IAGA / IASPEI Joint Scientific Meeting 2025 in Lisbon, Portugal

At the IAGA / IASPEI Joint Scientific Meeting 2025 (31 Aug - 5 Sep), the IHFC organized the J10 symposium:

Heat flow measurements are fundamental for characterizing the Earth’s energy budget. They can evidence dynamic processes that take place on a regional scale, e.g. lithosphere extension, subduction, thrust folding, magma emplacement in the crust and thermal mobilization of minerals, driving processes such as metamorphism and the formation of economically important mineral deposits. Moreover, it is widely accepted that the brittle-ductile boundary, above which deformation is accompanied by seismic activity, is thermally controlled. In polar regions, the heat flow can affect the ice-sheet temperature and rheology, the basal melting, and the consequent mechanical decoupling at the ice-bedrock interface. On the other hand, the evaluation of subsurface thermal regimes is also important for geothermal energy applications, which, in their different technical aspects (electrical and direct uses, ground-source heat pumps, etc.), are becoming more prominent in the frame of renewable and sustainable resources. The symposium focuses on the results of experimental and theoretical studies concerning the influence of heat distribution on the main tectonic, rheological, seismological and crustal fluid flow processes, as well as on the geothermal potential of the areas. The symposium’s topics of interest could include, but are not limited to, the following areas:

global and local scale geodynamic processes and their relations with the thermal state of the lithosphere; understanding the mechanisms of heat transfer in continental and oceanic regions for better modelling the lithospheric thermal structure and identifying potentially exploitable geothermal areas; thermal studies addressing permafrost thawing, mineral and geothermal resource evaluation; advances in borehole and rock thermo-physical measurements and their relationship to a wide range of geodynamic processes; acquisition of new heat-flow data in a variety of geological realms; reviews of existing thermal data identifying key-knowledge gaps.

We welcome contributions that address these topics on both large areas and local or small-scale case studies, providing a platform for the exchange of ideas, methods, and concepts on the thermal aspects of the Earth’s interior.
