This year the AGU is involved in organizing "The Meeting of the
Americas", which will be held in Foz do Iguaçu, Brazil, 08–13 August
2010 (see: http://www.agu.org/meetings/ja10/ ). We draw your attention
to a Union session (U14) "Thermal Regimes and Orogenesis from Archean to
Present." A description of the session is given below. The abstract
deadline is 31st March (see:
http://www.agu.org/meetings/ja10/program/abstract_submissions.php ).
Attendees at this meeting will have the opportunity to contribute two
abstracts and thus take advantage of being involved in more than one
session. We hope that the topic of our session and this early
invitation will enable you to include the Meeting of the Americas in
your plans for August.
Thanks,

U14: Thermal Regimes and Orogenesis from Archean to Present
Description: Accretionary and collisional orogens are associated with
contrasting styles of metamorphism, and some orogens both ancient and
modern display high thermal gradients that led to anatexis at shallow
depth and to a low cooling rate suggesting an almost stable thermal
structure over tens of My. Understanding secular evolution of mantle
temperature, orogenic thermal gradients, cooling rates and their effects
on the rheology of orogenic domains is critical to constrain geodynamic
regimes. The session will advance understanding of metamorphic and
orogenic processes by integrating data and models from field studies,
geochemistry, geochronology, geodynamics, geophysics, petrology and
tectonics.
