Dear Colleagues:
We are convening a special symposium at Goldschmidt 2005 entitled
"Geochronology of Tectonic Processes." This session will focus on new
geochronologic approaches and observations on the timing, rates,
kinematics, and dynamics of tectonic processes. Examples include the use
of radiogenic and cosmogenic isotopes to understand the dynamics of
faulting, pluton emplacement, lithospheric flow, coupling of erosion and
deformation, metamorphic events, and detrital records of orogenesis.

This promises to be an exciting session highlighting state-of-the-art
techniques, approaches, and observations. Keynote speakers in this session
include Brad Hacker (UCSB), Mark Harrison (ANU), and Kip Hodges (MIT), and
confirmed invited talks will be given by Gary Ernst (Stanford), Mike Cosca
(Lausanne), and Dave Foster (Florida).

We would like to encourage submission of abstracts and your participation
in this session. The abstract deadline is 15 January 2005.

The 2005 Goldschmidt meeting (20-25 May) is shaping up to be an impressive
meeting. The program and list of people involved can be seen at the
website:

More detailed description of SS-33: Geochronology of tectonic processes:
Peter Reiners (Yale) and Randy Parrish (Leicester):
Improvements in both analytical techniques and interpretative contexts and
modeling capabilities, as well as development of new dating methods, have
recently inspired new insights into the timing, rates, and kinematics of a
variety of tectonic processes in continental and oceanic settings.
Examples include using thermo- and geochronology of radiogenic and
cosmogenic isotopes to understand the dynamics of low-angle normal faults,
uplift in transpressional settings, pluton emplacement, tectonic
"aneurysms," lithospheric flow paths in orogenic wedges, the
tectonothermal dynamics of thrust faulting, and the detrital record of
long-term orogenic histories. This session will focus on new approaches
and new observations on using geochronology (s.l.) to understand these and
other tectonic processes.

Sincerely,
Peter Reiners and Randy Parrish
