Preliminary geologic map of the Little Piute Mountains, California: A digital database
Keith A. Howard, Michael L. Dennis, Karl Karlstrom, Geoffrey A. Phelps
1997, Open-File Report 97-693
The Little Piute Mountains Digital database contains digital geologic and geographic information for the study area. The geology was mapped at a scale of 1:8,000, and the topographic information was input from the Little Piute Mountains, CA 1:24,000 quadrangle. The accuracy of the spatial information is limited to the input...
Maps showing the surficial geology of the Culebra shelf, Puerto Rico
M. A. Hampton, M.E. Torresan, Juan L. Trias, D. W. Folger, F. L. Wong
1997, Open-File Report 97-290
This study presents the surficial and shallow subbottom geology of the insular shelf around Culebra, Puerto Rico. In view of the need for sand and gravel for construction purposes in the area, we inferred the thickness of unlithified, surficial sediment deposits from high-resolution acoustic-reflection profiles and described seafloor sediment samples...
Debris-flow hazards in areas affected by the June 27, 1995, storm in Madison County, Virginia
B. A. Morgan, G. F. Wieczorek, R. H. Campbell, P. L. Gori
1997, Open-File Report 97-438
A severe storm on June 27, 1995 triggered hundreds of rock, debris and soil slides from the steep hillsides of Madison County, Virginia. Most of these transformed into debris flows that inundated areas downslope causing damage to structures, roads, utilities, livestock and crops. This report contains an analysis of areas...
Identification of internal flow dynamics in two experimental catchments
D.P. Hansen, A.J. Jakeman, C. Kendall, G. Weizu
1997, Mathematics and Computers in Simulation (43) 367-375
Identification of the internal flow dynamics in catchments is difficult because of the lack of information in precipitation -stream discharge time series alone. Two experimental catchments, Hydrohill and Nandadish, near Nanjing in China, have been set up to monitor internal flows reaching the catchment stream at various depths, from the...
Sub-crop geologic map of pre-Tertiary rocks in the Yucca Flat and northern Frenchman Flat areas, Nevada Test Site, southern Nevada
J. C. Cole, Anita G. Harris, Ronald R. Wahl
1997, Open-File Report 97-678
This map displays interpreted structural and stratigraphic relations among the Paleozoic and older rocks of the Nevada Test Site region beneath the Miocene volcanic rocks and younger alluvium in the Yucca Flat and northern Frenchman Flat basins. These interpretations are based on a comprehensive examination and review of data for...
1996 annual report on Alaska's mineral resources
Jill L. Schneider
1997, Circular 1142
This is the fifteenth annual report that has been prepared in response to the Alaska National Interest Lands Conservation Act. Current Alaskan mineral projects and events that occurred during 1995 are summarized. For the purpose of this document, the term 'minerals' encompasses both energy resources (oil and gas, coal and...
