We would like to note the following session at the 2007 EGU meeting in Vienna, Austria (15-20 April, 2007): TS6.2 Continental wrench systems from top to bottom Continental wrench systems are lithosphere-scale structures that can be examined from top to bottom using geological and geophysical methods in active and exhumed orogens. This session will examine highly oblique tectonic regimes (wrench, transpression, and transtension) over a wide range of depths and time scales to explore the localization of geomorphic, deformational, and thermal processes. We invite contributions from field studies (tectonic geomorphology, active tectonics, brittle and ductile structural geology, metamorphic geology, thermochronology, etc.), geophysical investigations (crust and mantle anisotropy, etc.), as well as modeling and experimental approaches to discuss the dynamic feedbacks that may exist among processes from the surface to the mantle.
