James F. Gibbs, John C. Tinsley III, David M. Boore
2002, Open-File Report 2002-203
The U.S. Geological Survey (USGS), as part of an ongoing program to acquire seismic velocity and geologic data at locations that recorded strong-ground motions during earthquakes, has investigated five sites in the Fortuna, California region (Figure 1). We selected drill sites at strong-motion stations that recorded high accelerations (Table 1)...

Quality of economically extractable coal beds in the Gillette coal field as compared with other Tertiary coal beds in the Powder River basin, Wyoming and Montana
Margaret S. Ellis
2002, Open-File Report 2002-174
The Powder River Basin, and specifically the Gillette coal field, contains large quantities of economically extractable coal resources. These coal resources have low total sulfur content and ash yield, and most of the resources are subbituminous in rank. A recent U.S Geological Survey study of economically extractable coal in the...

User's guide to HYPOINVERSE-2000, a Fortran program to solve for earthquake locations and magnitudes
Fred W. Klein
2002, Open-File Report 2002-171
Hypoinverse is a computer program that processes files of seismic station data for an earthquake (like p wave arrival times and seismogram amplitudes and durations) into earthquake locations and magnitudes. It is one of a long line of similar USGS programs including HYPOLAYR (Eaton, 1969), HYPO71 (Lee and Lahr, 1972),...
Molybdenum recycling in the United States in 1998
John W. Blossom
2002, Open-File Report 2002-165
This report describes the flow of molybdenum in the United States in 1998 with emphasis on the extent to which molybdenum was recycled. Molybdenum was mostly recycled from products of molybdenum-bearing steels and superalloys, with some molybdenum products recovered specifically for their high molybdenum content. In 1998, 8,000 metric tons...
Asbestos: Geology, Mineralogy, Mining, and Uses
Robert L. Virta
2002, Open-File Report 2002-149
The term asbestos is a generic designation referring usually to six types of naturally occurring mineral fibers that are or have been commercially exploited. These fibers belong to two mineral groups: serpentines and amphiboles. The serpentine group contains a single asbestiform variety: chrysotile; five asbestiform varieties of amphiboles are known:...

2002, Open-File Report 2002-177
The 89 km long Tangle Lakes profile of 14 magnetotelluric (MT) stations begins 4 km south of the confluence of Augustana Creek and the Delta River in south central Alaska. The northernmost station, TLM13, is located just south of the Denali Fault in the rugged Clearwater Mountains. The north-south profile...
Rare Earth Element Mines, Deposits, and Occurrences
Greta J. Orris, Richard I. Grauch
2002, Open-File Report 2002-189
Data on rare earth (including yttrium) mines, deposits, and occurrences were compiled as part of an effort by the USGS and the University of Arizona Center for Mineral Resources to summarize current knowledge on the supply and demand outlook and related topics for this group of elements. Economic competition and...
Water-quality monitoring and studies of the formation and fate of trihalomethanes during the third injection, storage and recovery test at Lancaster, Antelope Valley, California, March 1998 through April 1999

The U.S. Geological Survey, in cooperation with the Los Angeles County Department of Public Works and the Antelope Valley-East Kern Water Agency, conducted three cycles of injection, storage, and recovery tests to evaluate the feasibility of artificially recharging ground water in the Lancaster area of Antelope Valley, California. During the...
Data from theodolite measurements of creep rates on San Francisco Bay region faults, California: 1979-2001
Jon S. Galehouse
2002, Open-File Report 2002-225
My purpose is to make our creep data on San Francisco Bay region active faults available to the scientific research community. My student research assistants and I measured creep (aseismic slip) rates on these faults from 1979 until my retirement from the project in 2001. These data are further described...
Thermodynamic data for modeling acid mine drainage problems: compilation and estimation of data for selected soluble iron-sulfate minerals
Bruch S. Hemingway, Robert R. Seal II, I-Ming Chou
2002, Open-File Report 2002-161
Enthalpy of formation, Gibbs energy of formation, and entropy values have been compiled from the literature for the hydrated ferrous sulfate minerals melanterite, rozenite, and szomolnokite, and a variety of other hydrated sulfate compounds. On the basis of this compilation, it appears that there is no evidence for an excess...

Post-glacial inflation-deflation cycles, tilting, and faulting in the Yellowstone Caldera based on Yellowstone Lake shorelines
Kenneth L. Pierce, Kenneth P. Cannon, Grant A. Meyer, Matthew J. Trebesch, Raymond D. Watts
2002, Open-File Report 2002-142
The Yellowstone caldera, like many other later Quaternary calderas of the world, exhibits dramatic unrest. Between 1923 and 1985, the center of the Yellowstone caldera rose nearly one meter along an axis between its two resurgent domes (Pelton and Smith, 1979, Dzurisin and Yamashita, 1987). From 1985 until 1995-6, it...
