State-of-the-art for evaluating the potential impact of tectonism and volcanism on a radioactive waste repository

Description: Most estimates of the time required for safe isolation of radioactive wastes from the biosphere range from 100,000 to 1,000,000 years. For such long time spans, it is necessary to assess the potential effects of geologic processes such as volcanism and tectonic activity on the integrity of geologic repositories. Predictions of geologic phenomena can be based on probabilistic models, which assume a random distribution of events. The necessary historic and geologic records are rarely available to… more

Correlation of alluvial deposits at the Nevada Test Site

Description: Because characteristics of rock layers and problems in drilling must be studied before radioactive waste can be safely contained, an evaluation was made of methods for correlating alluvial deposits at Yucca Flat of the Nevada Test Site (NTS). Although correlation of Tertiary volcanic tuff beds at the NTS has been successfully achieved, correlation of stratigraphic zones in the overlying alluvium has posed technical difficulties. We have evaluated several methods for correlating alluvial deposit… more

Evidence of former higher temperatures from alteration minerals, Bostic 1-A well, Mountain Home, Idaho

Description: Cuttings from the silicic volcanics in the Bostic 1-A well near Mountain Home, Idaho have been examined petrographically with the assistance of x-ray diffraction and electron microprobe analyses. Results indicate that these rocks have been subjected to much higher temperatures than were observed in the well in 1974, when a static temperature log was run. It is not known to what extent the alternation may be due to greater depth of burial in the past, or whether it resulted from an early hydroth… more

Interpretation of a dipole-dipole electrical resistivity survey, Colado geothermal area, Pershing County, Nevada

Description: An electrical resistivity survey in the Colado geothermal area, Pershing County, Nevada has defined areas of low resistivity on each of five lines surveyed. Some of these areas appear to be fault controlled. Thermal fluids encountered in several drill holes support the assumption that the hot fluids may be associated with areas of low resistivity. The evidence of faulting as interpreted from modeling of the observed resistivity data is therefore particularly significant since these structures m… more

Convective heat transport in geothermal systems

Description: Most geothermal systems under exploitation for direct use or electrical power production are of the hydrothermal type, where heat is transferred essentially by convection in the reservoir, conduction being secondary. In geothermal systems, buoyancy effects are generally important, but often the fluid and heat flow patterns are largely controlled by geologic features (e.g., faults, fractures, continuity of layers) and location of recharge and discharge zones. During exploitation, these flow patt… more

Geothermic model for the rise of deeper groundwater along faults in unconsolidated rocks

Description: A simple model was derived which may be used to explain measured temperature anomalies in areas of unconsolidated rock containing faults. It is assumed that deep groundwater rises along the path provided by the faulting. The calculations were performed using temperature data from the Niederrhein--Bucht. The model yields a quantitative relationship between the vertical flow of groundwater and the temperature anomalies observed. The primary results indicate that the quantity of water flow require… more

Geological Interpretation of Self-Potential Data From the Cerro Prieto Geothermal Field

Description: A source mechanism based on concepts of irreversible thermodynamics and consisting of heat or fluid flow along a north-south trending zone of faulting is proposed for the self-potential anomaly measured over the Cerro Prieto geothermal reservoir. The source region is represented by a vertical plane of that separates regions of differing streaming potential or thermoelectric coupling coefficients. The coupling coefficient contrast could be caused by vertical offset of rock units along faults. Th… more
