T43H:
Tectonic, Magmatic, and Geodynamic Studies of Extensional Processes: Applications in Iceland and the Nubia-Somalia-Arabia Plate System I


Session ID#: 8278

Session Description:
We invite contributions focused on understanding tectonic, magmatic, and geodynamic processes during rifting at various stages in development with specific emphasis on case studies in Iceland and the Nubia-Somalia-Arabia plate system. Active extension and volcanism along the East African Rift System as well as the adjoining Red Sea and Gulf of Aden spreading centers provide archetypal environments with which to examine both incipient rifts and recently-established seafloor spreading centers. Iceland offers a unique opportunity to directly observe the subaerial mid-Atlantic ridge - a fully-developed spreading center. We welcome petrological, geochemical, and computational investigations of mantle plume dynamics, extension-related volcanism and volatile flux, and magma supply, generation, and ascent. We also welcome geophysical, geodetic, geodynamic modeling, and geological research to better understand lithosphere-asthenosphere behavior, localization of deformation, mantle structure, structural inheritance, strain partitioning between brittle faulting and sub-surface creep, interplay between faulting and magmatism, and time-dependent plate-boundary deformation.
