SEG-AGU Geophysics of Convergent Margins

12–14 July 2022 | Seattle, Washington, USA

About


The SEG-AGU joint workshop on Convergent Margins is an in-person workshop scheduled to take place over three (3) full days on 12–14 July 2022 at the University of Washington in Seattle, WA

The core objective of this workshop is to bring researchers from both the SEG and AGU communities working on the Geophysics of convergent margins. We expect a broad and diverse audience drawn from domestic and international researchers, including graduate students and early career scientists who are interested in the structure and dynamics of subduction zones. 

This workshop will include a half a day visit of the different facilities related to the study of subduction zones at the University of Washington and we may be able to organize an optional field trip to the Olympic Peninsula on 15 July depending on interest.  

Workshop Description

Convergent plate margins are important tectonic environments as these margins (1) host the largest and most destructive earthquakes and related tsunamis as well as the largest volcanic eruptions on Earth and (2) are accompanied by large onshore/offshore basins that are suitable for hydrocarbon preservation. They also represent natural laboratories to study fundamental cycles of the Earth System (e.g. carbon, water, etc.) and the fluid exchange between the Earth and the Ocean. Convergent plate margins are more challenging research environments due to their structural complexity and their dynamic evolution on short time scales. Over the last decade, the development of geophysical imaging and monitoring techniques as well as numerical and laboratory modeling have been proven useful to unravel some of the complexity of subduction zone processes.

This workshop aims at expertise exchange from different fields to improve the understanding of convergent margins as multi-faceted geological systems.  In particular, the steering committee is seeking presentations on the following topic areas: 

  • Geophysical imaging and time-lapse analysis of the convergent margin system at different scales
  • Tectonics and geology of convergent margins (e.g. forearc basin evolution, foreland domain)
  • Modeling of subduction zone dynamics
  • Cycling of the Earth system and fluid flow at convergent margins
  • Natural hazards and resources

Leaders/experts on each of the topic areas have been invited to present a keynote presentation at the beginning of each session.

 7 sessions (3 days)

Geophysical imaging of complex systems at different scales:  Geophysical imaging employing a wide range of methods (e.g. ground penetrating radar, electromagnetics, active and passive source seismic) is a powerful tool to reveal the complex structure of convergent margins from the near surface to hundreds of kilometer deep into the Earth, and has played a key role for our understanding of their dynamic processes. This session will showcase recent advances in geophysical imaging to illustrate structure and physical properties of convergent margins.

Time-Lapse Geophysics: Convergent Margins include many time-varying dynamic systems related to tectonic impact, subduction, obduction, faulting, earthquakes, volcanism, mountain building, basin formation, topography, hydrology, erosion and even climate change.  This session focuses on various time-lapse geophysical methods to observe, image, interpret and invert dynamic changes in convergent margin zones such as fluid and heat flow, pressure and stress propagation, and ground deformation via active and passive source seismology, interferometry, gravity, magnetics, EM, inSAR, geodesy and other geophysical methods.

Natural Hazards: Convergent margins bring associated hazards, the obvious ones including earthquakes and volcanic eruptions. However, perhaps as disruptive and impactful for risk are the associated cascading hazards such as tsunamis, ground failure and liquefaction. This session will address some of these hazards, and their relationship to insights gleaned from the geophysics of convergent margins.

Geophysics of convergent margins - Tectonics and Geology: This session will examine current and future directions of geophysical applications and research related to convergent margin tectonics and geology. Tectonic themes include; thrust wedge evolution, strain partitioning, and landscape evolution. Foreland and Forearc basin construction and their links to subduction zones will be covered; including, erosion and accretionary processes, sedimentary source, dispersal, and accumulation, as well as key stratigraphic elements. 

Modeling of subduction zone dynamics: Tectonic plate interactions, 3D mantle flow, and slab dynamics are just a few large-scale processes that influence the mechanics of convergent systems. Laboratory and numerical geodynamic models can be used to provide insight on how long-term and short-term tectonic forces affect such processes. This session explores how geodynamic modeling of subduction and collision are used for understanding the complex forces at play and how those forces affect the geology and geophysics at convergent margins. 

Cycling of the Earth system and fluid flow at convergent margins: 

Natural Resources: From hydrocarbons to geothermal to methane hydrates, convergent margins and their associated basins are rife with energy and mining resources that humans have needed in the past, and will still explore for in the future.  This session will focus on the myriad of natural resources that can be found in these unique geologic settings.

There will be an icebreaker held at the conference hotel in the afternoon of the first day for social interaction, at the conference hotel. In addition, there will be a campus tour at the University of Washington in between sessions on the third day. 

On the last day, there will be a fieldtrip to the Olympic Peninsula. Details are pending. If you are interested and available, please indicate your level of interest on your Abstract Submission form.

Keynote Speakers

Christine Chesley is a marine electromagnetic geophysicist whose interests include subduction dynamics at active margins, material properties of seamounts and transform faults, and the rheological evolution of oceanic lithosphere. Her research involves collecting seafloor electric and magnetic field data in order to model the resistivity of the lithosphere and mantle. She uses these resistivity models to detail the internal heterogeneity of seamounts, understand along-strike porosity variations at the Hikurangi subduction zone, characterize electrical anisotropy in oceanic lithosphere, and determine the nature of an earthquake rupture barrier at the GOFAR oceanic transform fault. Christine currently holds a postdoctoral position in Geology and Geophysics at Woods Hole Oceanographic Institution, Massachusetts.

Brian Horton is the J. Nalle Gregory Chair in Sedimentary Geology at the University of Texas at Austin and has a joint appointment with the Institute for Geophysics and Department of Geological Sciences in the Jackson School of Geosciences. His research addresses the tectonics of sedimentary basins and the evolution of orogenic systems, particularly the Andes of South America. He focuses on sedimentary basin development and utilizes sedimentology, stratigraphy, geochronology, structural geology, and geochemistry to understand modern and ancient sedimentation, river drainage patterns, sediment provenance, and mountain building.

Atsushi Noda is a Chief Senior Researcher with more than 20 years of experience working alongside the marine and onshore geological mapping projects in the Geological Survey of Japan. Atsushi specializes in sedimentary geology and is responsible for making geological maps using geological, theoretical, and experimental approaches, including basic field survey, core observation, seismic interpretation, analog sandbox experiments, and numerical simulations. His main interest is understanding processes of basin formation and sediment deposition along active plate subduction margins, especially forearc basins, in modern and ancient settings.

Invited Speakers

Suzanne Carbotte is Bruce Heezen Lamont Research Professor at the Lamont-Doherty Earth Observatory of Columbia University. She is a marine geophysicist who uses active source seismic imaging techniques and other geophysical methods to study dynamic processes at Earth’s tectonic plate boundaries and the linked magmatic, tectonic and fluid flow processes of oceanic crustal formation and evolution. Her current research includes high resolution studies of magmatic systems beneath fast and intermediate spreading mid-ocean ridges, the properties of oceanic crust within plate interiors and the architecture of subduction zones. In her presentation she will discuss results from a recent seismic imaging study of the Cascadia Subduction Zone.

Antoniette Greta Grima is a Post-Doctoral Fellow within the Institute of Geophysics and the Jackson School of Geoscience at the University of Texas at Austin. She is a computational Geodynamicist interested in understanding the links between deep subduction processes, slab dynamics and surface deformation.

Evan Solomon is an associate professor in the School of Oceanography at the University of Washington. He is a marine geochemist/geologist whose research combines the development of seafloor/subseafloor instrumentation, fieldwork, laboratory analysis, and numerical modeling to document and understand a wide range of marine geologic processes. His research is interdisciplinary, combining the fields of geology, geochemistry, geophysics, and microbiology. His current research focuses on 1) biogeochemical cycling between the ocean and crust; 2) fluid flow at subduction zones; 3) methane hydrate systems; 4) sediment diagenesis; and 5) metabolic pathways and rates in the deep biosphere.

Dr. Xin Zhou is a postdoctoral researcher at the Department of Earth and Environmental Sciences, University of Minnesota (Twin Cities). He is a geodynamic numerical modeler with a strong background in geology. He focuses on using numerical models to reveal the subduction initiation processes and to integrate them with geological observations. His current research is concentrated on understanding subduction initiation, including the weakening and healing mechanisms of the lithosphere deformation, propagation of preexisting subduction zones, subduction initiation nucleated at preexisting weak zones, and geological observations of subduction initiation. His research interests also include the subduction initiation in the early Earth and the onset of plate tectonics, subduction initiation on terrestrial planets, exploring subduction initiation from a global perspective, and metamorphism and fluid migration in mature subduction zones.
