Abstract
<p><strong>Abstract.</strong> Southeastern Idaho exhibits numerous warm springs, warm water from shallow wells, and hot water from oil and gas test wells that indicate a potential for geothermal development in the area. We have estimated reservoir temperatures from chemical composition of thermal waters in southeastern Idaho using an inverse geochemical modeling technique (Reservoir Temperature Estimator, RTEst) that calculates the temperature at which multiple minerals are simultaneously at equilibrium while explicitly accounting for the possible loss of volatile constituents (e.g., CO<sub>2</sub>), boiling and/or water mixing. The temperature estimates in the region varied from moderately warm (59<span class="thinspace"></span>°C) to over 175<span class="thinspace"></span>°C. Specifically, hot springs near Preston, Idaho, resulted in the highest reservoir temperature estimates in the region.</p>
