Upper-crustal structure from NTS to Carrizozo, N.M. from Rayleigh-wave data. Final report

Description: Seismic waves from the underground nuclear test ``Serena`` were recorded by a linear array of nine seismographs spaced more or less regularly from near the Nevada Test Site to Carrizozo, New Mexico. The authors have obtained Rayleigh wave group and phase velocity data from these stations, and have inverted the phase velocity data for models of the upper crust of the southern Colorado Plateau and the Rio Grande rift. The major difference between the two models is the thickness of their sedimenta… more

Fractal nature and scaling of normal faults, Rio Grande rift, NM: Implications for growth and strain

Description: In this paper I introduce a suite of Quaternary normal faults from within an active continental rift and characterize the nature of the relationship between fault dimensions. I address the statistical and geological significance of the fractal analysis used in that characterization and discuss the tectonic implications. Specifically, I suggest (1) scaling laws for a previously unanalyzed population of young normal faults in rift environment; (2) implications for fault growth models in this area… more

Trace element characteristics of lithospheric and asthenospheric mantle in the Rio Grande rift region

Description: Trace element analyses of 10 mafic volcanic rocks from the Colorado Plateau transition zone, Colorado Plateau, Rio Grande rift, and Great Plains were obtained to characterize the trace element characteristics of asthenospheric and lithospheric mantle beneath these regions. Characterization of these mantle reservoirs using the trace element contents of basalts allows one to track the response of the lithosphere to continental rifting and extension.

Active And Passive Seismic Studies of Geothermal Resources in New Mexico and Investigations of Earthquake Hazards to Geothermal Development

Description: Seismic data were collected in southwestern New Mexico to investigate the sources of the geothermal anomalies and to investigate the potential earthquake hazards of geothermal development. No major crustal structure anomalies have been located related to known geothermal resources, and no areas of continual seismicity have been identified, which is interpreted to indicate a lack of active, or recently active crustal intrusions in southwestern New Mexico. Without a magnetic heat source, the geot… more

West Texas geothermal resource assessment. Part I. Geothermal exploration in Trans-Pecos, Texas. Final report

Description: All of the new drilling for geothermal gradient and heat flow studies have been concentrated in an area near Hueco Tanks State Park. Interest in the area was raised by the silica geothermometry map of Hoffer (1979) and its proximity to El Paso, which is less than 25 miles away and expanding rapidly toward the area of geothermal interest. Several industries in El Paso appear to be potential users of non-electrical grade hot waters. A total of 14 holes have been drilled for geothermal gradient an… more

Water geochemistry of the Lucero Uplift, New Mexico: geothermal investigation of low-temperature mineralized fluids

Description: A detailed geochemical investigation of 27 waters of the Lucero uplift, central New Mexico, was performed to determine if the fluids originate from a high-temperature geothermal system along the Rio Grande rift. Two types of mineralized water issue from the Lucero region: a relatively saline (high-Cl, high-SO/sub 4/) type and a relatively dilute (low-Cl, high-SO/sub 4/) type. Emergence temperatures of both types range from 12 to 26/sup 0/C. Chemical data and thermodynamic and geothermometer cal… more

Geothermal potential on Kirtland Air Force Base lands, Bernalillo County, New Mexico

Description: Extensive sampling and geochemical analysis of groundwater in and near the base disclosed no significant geothermal parameters. However, structural conditions and current hydrologic regimes strongly suggest that thermal waters would be masked by near surface, low temperature meteoric water originating as rain and snowfall in the nearby mountains. Controlled source audio-magnetotelluric (CSAMT) electromagnetic techniques, refraction seismic experiments, and gravity traverses were utilized on the… more

Three-dimensional gravity ideal body studies in rough terrain

Description: An approach to the interpretation of potential field anomaly data is to maximize or minimize some non-linear scalar property of solutions fitting the data. As an example, a comparison of 2-D and 3-D gravity ideal body results from the Lucero Uplift, a westward-tilted fault block located on the western flank of the Rio Grande rift, is discussed. The anomaly was analyzed to obtain bounds on the density contrast, depth of burial, and minimum thickness of its sources. Based on a synthesis of the gr… more
