TS3.1 | Deformation and faults: from deep to shallow crust and from long term to seismic hazard
Deformation and faults: from deep to shallow crust and from long term to seismic hazard
Convener: Riccardo Lanari | Co-conveners: Silvia Crosetto, Fabio Corbi, Ylona van Dinther
Deformation zones and faulting processes develop in several geodynamic environments, involving deep and/or shallow crust. In active tectonics contexts, unravelling the faults’ long-term evolution has a crucial impact for seismic hazard assessment. Multiple parameters are expected to control fault evolution, such as the tectonic and geodynamic setting, erosion, the amount of sediments deposited on the hanging wall, fluids circulation, or lithology. While the effects of some of these parameters are well established, many others are still poorly constrained by actual data.
This session aims to better define the properties of faults and deformation zones, and to understand how their characteristics change over time. We invite contributions dealing with faulting and deformation processes (normal, reverse and strike-slip) worldwide, in different geodynamic contexts, from outcrops to mountain ranges, and from the long-term to single seismic events. Since a multidisciplinary approach is the key to deep understanding, studies involving diverse methods such as field-data analysis, paleoseismic trenching, stable isotopes, low temperature thermochronology, syn-kinematic U/Pb dating, cosmogenic exposure dating, petrographic analysis, or analogue/numerical modelling are welcome.
