin-skinned style of deformation in the southern Appalachians, and potential hydrocarbon traps
Leonard Dorrean Harris, Robert C. Milici
1977, Professional Paper 1018
This paper is an attempt to focus attention on the more important characteristics of the thin-skinned style of deformation in the southern Appalachians by presenting a model to illustrate the regional anatomy and to identify likely structures that need additional investigation as possible prospects for hydrocarbon accumulation. Five distinct changes...
Factors limiting the sensitivity and dynamic range of a seismic system employing analog magnetic tape recording and a seismic amplifier with adjustable gain settings and several output levels
Jerry P. Eaton, John R. Van Schaack
1977, Open-File Report 77-224
In the course of modernizing the low-speed-tape-recorder portable seismic systems and considering the possibilities for the design of a cassette-tape-recorder seismic refraction system, the factors that limit the sensitivity and dynamic range of such systems have been reviewed. These factors will first be stated briefly, and then their influence on...
Geologic map of the west side of the Moon
D. H. Scott, J.F. McCauley, M.N. West
1977, IMAP 1034
The west limb region of the Moon consists of highly cratered terra rising 5 km or more above the mare of Oceanus Procellarum and most of the lunar near...
