Dear All,
today is the deadline for abstract submission to
the next EGU meeting in Vienna and we encourage you to submit
an abstract to the following session:
"TS5.1: Failed vs. successful rifts: mechanisms for rift evolution"
http://www.cosis.net/members/meetings/programme/view.php?p_id=255
Keynote Speakers include Cindy Ebinger, Laurent Geoffroy, Gianreto
Manatschal
Description of session:
Not all continental rifts eventually evolve to the stage of continental
breakup. The so-called 'failed' rifts were once loci of strain
localization and crustal extension, but are now no longer considered
active. Other rifts proceed more successfully to their final stage and
result in continental separation and seafloor spreading with oceanic
crust formation. Why are some rifts successful, while others fail? Aim
of this session is to explore mechanisms that control rift development,
and are responsible for failure or success of a rift zone. The session
focuses on all stages of rift development: from the onset (and ending)
of continental extension to the formation and evolution of rifted
margins.
Examples of topics that we would like to address include the role of
magma injections during rifting, mantle plumes & mantle heterogeneities,
lithosphere rheology and deformation mechanisms, inherited weaknesses,
passive vs active rifting, and far-field plate boundary forces.
Welcome are data and models on failed and successful rifts, ancient and
modern passive margins (such as Atlantic margins, exposed margins of the
Alpine Tethys), but also for example the East African Rift System, which
is of special interest to the topic since, along its length, all the
different stages of the rifting process -from rift initiation to
continental breakup- can be identified.
We hope to see you in Vienna in April!
Kind regards,
Giacomo Corti
