EGU 2013 - Call for Papers
Damien Delvaux, Giulio Viola, Klaus Reicherter and myself are inviting
contributions for session TS9.5 "Advances in paleostress/strain
reconstructions in tectonic studies : methods, applications,
perspectives" at the 2013 EGU General assembly (Vienna, 07 - 12 Apr
2013).
Stress states in the Earth?s crust are of fundamental importance, they
determine how rocks deform, how fracture and fold patterns develop and
how faults behave. In general, the access to ancient states -
paleo-stresses - is allowed by different methods that give mainly
reduced stress tensors, focusing on the direction of paleo-stress
axes, while only few provide differential stresses, and even fewer
both quantities.
The session aims at making the point on the advances in methods of
paleo-stress/strain analysis and evaluate how paleo-stress/strain
reconstructions contribute to tectonic studies, both in terms of
orientations and magnitudes. We also would like to discuss keys and
pitfalls in paleostress reconstructions, to move forward the
long-lived debate on stress vs strain vs kinematic interpretation of
fault slip data and other geological indicators, and estimate to what
extent paleo-stresses can be compared to modern stresses in terms of
distribution in time and space and of geological and physical
meanings. We would also like to tackle the need for new improved
techniques and the way existing ones can be more thoughtfully combined
and applied.
Our ultimate wish would be to bring together researchers who work on
these topics. We welcome a wide range of contributions :
methodological contributions, contributions that use
paleo-stress/strain analyses to decipher the regional polyphase
tectonic history, to better constrain fold kinematics and to improve
our understanding of reactivation mechanisms and strain partitioning
in the brittle regime, as well as modeling studies of stress states at
the local or regional scale.
Abstract submission deadline is 09 Jan 2013. In case you would like to
apply for support, please submit no later than 30 Nov 2012.

Please forward this call for papers to anyone who might be interested in
participating in such a session
Looking forward to seeing you in Vienna,
Sincerely
Olivier Lacombe
