Compilation of mean annual suspended-sediment yields for selected streams draining basins within and adjacent to coal fields in the eastern United States
R.E. Hickman
1989, Open-File Report 88-80
Mean annual suspended-sediment yields are listed for 481 selected stations on streams draining basins within and adjacent to the coal fields of the Eastern Coal Province and the eastern region of the Interior Coal Province of the Eastern United States. The drainage basin of each of these stations has an...
Preliminary analysis of the shallow ground-water system in the vicinity of the Grand Calumet River/Indiana Harbor Canal, northwestern Indiana
Lee R. Watson, R. J. Shedlock, K. J. Banaszak, L. D. Arihood, P. K. Doss
1989, Open-File Report 88-492
The shallow groundwater system in the vicinity of the Grand Calumet River-Indiana Harbor Canal, Indiana was analyzed from June 1985 to May 1986. This analysis was done to obtain detailed information about the physical characteristics of the Calumet aquifer and the shallow groundwater flow system. 36 shallow wells were installed...
Geology and water resources of Owens Valley, California
Kenneth J. Hollett, W.R. Danskin, W. F. McCaffrey, C.L. Walti
1989, Open-File Report 88-715
Owens Valley, a long, narrow valley located along the east flank of the Sierra Nevada in east-central California, is the main source of water for the city of Los Angeles. The city diverts most of the surface water in the valley into the Owens River-Los Angeles Aqueduct system, which transports...
Variable-density ground-water flow and paleohydrology in the Waste Isolation Pilot Plant (WIPP) region, southeastern New Mexico
P. B. Davies
1989, Open-File Report 88-490
Variable-density groundwater flow was studied near the Waste Isolation Pilot Plant in southeastern New Mexico. An analysis of the relative magnitude of pressure-related and density-related flow-driving forces indicates that density-related gravity effects are not significant at the plant and to the west but are significant in areas to the north,...
Hydrogeology of the western part of the Salt River Valley area, Maricopa County, Arizona
James G. Brown, D. R. Pool
1989, Water-Resources Investigations Report 88-4202
The Salt River Valley is a major population and agricultural center of more than 3,000 mi2 in central Arizona (fig. 1). The western part of the Salt River Valley area (area of this report) covers about 1,500 mi2. The Phoenix metropolitan area with a population of more than 1.6 million...
Vertical surface displacements along a part of the Newport-Inglewood zone of folds and faults, Los Angeles and Orange Counties, California
Robert O. Castle, Jane M. Buchanan-Banks
1989, Miscellaneous Field Studies Map 2088
During the past half century, the onshore section of the Newport- Inglewood zone of folds and faults between the Dominguez oil field and Corona del Mar (fig. 1) has been repeatedly leveled to geodetic standards. These essentially fortuitous surveys are unrelated to either the tectonic framework or the urbanization...
Distribution, facies, ages, and proposed tectonic associations of regionally metamorphosed rocks in northern Alaska
Cynthia Dusel-Bacon, William Peters Brosge, Alison B. Till, Elizabeth O. Doyle, Charles F. Mayfield, Hillard N. Reiser, Thomas P. Miller
1989, Professional Paper 1497-A
Approximately half of the exposed bedrock in northern Alaska has been regionally metamorphosed. The most widespread metamorphic episode that affected northern Alaska occurred under low-grade, initially high-pressure (blueschist-facies) conditions during Mesozoic time. This episode is thought to have been related to the obduction of one or more oceanic terranes onto...
Geologic map of the Latir Volcanic Field and adjacent areas, northern New Mexico
P. W. Lipman, J. C. Reed Jr.
1989, IMAP 1907
This map was first published as a printed edition in 1989. The geologic data have now been captured digitally and are presented here along with images of the printed map sheet and component parts as PDF files. This map encompasses all or parts of ten 7.5 minute quadrangles in the Taos...
Summary and interpretation of geochemical maps for stream sediment and heavy mineral concentrate samples, Mount Hayes Quadrangle, eastern Alaska Range, Alaska
Gary C. Curtin, Richard B. Tripp, Warren J. Nokleberg
1989, Miscellaneous Field Studies Map 1996-B
This report and accompanying maps summarize the results of geochemical exploration studies in the Mount Hayes quadrangle, Alaska. This is one of a series of maps and reports on the geological, geochemical, and geophysical studies of the quadrangle prepared as part of the Alaskan Mineral Resource Assessment Program (AMRAP) of...
Depositional environments of the Upper Triassic Chinle Formation in the eastern San Juan Basin and vicinity, New Mexico. Trace fossils and mollusks from the upper member of the Wanakah Formation, Chama Basin, New Mexico; evidence for a lacustrine origin. Stratigraphy, facies, and paleotectonic history of Mississippian rocks in the San Juan Basin of northwestern New Mexico and adjacent areas
Russell F. Dubiel, Jennie L. Ridgley, Augustus K. Armstrong, Lee D. Holcomb
