  Information - TS7.3 Material transfer at convergent margins

Event Information
Subduction zones are not only our planetís most dynamic regions but also of very great societal importance as regions with the highest hazard potential, large deposits of economic relevance, and attractive regions for human settlings. In recent years, much progress has been made in geophysically imaging the structures of subduction zones with higher resolution, and also understanding the processes at convergent margins with simulation and from their isotopic inventory. While this research and also the identification of first order parameters controlling convergent margin dynamics has been mainly made through investigating present site of subduction, it is also of highest relevance to aid the understanding of fossil subduction zones. On the other hand, crustal levels not directly assessable in present subduction zones are exposed in old orogens. The aim of this series of session is to bring together studies from different disciplines (geophysical imaging, process simulation, geochemistry, structural geology) and actual as well ancient sites of subduction.

Convergent margins can be sites of crustal growth as well as crustal destruction through sediment accretion or subduction erosion, respectively. Material transfer also is intimately linked with subduction zone hazard. Further, convergent margins are a site of e.g. accumulation of valuable hydrocarbons and ore deposits. To understand material transfer at convergent margins and its impact of other subduction zone processes needs truly interdisciplinary approaches. Therefore, we invite contributions from all fields of geophysics and geology dealing with both, accretive and erosive margins and also dealing with the marginsí economic geology.
