Professional papers are mainly comprehensive scientific reports of wide and lasting interest and importance to professional scientists and engineers. Included are reports on the results of resource studies, and of topographic, hydrologic, and geologic investigations. They also include collections of related papers addressing different aspects of a single scientific topic.

P 1406-B. ARIZONA. Geohydrology and water resources of alluvial basins in south-central Arizona and parts of adjacent states, by T. W. Anderson, G. W. Freethey and Patrick Tucci. 1992. p. B1-B67. 3 plates in pocket. (Regional Aquifer-System Analysis; Southwest alluvial basins, Arizona and adjacent states.) (Supersedes Open-file report 89-378.) $4.50.

The purpose of the study was to develop a better understanding of the extent and workings of the hydrologic systems in the alluvial basins of the Southwest. The approach to the study included evaluation of available data and categorization of the basin aquifers into groups on the basis of the similarity of lithology and flow conditions so that study results can be transferred to unstudied basins within a categorized group.

P 1505-A. COLORADO, NEW MEXICO. Geologic framework of pre-Cretaceous rocks in the Southern Ute Indian Reservation and adjacent areas, southwestern Colorado and northwestern New Mexico, by S. M. Condon. Prepared in cooperation with the Southern Ute Tribe and the U.S. Bureau of Indian Affairs. 1992. p. A1-A56. 1 plate in pocket. (Geology and mineral resources of the Southern Ute Indian Reservation, edited by R. S. Zech.) $3.75.

This report is a discussion and summary of Jurassic and older rocks in the Southern Ute Indian Reservation and adjacent areas on the bases of the analysis of geophysical logs and the observations of outcrops. The reservation, which is located in the northern San Juan Basin, has been the site of deposition of sediments for much of the Phanerozoic.


Bulletins contain significant data and interpretations that are of lasting scientific interest but are generally more limited in scope or geographic coverage than professional papers. They include the results of resource studies and of geologic and topographic investigations; as well as collections of short papers related to a specific topic.

B 1921. Text and references to accompany "Map showing the thickness and character of Quaternary sediments in the glaciated United States east of the Rocky Mountains", by D. R. Soller. 1992. 54 p. $3.25.

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 included on the map. The map has three components that, together, provide the first regional three-dimensional view of these deposits. These map components are the surface distribution of Quaternary sediments, the total thickness of Quaternary sediments, and the distribution of significant buried Quaternary units. For many areas, this is the first map of Quaternary sediment thickness published at any scale. This report provides supporting information for the map, preliminary interpretations of sediment distribution, and the list of geologic sources used to generate the map.

B 1984. MINNESOTA. Precious- and base-metal mineralization in the west-central Vermilion District, portions of St. Louis, Lake, and Cook counties, northeastern Minnesota, by H. V. Alminas, J. B. McHugh, U.S. Geological Survey; and E. C. Perry, Jr., Northern Illinois University. Field work done in cooperation with the Minnesota Geological Survey. 1992. 37 p. 2 plates in pocket. $2.50.

Geochemical sampling centered on the Archean greenstone belt of the Vermilion District indicates two major areas mineralized with respect to precious and base metals. The more pronounced anomalous area, centered on Lake Vermilion, exhibits gold content in soils as high as 1.1 ppm; zonation of elements is pronounced. The second gold-bearing area lies between Fall and Jasper lakes; zonation is less evident here. The mineralization appears largely related to buried epizonal granite and syenite and to lamprophyric rocks intruded during the Algoman Orogeny; northeast-trending faults also seem to have localized the mineralization.

B 1990-C. ALASKA. Age of tephra beds at the Ocean Point dinosaur locality, North Slope, Alaska, based on K-Ar and 40Ar/39 Ar analyses, by J. E. Conrad, E. H. McKee and B. D. Turrin. 1992. p. C1-C12. (Evolution of sedimentary basins; North Slope basin.) $1.25.

Tephra layers above and below dinosaur-bone-bearing beds of the Prince Creek Formation, North Slope, Alaska, yield radiometric ages on glass shards of 68-71 Ma (latest Cretaceous age). The dating methods include K-Ar, Ar/Ar total-fusion, and Ar/Ar age-spectrum techniques.


Water-supply papers include reports on the geology, hydrology, quality, recoverability, and utilization of water resources. They include also several series of statistical reports on streamflow, floods, ground-water levels, and water quality.

W 2295-C. COLORADO, OHIO. Water-quality data-collection activities in Colorado and Ohio; Phase III, Evaluation of existing data for use in assessing regional water-quality conditions and trends, by J. M. Norris, Janet Hren, D. N. Myers, T. H. Chaney and C. J. Childress. 1992. p. C1-C46. (Water-quality datacollection activities in Colorado and Ohio.) (Supersedes Open-file report 89-391.) $3.25.

Analysis of existing data from water-quality data-collection sites in Colorado and Ohio indicate that few areas in either state have data suitable for use in regional or national water-quality assessments, based on the amount of data available from the sites and the areal distribution of the sites. The analyses were for determining current surface-water and ground-water conditions and trends and for determining the effects of natural and human factors on water quality.

W 2379. ARIZONA. Climatic variability and flood frequency of the Santa Cruz River, Pima County, Arizona, by R. H. Webb and J. L. Betancourt. Prepared in cooperation with the Pima County Department of Transportation and Flood Control District. 1992. 40 p. (Supersedes Open-file report 90-553.) $2.75.

An apparent increase in flood magnitude during the past two decades raises concern that the annual flood series is nonstationary in time. The apparent increase is accompanied by more annual floods occurring in fall and winter and fewer in summer. The increase is mostly caused by an increase in recurvature of dissipating tropical cyclones into the Southwestern United States during El Niño-Southern Oscillation conditions.


Circulars present technical or nontechnical information of wide popular interest in a format designed for distribution at no cost to the public. They are published to disseminate administrative information or important scientific information of an ephemeral nature.

C 1059. Proceedings of the 1988 U.S. Geological Survey workshop on the Geology and geohydrology of the Atlantic Coastal Plain, edited by G. S. Gohn, U.S. Geological Survey. Partially prepared in cooperation with the New Jersey Geological Survey, Virginia State Water Control Board, Maryland Geological Survey, Southwest Florida Water Management District, Pinellas County (Florida) Sewer System and the Florida Department of Environmental Regulation. 1992. 158 p.

This report is a collection of short scientific papers that discuss research presented at a workshop entitled "U.S. Geological Survey workshop on the Geology and geohydrology of the Atlantic Coastal Plain." The workshop was held at the U.S. Geological Survey's National Center in Reston, Va., on September 28-29, 1988, and was attended by scientists from the USGS and from geological surveys and water-resource agencies representing seven Atlantic Coastal Plain states. The reports cover a wide range of coastal plain earth-science topics, including paleontology, stratigraphy, structure, offshore studies, ground-water quality, and ground-water flow.
