26th General Assembly 2015 in Prague, Czech Republic

At the 26th IUGG General Assembly, the IHFC organized the “Terrestrial Heat Flow” Symposia

S13 Terrestrial Heat Flow

Convener: Massimo Verdoya (Genoa, Italy) S13a Terrestrial Heat Flow: Subsurface Thermal Evaluation - Resources and Signals Convener: Massimo Verdoya (Genoa, Italy) Co-convener: Makoto Taniguchi (Kyoto, Japan) Description

Evaluation of subsurface thermal regimes is important in terms of 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 the renewable and sustainable. Subsurface thermal evaluation is also important to discover the signals of climate change related to global warming. Subsurface warming occurs all over the world due to global warming and heat island effects. Signals and changes of the subsurface thermal environment can be used not only for the reconstruction of climate change, but also for the study of the effect of urbanization and/or groundwater flow. In this symposium, subsurface thermal evaluations will be discussed in terms of resources and signals.

S13b Terrestrial Heat Flow: Lithosphere Heat Flow and Its Relationships with Tectonics, Seismicity and Crustal Fluid Circulation Convener: Massimo Verdoya (Genoa, Italy) Co-convener: Valiya Hamza (Rio de Janeiro, Brasil) Description

The terrestrial heat flow constitutes the principal surface boundary constraint for inferring the thermal structure of the lithosphere and can be regarded as a piece of evidence of dynamic processes, such as extension, subduction, and thrust folding, that take place on a regional scale. Moreover, it is widely accepted that the temperatures below which deformation is accompanied by seismic activity are related to the thermally controlled brittle-ductile boundary. Circulation of fluids in crust is known to bias the lithosphere heat-flow data, which are usually interpreted under the assumption of a purely conductive thermal regime. Thus, detailed understanding of advective versus conductive heat transfer in continental and oceanic regions is crucial for a better modelling of the lithosphere thermal structure. The focus of the symposium is on advances in geothermics in relation to tectonic, rheological, seismological and crustal fluid flow processes that can contribute to improved understanding of the thermal regime of the lithosphere. We welcome contributions that describe results in experimental and theoretical works on the importance of heat transfer by conduction and by fluid flow and that explore their relationships with the main tectonic processes.
