D.Y. Venezky S. Hurwitz Robert H. Mariner 2006 <p>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 a <a href="http://hotspringchem.wr.usgs.gov/basicsearch.php" data-mce-href="http://hotspringchem.wr.usgs.gov/basicsearch.php">basic web search</a> or through an <a href="http://hotspringchem.wr.usgs.gov/WorldKit" data-mce-href="http://hotspringchem.wr.usgs.gov/WorldKit">image search </a>(left). 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 <a href="http://hotspringchem.wr.usgs.gov/info.php" data-mce-href="http://hotspringchem.wr.usgs.gov/info.php">collection methods and analysis procedures</a>.</p><p>The chemical and isotope data are stored in a MySQL database and accessed using PHP from a basic search form below.
