Description:
Abstract:
Description This is a specialized, reduced set of geochemical data on hot springs and geothermal systems of Nevada designed to be used for spatial statistical analysis. This data set has been used to assess correlations between geothermal systems in Nevada and geological, geochemical, and geophysical phenomena. One of the more distinctive features of this data set is the fact that no two data points lie less than 10 kilometers from each other. This restriction was imposed in order to minimize distortions in statistics when large numbers of individual spring or well analyses exist for a "single geothermal system". Selection Criteria: This shapefile contains all geothermal systems in Nevada that fit the following restrictive criteria: 1) Unless measured temperatures were 100 C, no geothermal system was included if geothermometer estimates were not available. 2) A minimum distance of 10 km between geothermal systems was required. Higher temperature systems had preference over lower temperature systems where two candidates occurred less than 10 km apart. 3) Oil wells greater than 500 meters in depth were not used, because in many of them, temperatures don't appreciably exceed the regional gradient.
Purpose:
For geologic, mineral, or geothermal exploration For targeting high-temperature geothermal systems
