The 2018 AOGS (Asia Oceania Geosciences Society) meeting will be held in
Honolulu, Hawaii on June 03-08, 2018. Here we solicit contributions to
the session SE32: Accretion and Subduction of the Oceanic Lithosphere,
from Ridge to Trench.

Session description: From its accretion at mid-ocean ridges to
descending at trenches, the structural and mechanical properties of
oceanic lithosphere govern its response to the underlying plate tectonic
processes. At mid-ocean ridges, the axial morphology and style of
faulting is controlled by the interplay between the tectonic and
magmatic extension, which are thought to reflect axially variable rates
of magma intrusion. Individual spreading segments are separated by
oceanic transform faults, which are mainly characterized by strike-slip
motion but release, on average, more than 80% of the cumulative moment
in aseismic creep. Along subduction trenches, thermal and
hydro-mechanical properties of the oceanic lithosphere can critically
affect the generation of earthquakes and tsunamis. It is critical to
understand the evolution of oceanic lithosphere in order to better
understand the associated geological and geophysical processes. In this
session we solicit contributions on all relevant studies on the
evolution of oceanic lithosphere, from ridge to trench, including but
not limited to, ridge accretion and axial morphology, axial faulting and
seismicity, slip and morphology along oceanic transform faults,
megathrust earthquakes, and subduction processes.
