Chemical and Isotope Data: Basic Search
Introduction to the Database
Chemical and isotope data accumulated by two USGS Projects (led by I. Barnes and R. Mariner) over a time period of about 40 years can now be found using the basic search below. The data are primarily chemical and isotopic analyses of waters (thermal, mineral, or fresh) and associated gas (free and/or dissolved) collected from hot springs, mineral springs, cold springs, geothermal wells, fumaroles, and gas seeps. Additional information is available about the collection methods and analysis procedures.
The chemical and isotope data are stored in a MySQL database and accessed using PHP from a basic search form below.
