We warmly invite you to contribute to the following session at this year's AGU Fall Meeting:
T18: Heat Transfer from Pluton to Plate Scales
Invited speakers: Drew Coleman, University of North Carolina Anne Hofmeister, Washington University in St Louis Klaus Regenauer-Lieb, CSIRO, University of Western Australia
Description: Most geologic processes within Earth’s interior are driven by heat transfer, including magma generation, volcanism, geothermal systems, and ore deposition. On the plate scale, heat transfer within the lithosphere is primarily by conduction, and the geotherm controls the rheology of the plates and the evolution of mountain belts. Hydrothermal circulation in the mid- to upper crust can affect surface measurements of heat flow, and the contact metamorphic signature of large intrusions. Additional considerations include temperature- and composition-dependent thermal properties such as thermal diffusivity and heat capacity, the spatial distribution of radioactive elements in continental crust, compositional and fabric-related anisotropy, advective transport by magmas, and latent heat of melting and crystallization. We welcome contributions describing laboratory, observational, numerical or theoretical investigations pertaining to thermal properties of rocks and magmas, and to the thermal evolution of the lithosphere on scales from individual magma chambers and plutons to batholiths, orogenic belts and plates.
