Cross sections of Lower Ordovician carbonate depositional lithofacies and Mississippi Valley-type zinc-and iron-sulfide mineralization in the Caufield district, east-central part of Harrison 1 degree by 2 degrees Quadrangle, Arkansas and Missouri
Timothy S. Hayes, James R. Palmer, Gary Krizanich
1992, Miscellaneous Field Studies Map 1994-C
As part of the Harrison 1° X 2° CUSMAP study, we examined eight drill cores from the Caulfield district (see index map) in south-central Missouri. This report presents the results of the core study and cross sections and correlation diagrams compiled from the core data (cross sections A-A' and B-B' and...
Limnology of Big Lake, south-central Alaska, 1983-84
Paul F. Woods
1992, Water Supply Paper 2382
The limnological characteristics and trophic state of Big Lake in south-central Alaska were determined from the results of an intensive study during 1983-84. The study was begun in response to concern over the potential for eutrophication of Big Lake, which has experienced substantial residential development and recreational use because of...
Hydrologic data for a study of pre-Illinoian glacial till in Linn County, Iowa, water year 1991
P.R. Bowman
1992, Open-File Report 92-500
Hydrologic data for a study of pre-lllinoian glacial till were collected during the 1991 water year at a site in Linn County, east-central Iowa. A hydrologic-data-collection network, consisting of a meteorological station, 22 observation wells, and a water-quality minimonitor, was installed at the site to investigate the hydraulic properties of...
Ages of rocks in southwestern Washington and northwestern Oregon as indicated by paleontological and isotopic dates
Wendy Adams Niem, Alan R. Niem
1992, Open-File Report 92-344
This report presents a compilation of 1,019 paleontologic dates and 301 isotopic dates of rocks in southwestern Washington and northwestern Oregon. The study area extends from Portland, Oregon (latitude 45°30' N.) to Bellevue, Washington (latitude 47°35' N.) and from the east flank of the Cascade Range (longitude 121°20' W.) to...
Geologic studies in Alaska by the U.S. Geological Survey, 1991
Dwight Culver Bradley, Cynthia Dusel-Bacon, editor(s)
1992, Bulletin 2041
This collection of twenty-one papers continues the annual series of U.S. Geological Survey reports on the geology of Alaska. These contributions, which include full-length Articles and shorter Geologic Notes, are grouped under two broad headings: Mineral Resource Studies (ten papers) and Geologic Framework Studies (eleven papers). Reports on mineral resources...
Text and References To Accompany "Map Showing the Thickness and Character of Quaternary Sediments in the Glaciated United States East of the Rocky Mountains"
David R. Soller
1992, Bulletin 1921
A 1:1,000,000-scale map of Quaternary deposits has been compiled for the glaciated area of the United States east of the Rocky Mountains (that is, the area covered by the Laurentide ice sheets). Parts of southern Ontario, areas beneath the Great Lakes, and parts of the submerged eastern seaboard are also...
The Loma Prieta, California, earthquake of October, 17, 1989: Marina District
Thomas D. O'Rourke, M. G. Bonilla, John Boatwright, Linda C. Seekins, Thomas E. Fumal, Hsi-Ping Liu, Charles S. Mueller, Richard E. Warrick, Robert E. Westerlund, Eugene D. Sembera, Leif Wennerberg, Harry E. Stewart, Ashraf K. Hussein, J. #NAME? Bardet, M. Kapuskar, G. R. Martin, J. Proubet, H. T. Taylor, J.T. Cameron, S. Vahdani, H. Yap, Jonathan W. Pease, Stephen K. Harris, John A. Egan, Charles R. Scawthorn, Keith A. Porter, Frank T. Blackburn
Thomas D. O'Rourke, editor(s)
1992, Professional Paper 1551-F
During the earthquake, a total land area of about 4,300 km2 was shaken with seismic intensities that can cause significant damage to structures. The area of the Marina District of San Francisco is only 4.0 km2--less than 0.1 percent of the area most strongly affected by the earthquake--but its significance...
Mineral and energy resources of the BLM Roswell Resource Area, east-central New Mexico
Susan B. Bartsch-Winkler, editor(s)
1992, Open-File Report 92-261
The sedimentary formations of the Roswell Resource Area have significant mineral and energy resources. Some of the pre-Pennsylvanian sequences in the Northwestern Shelf of the Permian Basin are oil and gas reservoirs, and Pennsylvanian rocks in Tucumcari basin are reservoirs of oil and gas as well as source rocks for...
Map, tables, and summary of fossil and isotopic age data, Mount Hayes Quadrangle, eastern Alaska range, Alaska
Warren J. Nokleberg, John N. Aleinikoff, J. Thomas Dutro Jr., Marvin A. Lanphere, Norman J. Silberling, Steven R. Silva, Thomas E. Smith, Donald L. Turner
1992, Miscellaneous Field Studies Map 1996-D
This report describes, summarizes, and interprets all known bedrock fossil and isotopic age studies for the Mount Hayes quadrangle, eastern Alaska Range, Alaska. The accompanying map shows the location of all known bedrock fossil and isotopic sample localities in the quadrangle on a generalized geologic base map. These fossil and...
Contrasting P‐T‐t paths: Thermochronologic evidence for a Late Paleozoic final assembly of the Avalon Composite Terrane in the New England Appalachians
R. P. Wintsch, J. F. Sutter, Michael J. Kunk, John N. Aleinikoff, Michael J. Dorais
1992, Tectonics 672-689
Strongly contrasting pressure‐temperature‐time paths for the Avalon composite terrane and the structurally overlying Putnam‐Nashoba zone in eastern New England obtained from thermochronologic and thermobarometric data are best explained by a late Paleozoic underthrusting of cover rocks by the Avalon composite terrane. We present new Ar and U‐Pb thermochronologic data that...
Rare earth, major and trace element composition of Leg 127 sediments
R.W. Murray, Marilyn R. Buchholtz ten Brink, Hans-Juergen Brumsack, David C. Gerlach, G. Price Russ
1992, Conference Paper, Proceedings of the Ocean Drilling Program, Scientific Results
The relative effects of paleoceanographic and paleogeographic variations, sediment lithology, and diagenetic processes on the final preserved chemistry of Japan Sea sediments are evaluated by investigating the rare earth element (REE), major element, and trace element concentrations in 59 squeeze-cake whole-round and 27 physical-property sample residues from Sites 794, 795,...

Julie A. Dumoulin, Anita G. Harris
Dennis K. Thurston, Kazuya Fujita, editor(s)
1992, Conference Paper, Proceedings: 1992 international conference on Arctic margins (MMS 94-0040)
Fault-bounded successions of pre-Carboniferous (meta)carbonate rocks occur throughout northern Alaska. Successions studied in detail are those in the York Mountains (Seward Peninsula), the western and eastern Baird Mountains (western Brooks Range), the Snowden Mountain area (central Brooks Range), and the Sublik and Sadlerochit Mountains (eastern Brooks range); they are correlated...
Contaminant transport in Massachusetts Bay
Bradford Butman
1992, Report
Construction of a new treatment plant and outfall to clean up Boston Harbor is currently one of the world's largest public works projects, costing about $4 billion. There is concern about the long-term impact of contaminants on Massachusetts Bay and adjacent Gulf of Maine because these areas are used extensively...
Holocene coastal development on the Florida peninsula
Richard Davis, Albert C. Hine, Eugene A. Shinn
1992, SEPM Special Publication (48) 193-212
The Florida peninsula contains five distinct coastal sections, each resulting from its own spectrum of coastal processes and sediment availability during a slowly rising, late Holocene sea level. The east coast barrier system is wave-dominated and has a large cuspate foreland (Cape Canaveral) near its middle. The Florida Keys and...
