Dataset of aggregate producers in New Mexico
Greta J. Orris
2000, Open-File Report 2000-11-B
This report presents data, including latitude and longitude, for aggregate sites in New Mexico that were believed to be active in the period 1997-1999. The data are presented in paper form in Part A of this report and as Microsoft Excel 97 and Data Interchange Format (DIF) files in Part...
Update and revisions for Open-File Report 98-624, synthetic precipitation leaching procedure (SPLP) leachate chemistry data for solid mine-waste composite samples from the Silverton and Leadville districts in Colorado
Philip L. Hageman, George A. Desborough, Paul J. Lamothe, Peter M. Theodorakos
2000, Open-File Report 2000-150
This report supersedes, revises, and updates information and data previously released in Open-File Report 98-624 (Montour and others, 1998). Data for this report were derived from leaching of mine-waste composite samples using a modification of E.P. A. Method 1312, Synthetic Precipitation Leaching Procedure (SPLP). In 1997, members of the U.S....
Preliminary model of the pre-Tertiary basement rocks beneath Yucca Flat, Nevada Test Site, Nevada, based on analysis of gravity and magnetic data
Geoffrey A. Phelps, Edwin H. McKee, D. Sweetkind, V.E. Langenheim
2000, Open-File Report 2000-134
The Environmental Restoration Program of the U.S. Department of Energy, Nevada Operations Office, was developed to investigate the possible consequences to the environment of 40 years of nuclear testing on the Nevada Test Site. The majority of the tests were detonated underground, introducing contaminants into the ground-water system (Laczniak and...
Analytical data for reconnaissance geochemical samples from mine dumps, stream sediments and waters at the Thompson Creek Tungsten Mine, Custer County, Idaho
B. S. Van Gosen, R. G. Eppinger, J. M. Hammarstrom, Paul H. Briggs, J.G. Crock, C. Gent, A. L. Meier, S. J. Sutley, P. M. Theodorakos
2000, Open-File Report 2000-239
The Thompson Creek mine is an inactive and abandoned tungsten mine located along Thompson Creek about 10.5 miles (17 km) northwest of Clayton, Idaho (see location map in file LOCATION.PDF). The mine consisted initially of open pit mining of outcrops and later of underground workings accessed by a single adit....
Field estimates of gravity terrain corrections and Y2K-compatible method to convert from gravity readings with multiple base stations to tide- and long-term drift-corrected observations
Donald Plouff
2000, Open-File Report 2000-140
Gravity observations are directly made or are obtained from other sources by the U.S. Geological Survey in order to prepare maps of the anomalous gravity field and consequently to interpret the subsurface distribution of rock densities and associated lithologic or geologic units. Observations are made in the field with gravity...
Depth to bedrock in the upper San Pedro Valley, Cochise County, southeastern Arizona
M. E. Gettings, Brenda B. Houser
2000, Open-File Report 2000-138
The thickness, distribution, and character of alluvial sediments that were deposited in the structural subbasins of the upper San Pedro basin in southeastern Arizona during the late Cenozoic provide important constraints on ground-water availability of the area. Two sedimentary units are recognized; the Oligocene and Miocene Pantano(?) Formation and an...
Selected hydrologic data, through water year 1998, Black Hills Hydrology Study, South Dakota
Daniel G. Driscoll, Wendell L. Bradford, Michael J. Moran
2000, Open-File Report 2000-70
This report presents water-level and water-quality data that have been collected or compiled, through water year 1998, for the Black Hills Hydrology Study. This study is a long-term coop-erative effort between the U.S. Geological Survey, the South Dakota Department of Environment and Natural Resources, and the West Dakota Water Development...
Distribution of selected volatile organic compounds determined with water-to-vapor diffusion samplers at the interface between ground water and surface water, Centredale Manor site, North Providence, Rhode Island, September 1999
Peter E. Church, Forest P. Lyford, Scott Clifford
2000, Open-File Report 2000-276
Volatile organic compounds are present in soils and ground water at the Centredale Manor Superfund Site in North Providence, Rhode Island. In September 1999, water-to-vapor diffusion samplers were placed in the bottom sediments of waterways adjacent to the site to identify possible contaminated ground-water discharge areas. The approximate12-acre site is...
Analytical results for total-digestions, EPA-1312 leach, and net acid production for twenty-three abandoned metal-mining related wastes in the Boulder River watershed, northern Jefferson County, Montana
David L. Fey, George A. Desborough, Christopher J. Finney
2000, Open-File Report 2000-114
IntroductionMetal-mining related wastes in the Boulder River basin study area in northern Jefferson County, Montana, have been implicated in their detrimental effects on water quality with regard to acid generation and toxic-metal solubilization during snow melt and storm water runoff events. This degradation of water quality is defined chiefly by...
Program to convert SUDS2ASC files to a single binary SEGY file
Mark Goldman
2000, Open-File Report 2000-141
This program, SUDS2SEGY, converts and combines ASCII files created using SUDS2ASC Version 2.60, to a single SEGY file. SUDS2ASC has been used previously to create an ASCII file of three-component seismic data for an individual recording station. However, many seismic processing packages have difficulty reading in ASCII data. In addition, it...

2000, Open-File Report 2000-157
The purpose of this report is to provide information on how and why we deploy seismic instruments in and around building structures. The recorded response data from buildings and other instrumented structures can be and are being primarily used to facilitate necessary studies to improve building codes and therefore reduce losses...
A paleoecologic reconstruction of the history of Featherbed Bank, Biscayne National Park, Biscayne Bay, Florida
Jeffery R. Stone, T. M. Cronin, G. L. Brewster-Wingard, S. E. Ishman, B. R. Wardlaw, C. W. Holmes
2000, Open-File Report 2000-191
Using multiple-proxy biological indicators, a paleoecological history of the past 550 years of Featherbed Bank, Biscayne Bay, has been reconstructed from a short (2.26 m) sediment core. Paleoecological changes in ostracode, mollusc, and foraminifer assemblages show that core SEI297-FB-1 can be divided into three distinctly different zones, which together provide...
