Prospects for mineral resource assessments on public lands: Proceedings of the Leesburg workshop
Simon M. Cargill, Steven B. Green, editor(s)
1986, Circular 980
Modern geological surveys pursue a wide spectrum of research activities in the earth sciences. From the beginning, however, one of the core tasks of any national geological survey has been the assessment and evaluation of its nation's mineral and fuel resources. The methods by which such assessments are carried out...

Principles of logic and the use of digital geographic information systems
Charles Joseph Robinove
1986, Circular 977
Digital geographic information systems allow many different types of data to be spatially and statistically analyzed. Logical operations can be performed on individual or multiple data planes by algorithms that can be implemented in computer systems. Users and creators of the systems should fully understand these operations. This paper describes...
Archaeology and public perception of a trans-scientific problem; disposal of toxic wastes in the unsaturated zone
Isaac Judah Winograd
1986, Circular 990
Predicting the effects of toxic-waste disposal on the environment over periods of millenia to hundreds of millenia is a transscientific problem; that is, one not fully addressed by quantitative scientific and engineering endeavors. Archaeology is a pertinent adjunct to such predictions in several ways. First, and foremost, archaeological records demonstrate...
The Georges Bank monitoring program 1985: Analysis of trace metals in bottom sediments during the third year of monitoring
Michael H. Bothner, R.R. Rendigs, Esma Campbell, M. W. Doughten, C.M. Parmenter, C. H. O’Dell, G.P. DiLisio, R. G. Johnson, J.R. Gillison, Norma Rait
1986, Circular 988
Of the 12 elements analyzed in bulk (undifferentiated) sediments collected adjacent to drilling rigs on Georges Bank, only barium was found to increase in concentration during the period when eight exploratory wells were drilled (July 1981 until September 1982). The maximum postdrilling concentration of barium (a major element in drilling...
Bibliography on ground water in glacial-aquifer systems in the Northeastern United States
Denise A. Wiltshire, Forest P. Lyford, A.J. Cohen
1986, Circular 972
The U.S. Geological Survey established the Regional Aquifer-System Analysis (RASA) program to evaluate major interconnected aquifers or groups of aquifers that share similar characteristics within a region. One of the objectives of the Northeastern Glacial RASA is to provide information on the occurrence and quality of ground water in glacial...

The Conterminous United States Mineral Appraisal Program; background information to accompany folio of geologic, geochemical, geophysical, and mineral resources maps of the Medford 1 degree x 2 degrees Quadrangle, Oregon and California
James G. Smith, R.J. Blakely, M. G. Johnson, N.J. Page, J.A. Peterson, D.A. Singer, C. L. Whittington
1986, Circular 976
The Medford 1 ? by 2 ? quadrangle in southern Oregon and northern California was studied by an interdisciplinary research team to appraise its mineral resources. The appraisal is based on geological, geochemical, and geophysical field and laboratory investigations, the results of which are published as a folio of maps,...
The Conterminous United States Mineral Assessment Program; background information to accompany folio of geologic, geochemical, geophysical, remote sensing, and mineral resource maps of the Wallace 1 degree x 2 degrees Quadrangle, Montana and Idaho
Jack Edward Harrison, David L. Leach, M. Dean Kleinkopf, Carl L. Long, Larry C. Rowan, Richard F. Marvin
1986, Circular 920
The Wallace 1? x 2 quadrangle in Montana and Idaho was studied by an interdisciplinary research team that included geologists, geochemists, and geophysicists, as well as specialists in isotopic dating and remote sensing. The basic data resulting from these studies, as well as the final metallic mineral resource assessments,...

Eruption in an ice-filled caldera, Mount Veniaminof, Alaska Peninsula: A section in The United States Geological Survey in Alaska: Accomplishments during 1983
M. Elizabeth Yount, Thomas P. Miller, Richard P. Emanuel, Frederic H. Wilson
1985, Circular 945
The more prominent of the two visible intracaldera cones of Mount Veniaminof went into eruption in early June 1983 and continued until early April 1984. Veniaminof is a 2,507-m-high composite cone having an 8 x 11-km summit caldera which formed 3,300-3,700 yr B.P. (Miller and Smith, 1977). The active 1.6x1.2-km...
Digital image processing techniques for detecting surface alteration - An application on the Alaska Peninsula: A section in The United States Geological Survey in Alaska: Accomplishments during 1983
James York, Frederic H. Wilson, Bruce M. Gamble
1985, Circular 945
The tectonic evolution of the Alaska Peninsula makes it a likely area for the discovery of significant mineral deposits. However, because of problems associated with remoteness and poor weather, little detailed mineral exploration work has been carried on there. This study focuses on using Landsat multispectral scanner data for the...
