The subject of this conference is the localization of deformation in rocks , with especial emphasis on shear zones as a physical expression of strain localization in orogens at the level of the middle and lower lithosphere. In the last two decades, there have been important advances in laboratory and numerical modelling studies of the way that deformation localizes in the Earth’s crust. An aim of the conference is to juxtapose the results of new theoretical, analytical, and laboratory research with the natural world relationships that may be observed in the exemplary field setting of Cap de Creus, northeastern Spain. The conference will offer the opportunity for researchers who employ the different approaches (theory; experimentation; seismological, petrological and field methods) to integrate results, address controversies, and identify new opportunities for interdisciplinary research that will advance our understanding of localization of deformation in shear zones at multiple scales.
The conference, of 6 days duration, is planned to have invited and contributed lectures and poster sessions that alternate with field trips. The charming village of Cadaqués is the conference location, because it allows ready access to shear zones and other strain localization structures in what is recognized as one of the best natural laboratories in the world: the Cap de Creus peninsula . Over a comparatively small area, there is access to structures that will allow the Penrose participants to observe and discuss the geometry, kinematics and mechanics of shear zones; triggers and mechanisms for folding and boudinage and development of kink bands, shear bands and brittle fractures; the influence of rigid vs. deformable objects in shear zone localization; and the role and interaction of fluids, melts and metamorphism.

• Insights on the role and interaction of fluids, melts and metamorphism in strain localization
• Physical and numerical experiments of strain localization
• Interdisciplinary approaches to the study of strain localization in orogens
