Thread: AGU Session: Structure and Evolution of the Oceanic Lithosphere and Mantle

Dear colleagues,

We invite your contributions to the AGU Fall Meeting 2020 session on the
structure and evolution of oceanic lithosphere and mantle. Feel free to
send us an email if you have any questions.

*Title:* DI017. Structure and Evolution of the Oceanic Lithosphere and
Mantle

*Description:* The structure and dynamics of the oceanic lithosphere and
underlying mantle are important for understanding Earth evolution. Data
from marine environments are sparse; this sampling problem has limited our
understanding of fundamental solid-earth processes on a range of scales,
including the causes of localized submarine volcanism, generation of
lithospheric fabric, evolution of hotspot tracks, and nature of
global-scale mantle convection. This session aims to showcase the cutting
edge in observations and modeling of the oceanic mantle. Marine geophysical
experiments provide new constraints on mantle seismic and electromagnetic
structure, volcanism and seismicity, seafloor deformation, and mantle
discontinuities. Computational and analogue modeling advances address
intra-plate geodynamics, variations in volatiles and rheology,
characteristics of mantle flow, and chemical and physical interactions from
the ocean to the deep mantle. By bringing together these recent insights
from the distinct observational and modeling perspectives, this session
hopes to foster synthetic understanding of the oceanic mantle.
