Dear colleagues, Since abstract submission deadline is approaching fast, we join the endless line of reminder emails and draw your attention back to the new PICO session '*Dynamics of dilatant faults and fractures (co-organized, TS2.4/GD2.13)*' at EGU 2019. The session focuses on all aspects of dilatant and hybrid failure in rocks from micro- to macroscale, from fracturing to faulting (see session abstract below). We invite contributions from numerical and analog modeling, field work, geophysics and other methods in the disciplines of geomechanics, fluid rock interactions, mineralogy, hydrology and age dating. This session aims to bring together researchers with interest in dilatant faults and fractures, that have been scattered over multiple sessions in the past years. Follow this link for more information and abstract submission: https://meetingorganizer.copernicus.org/EGU2019/session/30737 * **Deadline for abstract submission: January 10th, 2019* Looking forward to an exciting session at EGU, Best Regards, Michael Kettermann & Christoph von Hagke _______________________________________________________________________________ Session description: TS2.4/GD2.13 *Dynamics of dilatant faults and fractures (co-organized) PICO session* Dilatant faults and fractures are ubiquitous crustal features that form major pathways for fluid flow, such as water, hydrocarbons, or magma, and consequently are of great interest for water and energy supply, geohazard assessment and geodynamics. However, little is known about their detailed structure at depth, their surface expression, and the transition of failure modes from dilatant to shear. Reasons for this lack of understanding is the enormous complexity of dilatant fractures due to the influence of parameters such as lithology, fault kinematics and mechanical stratigraphy. Therefore, the time and space evolution as well as the seismic hazard potential are largely unresolved. In this session we invite contributions addressing all aspects of dilatant faulting and fracturing. We aim to stimulate discussion by integrating geophysical and outcrop studies as well as analog and numerical modeling. We particularly invite studies on all scales focusing on analyses of surface processes, topography, fault/fracture geometry, poro-perm characteristics, fluid flux modeling, age dating or kinematic reconstruction. We aim at providing a forum for all disciplines concerned with the dynamics of dilatant faulting and fracturing to meet and discuss their views. -- __________________________________________________ Dr. Michael Kettermann Structural Geology, Tectonics and Geomechanics RWTH Aachen University Lochnerstraße 4-20, 52056 Aachen, Germany Room 314a +49 (0)241 80-98439 ######################################################################## To unsubscribe from the GEO-TECTONICS list, click the following link: https://www.jiscmail.ac.uk/cgi-bin/webadmin?SUBED1=GEO-TECTONICS&A=1
