Deformation in the cryosphere and lithosphere of Earth and other planets occurs by creep and fracture of highly anisotropic polycrystalline materials such as ice, quartz, calcite, feldspar, pyroxene and olivine. In these materials deformation mechanisms and rheology are complex and challenging to include in modeling studies of cryosphere and lithosphere dynamics. The interdisciplinary session should bring together researchers from different fields, working on a similar topic: understanding cryosphere and lithosphere rheology based on the material properties. We wish to encourage contributions from glaciology (land, sea and planetary ice), structural geology, geodynamics and planetology. We welcome contributions dealing with all aspects of ice and mineral rheology, from brittle to ductile behaviour; including the influence of porosity, fluids, impurities, second phases; considering the texture development and recrystallization impacts on rheology; the brittle-ductile transition; coupling deformation of cryosphere and lithosphere.
This session is a contribution from the research networking programme on the Micro-Dynamics of ICE, Micro-DICE www.esf.org/microdice
