T013: Exploring the Characteristics and Dynamics of Oceanic Plates Entering Subduction Zones
Session ID#: 24328
Oceanic plates entering subduction zones play a key role in transporting material from Earth’s surface to the deep interior. In the last decade, several marine geophysical studies have revealed new high-resolution observations of bending-induced normal faults and additional structural variations suggesting infiltration of water into the crust and mantle of the downgoing plate. This session aims to highlight these findings as well as examine the relationship between large outer-rise earthquakes, megathrust events, compositional variations in the incoming plate and forearc, and the tectonic forces acting on the downgoing plate and the plate boundary interface. We also welcome presentations based on geophysical and geological studies of incoming oceanic plates, analyses of rock samples, effects of plate bending on the earth’s volatile cycle and igneous activities in the incoming plate, and numerical modeling studies that aim to elucidate the key tectonic processes within the incoming plate.
Conveners: Shuichi Kodaira (JAMSTEC), Douglas Wiens (Washington University in St Louis), Asuka Yamaguchi (University of Tokyo) and John Naliboff (University of California Davis)
T022: Integrated view of the Gulf of California and adjacent western Mexico and U.S.A. plate boundary: Tectonics, geophysics, structure, volcanology, petrology, stratigraphy and sedimentology, paleontology, geomorphology, geochronology, ore deposits and hydrothermal vents, and marine geology
Session ID#: 25313
The Gulf of California and the surrounding parts of western Mexico, and the Salton Trough and surrounding parts of the USA, form an ideal natural laboratory for studying a very broad spectrum of inter-related geological and geophysical processes. Prior AGU sessions have focused on particular aspects, such as tectonophysics or marine geology, but all of the topics listed in the title for this session can be better understood when considering advances in the other topics listed therein. The new venue for 2017 (New Orleans) can attract a broader spectrum of researchers than those that normally attend AGU. Now is the time to synthesize results in a multi-disciplinary session that will attract workers in all aspects of the geology and geophysics of the Gulf of California/Salton Trough and adjacent western Mexico and U.S. region. We solicit posters from a very broad base, and especially encourage interdisciplinary contributions.
Conveners: Cathy Busby (University of California Davis), Raquel Negrete-Aranda (CICESE National Center for Scientific Research and Higher Education of Mexico), Joann Stock (California Institute of Technology), and Paul Umhoefer (Northern Arizona University)
T037: Subduction Top to Bottom 2, with a Caribbean Flavor
Session ID#: 22904
From top-to-bottom, many geological, geophysical, petrologic/geochemical, and theoretical advances have been made toward understanding subduction zone processes and dynamics since AGU geophysical monograph “Subduction Top to Bottom” was published 20 years ago. This session and a related themed issue in GEOSPHERE are intended to revisit the issues that were explored in the 1996 publication and re-assess them in light of recent advancements as well as explore new discoveries and advances in subduction zone research. We invite the broadest possible range of contributions, including subduction-related hazards (volcanic eruptions, earthquakes and tsunamis) and resources, and we encourage contributions regarding Caribbean subduction.
Conveners: Gray E Bebout (Lehigh University), David W Scholl (USGS Geological Survey, Menlo Park), Robert J Stern (Univ Texas Dallas) and Philippe Agard (University Pierre and Marie Curie Paris VI)
T047: Transform Plate Boundaries: Mechanics and Hazards
Session ID#: 26428
Transform plate boundaries offer a window into the mechanical deformation of lithosphere absent of external mantle processes (corner flow, upwelling). Continental transforms also present significant hazards due to their proximity to population centers. A variety of deformation styles occur at transform plate boundaries, particularly at fault stepovers, endpoints, and in oblique zones. Recent ruptures of transform faults including the Kekerengu Fault of New Zealand and the Queen Charlotte Fault of western North America highlight the need for improved understanding of the mechanics and deformation processes associated with transform systems. We seek contributions highlighting new results from the recent Kaikoura earthquake and studies of the Queen Charlotte Fault, the San Andreas Fault, the North Anatolian Fault, and the Alpine Fault. We emphasize the importance of multi- and cross-disciplinary approaches to study transform systems and welcome broad contributions, especially research involving earthquake seismology, paleoseismology, marine geology and geophysics, tectonic geomorphology, and geodesy.
