TS6.3/GD6.4/SM2.15 – Formation and reactivation of small oceanic domains and hyperextended rift basins (co-organized)
Convener: Patricia Cadenas
Co-Conveners: Gabriela Fernández-Viejo, Gianreto Manatschal, Tim Minshull, J. Kim Welford
Confirmed invited speaker: Gwenn Péron-Pinvidic (Geological Survey of Norway)
http://meetingorganizer.copernicus.org/EGU2018/session/27978
This session aims to bring together studies which deal with the structure and the tectonic evolution of small oceanic and hyperextended rift basins using geological, geophysical, geochemical, and numerical modelling approaches. Analysis of the crustal structure, the sedimentary infill, the subsidence history and the thermal evolution allows us to understand better the evolution of these basins and the associated rifting, breakup processes and the influence of rift inheritance on their subsequent compressional reactivation due to stress field changes.
Please, inform your colleagues and students that may be interested in presenting their research in this session.
Looking forward to your contributions and to meeting you in Vienna
The conveners
Patricia Cadenas (U. Oviedo), Gianreto Manatschal (U. Strasbourg), Tim Minshull (U. of Southampton), Kim Welford (Memorial U. of Newfoundland) and Gabriela Fernández-Viejo (U. Oviedo)

GD2.1/GMPV8.1/SM4.07 – Geodynamics of continental crust and upper mantle, and the nature of mantle discontinuities (co-organized)
Convener: Lev Vinnik
Co-Conveners: Hans Thybo, Alexey Shulgin
http://meetingorganizer.copernicus.org/EGU2018/session/26531
We invite, in particular multidisciplinary, contributions which focus on the structure and evolution of the continental crust and upper mantle and on the nature of mantle discontinuities. The latter include, but are not limited to, the mid-lithosphere discontinuity (MLD), the lithosphere-asthenosphere boundary (LAB), and the mantle transition zone, as imaged by various seismological techniques and interpreted within interdisciplinary approaches. Papers with focus on the structure of the crust and the nature of the Moho are also welcome. Methodologically, the contributions will include studies based on seismic, thermal, gravity, petrological, and/or electro-magnetic data interpretations.
Instructions for submitting an abstract can be found at: https://www.egu2018.eu/abstract_management/how_to_submit_an_abstract.html
We hope that you have the opportunity to give a presentation at the upcoming EGU in Vienna 8-13 April.
Best regards,
The convenors: Lev Vinnik, Alexey Shulgin and Hans Thybo

Tectonic processes occur at a variety of timescales, from seconds (coseismic) to weeks (short-term slow slip) to years (postseismic and long-term slow slip) to decades (interseismic) to millennia or longer (long-term deformation). Studies focused on results derived from a single technique may not have sufficient context to assess how deformation evolves over time. In order to address this important problem, we invite contributions in which results from multiple techniques are combined to explore tectonic deformation over multiple timescales. We also encourage contributions that compare present to past behavior or that focus specifically on variability of tectonic deformation over long timescales.

SE29 – Understanding Active Volcanoes Using Multidisciplinary Approaches
Convener: Clara Solaro
Co-Conveners: Helena Albert-Minguez, Fidel Costa, Paul Okubo, Yosuke Aoki

Asia and Oceania present regions with the highest concentration and number of active volcanoes on Earth. Many of them are capable of large explosive eruptions, producing high eruptive plumes or pyroclastic density currents. Tephra material can thus be spread over considerable distances and affect human settlements over large areas and/or long timescales, which makes studies of these volcanoes even more important.
A large panel of data and observations on the activity of these volcanoes should allow greater constraint of their eruptive systems. In particular, it is important to unravel the link between volcanic plumbing systems and the resulting eruption dynamics. Geophysical methods (seismology, deformation, infrasound), geochemical monitoring (gas emission, hydrothermalism), petrology/mineralogy studies and physical modelling are all valuable means for acquiring a better understanding of volcanic systems and processes. However, combining multiple areas of study on the same target (e.g. petrology with seismology or gas emission data) is key to significantly improving our understanding of volcanic systems.
In this session, we will explore the state-of-the-art of on-going research focusing on studies of magmatic plumbing system structure and dynamics that use a multiple (e.g. petrological plus geophysical) approach. We appreciate contributions from volcanological field and lab observations, as well as modelling and experimental results. We aim to foster the use of interdisciplinary approaches for the study of volcanic processes, representing progress toward possible interpretations of signs of unrest in terms of causal subterranean plumbing system process.
We hope you consider submitting an abstract and attending the conference.
