Terrestrial heat flow is a measure of the thermal energy flux from the interior of the Earth. This parameter provides fundamental information on the Earth’s energy budget, subsurface thermal structure, lithosphere thermo-tectonic history and bulk chemical composition (especially concerning the radiogenic heat-producing elements of the crust). Moreover, analyses of heat flow data are essential to evaluate the potential of geothermal energy and to reconstruct paleoclimate change on regional and global scales. Heat flow data are conventionally determined from the combination of geothermal gradient, obtained from underground temperature logs, and rock thermal conductivity measurements, often derived from laboratory experiments. High-quality heat flow measurements require appropriate raw data reduction, because both geothermal gradient and thermal conductivity are subject to site-specific perturbations associated with geological, geographical, hydrological, and even climatic settings. The major objective of this symposium is to provide a forum for discussions on all aspects related to the terrestrial heat-flow measurements and interpretation. We welcome contributions that describe results in theoretical and/or experimental works, as well as on the use of heat flow and underground thermal data for the exploration of geothermal energy.
