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.
