Trace metals and major and rare earth elements in cuttings from five high-temperature wells in the northwest region of The Geysers, California, vapor-dominated geothermal system Trace metals and major and rare earth elements in cuttings from five high-temperature wells in the northwest region of The Geysers, California, vapor-dominated geothermal system
Temperatures within the main vapor-dominated steam reservoir at The Geysers geothermal field generally are in the range 238°C to 244°C. A few deep wells in the northwestern part of the field have penetrated beneath this reservoir into a second vapor-dominated reservoir where temperatures are >315°C, while vapor pressure remains nearly constant at about 35.9 bars (Walters et al., 1992)...

The Hanshin-Awaji Earthquake of January 17, 1995: Performance of lifelines The Hanshin-Awaji Earthquake of January 17, 1995: Performance of lifelines
This report describes the damage to lifelines caused by the 1995 Hanshin-Awaji (Kobe) earthquake in Japan. It begins with a summary of the earthquake's seismological characteristics which is followed by separate chapters that focus on the performance of lifelines in the affected region. In order of presentation, individual chapters discuss the damage to: 1) electric power networks; 2)...

Cerro Prieto geothermal field, Mexico; chemical analyses and other data for 58 samples collected in 1977-1979 Cerro Prieto geothermal field, Mexico; chemical analyses and other data for 58 samples collected in 1977-1979
This report releases the results of selected chemical analyses by the USGS of fluids collected from geothennal power production wells at the Cerro Prieto Geothennal Field, Mexico. Cerro Prieto, the world's largest producing hot-water geothennal field, is located 32 km southeast of Mexicali, Baja California. Comision Federal de Electricidad de Mexico (CFE) gave permission for, and...

Multichannel seismic-reflection profiling on the R/V Maurice Ewing during the Los Angeles Region Seismic Experiment (LARSE), California Multichannel seismic-reflection profiling on the R/V Maurice Ewing during the Los Angeles Region Seismic Experiment (LARSE), California
This report describes the acquisition of deep-crustal multichannel seismic-reflection data in the Inner California Borderland aboard the R/V Maurice Ewing, conducted in October 1994 as part of the Los Angeles Regional Seismic Experiment (LARSE). LARSE is a cooperative study of the crustal structure of southern California involving earth scientists from the U.S. Geological Survey, Caltech...

Preliminary geologic map of the Mount Hood 30- by 60-minute Quadrangle, Northern Cascade Range, Oregon Preliminary geologic map of the Mount Hood 30- by 60-minute Quadrangle, Northern Cascade Range, Oregon
This map shows the geology of the central and eastern parts of the Cascade Range in northern Oregon. The Quaternary andesitic stratovolcano of Mount Hood dominates the northwest quarter of the quadrangle, but nearly the entire area is underlain by arc-related volcanic and volcaniclastic rocks of the Cascade Range. Most stratigraphic units were emplaced since middle Miocene time, and all...
