Sketch maps showing areal extent, thickness, and amount of commercial-quality peat in deposits in and near Piscataquis and Somerset counties and northeastern Aroostook County, Maine
Cornelia Clermont Cameron, Michael K. Mullen
1981, Open-File Report 81-1320
Peat deposits in and near Piscataquis and Somerset Counties and northeastern Aroostook County, Maine, were investigated for their estimated potential as peat resources suitable for energy, horticultural, and agricultural uses. Fifty sketch maps illustrate the areal extent, thickness, and amount of commercial-quality peat. The total yield is estimated at 23,908,000...
Progress report on the effects of surface mining on the surface-water hydrology of selected basins in the Fort Union coal region, North Dakota and Montana
Douglas G. Emerson
1981, Open-File Report 81-678
The purpose of the investigation is to provide a means to assess the impacts on surface-water hydrology due to changes in land use resulting from surface mining of coal in the Fort Union Coal Region, North Dakota and Montana. The objectives of the study are to: (1) Determine premining hydrologic...
The potential for diamond-bearing kimberlite in northern Michigan and Wisconsin
William F. Cannon, M.G. Mudrey
1981, Circular 842
Between 1876 and 1913, diamonds were found in at least seven localities in southern and central Wisconsin. All were found in Pleistocene glacial deposits or Holocene river gravel. The bedrock kimberlite source for the diamonds is unknown but has been presumed to be in northern Canada, the only area north...
Hydrologic characteristics and possible effects of surface mining in the northwestern part of West Branch Antelope Creek basin, Mercer County, North Dakota
Mark E. Crawley, Douglas G. Emerson
1981, Water-Resources Investigations Report 81-79
Lignite beds and abundant discontinuous sandstone beds of the Paleocene Sentinel Butte Member of the Fort Union Formation and sand and gravel beds in the Quarternary glaciofluvial deposits (Antelope Creek aquifer) are the most important aquifers for domestic and livestock water supplies in the West Branch Antelope Creek basin. In...
Seismicity map of the state of North Dakota
B.G. Reagor, C. W. Stover, S. T. Algermissen
1981, Miscellaneous Field Studies Map 1326
The earthquake data shown on this map and listed in table 1 are a list of earthquakes that were originally used in preparing the Seismic Risk Studies in the United States in the United States (Algermissen, 1969) which have been recompiled and updated through 1977.  These data have been reexamined...
Seismicity map of the state of South Dakota
B.G. Reagor, C. W. Stover, S. T. Algermissen
1981, Miscellaneous Field Studies Map 1325
The earthquake data shown on this map and listed in table 1 are a list of earthquakes that were originally used in preparing the Seismic Risk Studies in the United States in the United States (Algermissen, 1969) which have been recompiled and updated through 1977.  These data have been reexamined...
National Water Data Exchange (NAWDEX) System 2000 data retrieval manual
Owen O. Williams, William A. Knecht
1981, Open-File Report 81-419
The manual offers general instructions on the use of SYSTEM 2000 to retrieve any type of data, and specific instructions on how to retrieve data from the U.S. Geological Survey 's Water Data Sources Directory and Master Water Data Index Data Bases. The manual is divided into five major sections...
Gulf of Mexico summary report 2, August 1981: A revision of Outer Continental Shelf oil and gas activities in the Gulf of Mexico and their onshore impacts: A summary report, September 1980
Kenneth J. Havran
1981, Open-File Report 81-620
The Gulf of Mexico Outer Continental Shelf (OCS) continues to be the most intensively developed offshore oil- and gas-producing region in the world. With the development of technology, exploration, development, and production are being extended to include areas off the coast of southwest Florida and deep-water areas near the Mississippi...
X-ray mineralogy of cores from two Guatemalan caldera lakes
Lawrence J. Poppe, Charles K. Paull, Christopher G. Newhall
1981, Open-File Report 81-1333
The U.S. Geological Survey (USGS), under the sponsorship of The Agency for International Development, in cooperation with Dartmouth College, collected 13 cores to study the sedimentation in two Guatemalan cauldera lakes, Atitlan and Ayarza....
Map showing paleontological control of Paleozoic stratigraphy in New England
Marland P. Billings, Peter T. Lyttle
1981, Miscellaneous Field Studies Map 1302
Assignment of Phanerozoic stratigraphic units to their proper place in the geologica time scale is based primarily on paleontology.  Radiometric methods are becoming increasingly important (Naylor, 1976), particularly where paleontological data are lacking.  This map and text are concerned only with the paleontological data bearing on the Paleozoic stratigraphy of...
Preliminary map showing recently active breaks along the Maacama Fault zone between Hopland and Laytonville, Mendocino County, California
E. H. Pampeyan, Philip W. Harsh, J.M. Coakley
1981, Miscellaneous Field Studies Map 1217
The southernmost 15 km of this map is a product of a study that began in 1975 as part of a study of recency of faulting in coastal California (Ziony and others, 1974; Buchanan-Banks and others, 1978; Pampeyan , 1979). In February 1975, after being shown evidence of recent faulting...
Ground-water reconnaissance of part of the lower Kenai Peninsula, Alaska
G.L. Nelson, P.R. Johnson
1981, Open-File Report 81-905
Most residential and industrial development of the Lower Kenai Peninsula, Alaska, is along the coast of Cook Inlet. Most of the information about subsurface conditions is obtained from wells along the coast. Ground water is recharged by local precipitation, and slow drainage of ground water to the streams maintains streamflow...
