Volcanism, and the continuous creation and subduction of oceanic lithosphere regulate the exchange rates of energy and material between the Earth’s interior and surface/atmosphere. Geophysical observations provide increasingly detailed constraints on flow patterns in the mantle. For instance, seismic anisotropy in tectonically active regions in the mantle, such as spreading zones or boundary regions, is most likely related to preferred alignment of crystallites caused by the prevalent tectonic stress. Furthermore, tomographic images of fast and slow seismic wave speeds in the mantle are often associated with descending slabs and ascending plumes. This interpretation, however, remains ambiguous as varying wavespeeds could be caused by factors such as anomalous temperatures, partial melting, deformation associated with high dislocation density, or the presence of water. A detailed interpretation of these large-scale geophysical observations in terms of mantle flow patterns therefore should be synergized with information about the physical and chemical properties, and behaviour of Earth’s materials under high temperature and pressure conditions in the laboratory or in computer simulations. In this session, we welcome contributions on the properties of mantle materials that relate to our understanding of material flow in the mantle. > > Invited Speaker: Ulrich Faul, MIT > > Submission is possible until 28.04.15 at http://www.geoberlin2015.de/abstracts.html > > Many thanks, > > Hauke Marquardt (BGI Bayreuth) > Robert Farla (BGI Bayreuth) > Patrick Cordier (Université Lille 1) > > > ------------------------------------- > Dr. Hauke Marquardt > DFG Emmy Noether-Research Group > www.depict-group.org/geomax > > Bayerisches Geoinstitut BGI > University of Bayreuth > 95440 Bayreuth, Germany > > Tel: +49 (0)921/55-3718 > Fax: +49 (0)921/55-3769 > Email: [log in to unmask] > -------------------------------------- > > > _______________________________________________ > MSA-talk mailing list > [log in to unmask] > http://lists.minlists.org/mailman/listinfo/msa-talk
