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 ³ 100 °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
