A� Subduction and Collision Processes Through Time in the Mediterranean Area — From the Deep Mantle to the<br />
Surface (Session 27)<br />
The Mediterranean area is a classical natural laboratory for studying tectonic processes, from mantle exhumation and<br />
sea-floor spreading to subduction and collision. Its arcuate subduction zones and orogens delimit highly mobile microplates<br />
whose motions since the Early Mesozoic breakup <strong>of</strong> Gondwana have been intermittently independent <strong>of</strong> the overall<br />
relative motion <strong>of</strong> the Africa and Europe. Ophiolite belts <strong>with</strong>in these orogens mark the remnants <strong>of</strong> Tethyan ocean basins<br />
which can be imaged today as slabs in the mantle. Yet, the kinematics and dynamics that drive this anomalous microplate<br />
motion remain enigmatic. Understanding how the Mediterranean mountain belts are tied to microplate motion and mantle<br />
anomolies is key to assessing the role <strong>of</strong> deep-seated processes and their interaction <strong>with</strong> surface processes.<br />
We invite contributions on a wide variety <strong>of</strong> topics related to the evolution <strong>of</strong> Alpine-type mountain belts and subduction<br />
zones in the Mediterranean area. These will be treated in a single session lasting 2-3 days in order to encourage interaction<br />
between specialists <strong>with</strong> different approaches and viewpoints. Invited speakers are foreseen for subtopics relevant to this<br />
theme. Field trips in the nearby Alps will be <strong>of</strong>fered both before and after the meeting.<br />

B� Multi-scale Sedimentary Basin Dynamics (Session 9)<br />
Sedimentary basins are important repositories which allow geoscientists to reconstruct past climates, vertical surface<br />
motions, fluid flow, as well as lithosphere and mantle dynamics over geologically long timescales. With increasing availability<br />
<strong>of</strong> large scale data sets, computational power, and improved data infrastructure, large resources for new approaches<br />
in integrated and dynamic basin modelling exist, allowing to cross traditional discipline boundaries and providing better<br />
opportunities to understand the complex spatio-temporal evolution <strong>of</strong> sedimentary basins. This session aims to bring<br />
together colleagues both from academia and industry who are involved in reconstructing basin evolution at mega-regional<br />
to local scale. We invite contributions from:<br />
• Advances in linking deep-Earth dynamics and sedimentary basin architecture<br />
• Integrating plate kinematic models and lithospheric deformation in basin formation and evolution models<br />
• Linking regional- to basin-scale tectonics, including basin inversion<br />
• Coupled lithosphere deformation - petroleum systems models<br />

C� Significance <strong>of</strong> Large Strike-slip Fault Systems — Active and Ancient� (Session 14)<br />
Large strike-slip faults may accumulate large displacements, show high deformation rates and have been the loci <strong>of</strong> several<br />
<strong>of</strong> the largest (M 8) earthquakes in continental lithosphere on record. They may create both sedimentary basins and fold<br />
& thrust zones. Often, big cities are located near them, such as Los Angeles, San Francisco or Istanbul, implying high<br />
seismic hazards. A number <strong>of</strong> widely debated questions include their seismic potential, their total displacement, and their<br />
geological significance in ancient plate boundary settings. Recent developments in active tectonics, tectonic geomorphology<br />
and satellite geodesy have produced a significantly improved data base <strong>of</strong> deformation-related parameters, but not all<br />
questions can be answered by studying active faults at the earth’s surface. For example, it is difficult to quantify the surface<br />
strain budget attributed to individual fault strands, because strike-slip faults are <strong>of</strong>ten closely spaced, so that space-geodetic<br />
surveys can only capture the bulk deformation across a fault zone.<br />
For this reason, and many others, we need to understand the behavior <strong>of</strong> large strike-slip faults through study <strong>of</strong> both,<br />
active and ancient fault systems. This session solicits contributions from a wide range <strong>of</strong> aspects such as neotectonics and<br />
tectonic geomorphology, geodesy, deformation mechanisms, syntectonic metamorphism, thermochronology, as well as<br />
regional tectonics and palaeogeography. In particular, we solicit contributions from well studied strike-slip fault systems<br />
around the world, such as the San Andreas, the North Anatolian, the Altyn Tagh, the Kun Lun fault systems as well as<br />
large strike-slip faults <strong>of</strong> the Variscides and the Caledonides. We welcome field studies, experimental work and numerical<br />
modeling as well as review papers.<br />
