Description:

Abstract:

Geo-Heat Center Geochemistry Database for the Great Basin. Documentation for this file is provided at: GeoHeat_intro_v2b Hot springs and wells of the western United States, from the Geo-Heat Center

Purpose: For geothermal exploration.

Supplemental_Information:

This is an ArcView and ArcGIS-compatible shapefile of the database. Missing geochemical data are represented by "-1". Geochemical data with "less-than" (<) symbols have been converted to one-half the detection limit value, with the exception of arsenic data, for which all entrees with "less than" symbols have been converted to "-1" (no data).
