We invite you to submit an abstract to our SEDI session on boundary layers and mantle plumes. Abstract submission closes August 3rd, 11:59pm EDT. Deep and Dynamic: the lower boundary layer, mantle plumes and their role in Earth?s mantle dynamics Abstract: Mantle dynamics at many scales is influenced by boundary layer processes. The bottom boundary layer controls plume generation and is dynamically linked to deep thermochemical features, such as LLSVPs and ULVZs, as well as to the outer core. Plumes rising from the bottom boundary layer sample the whole mantle and place their signature on Earth?s surface, providing insight into mixing of chemical heterogeneities and the state of the deep mantle. This session aims to explore the structure, mechanisms and dynamics of the deep mantle boundary layer including (but not limited to) the generation of mantle plumes, interactions with deep thermochemical structures, the dynamics of the outer core, and the resultant surface observations that might provide useful constraints on this region. We welcome theoretical, experimental, and observational contributions from geodynamics, seismology, geomagnetism, mineral physics, petrology, and other disciplines.

Our two invited speakers are Dave Clague, Monterey Bay Aquarium Research Institute Udo Barckhausen,BGR Federal Institute for Geosciences and Natural Resources It promises to be an exciting session. Please see the full session description below.** GP017: The Origin of the Hawaiian-Emperor Bend and its Implications for Plate Motions, Polar Wander, and Plate and Mantle Dynamics *Session ID#: * 13472 Session Description: The Hawaiian-Emperor Bend (HEB), which marks a 60? change in strike from the NNW-striking Emperor seamount chain to the WNW-striking Hawaiian chain, was first thought to denote a change in Pacific plate motion. It has alternatively been argued from global plate circuits that the HEB instead reflects a change in motion of the Hawaiian plume. The time near the bend may also be linked to an episode of true polar wander. Whether the Hawaiian plume migrates slowly or rapidly has profound implications for the structure and dynamics of mantle convection. Recent improvements to HEB geochronology, the geomagnetic reversal time scale, the recognition of volcanic events related a change in Pacific plate stress near the age of the HEB, new Pacific paleomagnetic poles, and timing and rates of spreading at Pacific plate boundaries bring evidence to change earlier interpretations. We encourage submissions on any and all topics related to the HEB.

Surface-interior coupling on Earth, Venus, and rocky exoplanets: influences on planetary evolution and habitability Venus and Earth display dramatically different geodynamical and tectonic regimes, with Venus lacking evidence for recent plate tectonics, despite having nearly the same size and bulk composition. These different tectonic regimes significantly influence cycling of key volatiles (including CO2, H2O, CH4, and O2) between surface and interior and thus long-term climate evolution. Climate may even play a role in dictating the tectonic regime. Furthermore, rocky exoplanets likely have a broader range of geodynamic outcomes with fundamental implications for volatile cycling and climate evolution on these planets. This session will bring together scientists studying Earth, Venus, and rocky exoplanets to explore the role of key variables such as mass, composition, temperature, atmospheric interaction, and volatiles on tectonic and geodynamic processes, the role of tectonic regime and interior dynamics on volatile cycling and climate evolution, and to compare planetary evolutionary pat hs within our Solar System and beyond. https://agu.confex.com/agu/fm16/preliminaryview.cgi/Session14096 Invited authors: Cedric Gillmann Cin-Ty Lee Conveners: Brad Foley (Penn State) Bob Grimm (Southwest Research Institute) Laurent Montesi (U.

If you're interested in studying sedimentary basin as an archive and indicator for orogenic evolution, please consider submitting an abstract to the session below, for the AGU Fall Meeting in San Francisco, 12-16 December 2016. Please note that the deadline is 3 August, 11:59 P.M. EDT. Session T031: Sedimentary basin records of convergent orogenic systems. Despite recent advances in understanding convergent orogens and sedimentary basins therein, the connections between the lower lithosphere and crust to the Earth's surface remains enigmatic. Deposition, deformation, and exhumation of basin strata are the product of interactions among these diverse tectonic and Earth surface processes (e.g., erosion, depositional environments, dynamic topography, magmatism, lithospheric flexure, and delamination) and provide insights into resulting orogenic, topographic, and regional environmental evolution. We invite contributions that study sedimentary basins from modern and ancient convergent orogens that utilize a range of field, laboratory, and modelling approaches. We aim to bring together interdisciplinary works that emphasize the use of multiple sub-disciplines, including but not limited to: sedimentology/stratigraphy, paleoclimatology, geomorphology, thermo-/geochronology, structural geology, palaeontology, and geodynamics. We particularly welcome studies that explore linkages between lower lithospheric to upper crustal and surficial processes, as well as coeval records from different basin types within a single orogenic system.

Sincerely, Bethany Chidester, James Wookey, Jasper Konter, and Maxim Ballmer ............................ Session Description: The lower mantle is an enigmatic and important region of the Earth, comprising a significant volume of the planet and driving much of the dynamics observed on the surface. For example, the lowermost layer of this region serves as a boundary between the iron-rich core and the silicate mantle. As such, it sets the heat flux out of the core, effectively regulating convection in the greater mantle and the generation of the geodynamo in the core. Additionally, the lower mantle serves as a graveyard for subducted slabs and as a region of plume generation, making its chemistry uncertain and heterogeneous. This session focuses on the dynamics and evolution of this region, including (but not limited to) seismic observations, high-pressure mineralogy and chemistry of relevant materials, dynamic simulations and geochemical models and observations through time.

With approx. 1180 employees, the GFZ is conducting interdisciplinary research on the ?System Earth? and the influence of humans on the planet. As a member of the Helmholtz Association, it is part of Germany?s largest science organization. This project is embedded in the vibrant Geodynamic Modelling Section with great expertise in numerical geodynamics ranging from mantle convection and plumes over lithospheric-scale processes to earthquakes and tsunamis. 1 Postdoc position (Geodynamics) Reference No. 51/25/16 D Project title: Structures and Dynamics of Magmatic Continental Rifts ? Numerical Modelling in two and three Dimensions The aim of this project is to understand the interaction of rift tectonics with the generation and extraction of magma. The successful candidate will use state of the art numerical modelling software in order to investigate magma-tectonic feed-back processes and their impact on rift dynamics in two and three dimensions. Focus regions comprise primarily the East African Rift System, but also the volcanic continental margins of the South Atlantic. The project is embedded in the Helmholtz Young Investigators Group CRYSTALS ?Continental Rift Dynamics Across The Scales: Understanding Observations Through Numerical Modelling?. It is carried out in cooperation with the research group ?General Geology? at Potsdam University. Tasks: - develop and run computational rift models - improve the geodynamic modelling software by introducing partial melting and melt extraction accounting for rheological feed-back processes - benchmark 2D magmatic rift models with well-studied areas of the Kenya Rift and the South Atlantic - application to 3D rift dynamics under consideration of rift segmentation and multi-phase extension - supervision of Master students Qualifications: - Master?s degree and PhD degree in geophysics, geology or other related disciplines at the time the position starts - research interest in continental rifting and numerical modelling - experience in scientific programming (e.g. C, Fortran, Python, Matlab, etc) - ability to work independently, as well as within a multidisciplinary team - research experience with the East African Rift System is a plus but not a must Starting date: - by arrangement Duration: - 3 years -------------- next part -------------- An HTML attachment was scrubbed...
