Description and Objectives
The subject of this conference is the localization of deformation in rocks, with special emphasis on shear zones as physical expressions of strain localization in orogens at the level of the middle and lower lithosphere. In the past two decades, there have been important advances in laboratory and numerical modeling studies of the way that deformation localizes in Earth's crust. These are accompanied by advances in imaging of lithospheric structure, including the distribution of fluids and melts, using seismological techniques that provide access to the depths of active tectonic zones. Innovative new techniques in thermochronology aid our understanding of the temporal evolution of the crustal scale zones of strain localization. An aim of the conference is to juxtapose the results of new theoretical, analytical, and laboratory research with the natural world relationships observed in the exemplary field setting of Cap de Creus, northeastern Spain. The conference will offer the opportunity for researchers who employ different approaches (e.g., theory, experimentation, seismological, petrological, and field methods) to integrate results, address controversies, and identify new opportunities for interdisciplinary research to advance our understanding of localization of deformation in shear zones at multiple scales.
This six-day conference will include alternating field trips and presentations (invited and contributed lectures and poster sessions). The charming village of Cadaqués has been chosen as 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 on the peninsula, 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 versus deformable objects in shear zone localization; and the role and interaction of fluids, melts, and metamorphism. Another aim of the meeting is to bring about greater integration of the results of contemporary physical and numerical investigations with the field observations of strain localization in orogens.
Now is an opportune time to place the heightened understanding from theoretical and quantitative approaches into juxtaposition with direct field observations that offer “ground truth” for interpretation of the combination of factors that lead to localization of deformation within shear zones. The principal proposed topics for presentation of laboratory, theoretical, and field studies are
- Shear zones: new perspectives on geometry, kinematics, and mechanics;
- Field, numerical, and analog modeling of mesoscopic elements of shear zones: folding and boudinage, kink bands and shear bands, and rigid and deformable objects;
- Insights on the role and interaction of fluids, melts, and metamorphism in strain localization;
- Physical and numerical experiments of strain localization; and
- Interdisciplinary approaches to the study of strain localization in orogens.
