Geothermometry

Geothermometry is a scientific method used to estimate the temperature of underground geothermal reservoirs by analyzing the chemical composition of geothermal fluids, such as hot springs or well waters. Certain dissolved minerals and gases in these fluids form or change at specific temperatures, acting like natural thermometers. By examining their concentrations, scientists can infer the temperature of the underground heat source without needing to directly access the hot rock. This information helps in assessing geothermal energy potential and managing geothermal resources sustainably.
