influence of plume upwellings (more details below). <br>

<p class=""><b>Abstract:</b> <br class="">
</p>
<p class="">It is well known that mantle convection can be
explored explicitly in terms of the plate and plume mode. The
former is associated with the cold upper thermal boundary
layer, which is the lithosphere, and the latter with the hot
lower thermal boundary layer, which sources plumes. Convective
buoyancies associated with these modes are significant,
capable of driving plate motions. However, they need to be
contrasted with plate boundary forces. Oblique rifting and the
influence of magma highlight some of the difficulties in
understanding these forces. Continental rifts provide an ideal
setting to study the interactions of the plume mode and
evolving plate boundary forces as the rifting process
advances. Numerous<br class="">
observations of continental breakup since the Cretaceous are
well documented in the geological archives. They include
mapping continental dynamic topography, studying plate
kinematic changes, using thermochronological models and
petrological observables, and imaging deep structure by
seismic tomography to constrain the breakup history. These
observations allow one to track the expressions of past mantle
flow and further understand the dynamics of continental
breakup as the interplay of convective and plate boundary
forces.<br class="">
<br class="">
This session aims to provide a holistic view of the causes of
continental breakup. We welcome contributions from seismic<br
class="">
tomography, anisotropy studies, geochemistry, plate
kinematics, structural geology, and numerical models that
address questions surrounding mantle-lithosphere interactions.
Studies using a multidisciplinary approach are particularly
encouraged.</p>
