AGU special session

[Tim Barrows]

ANNOUNCEMENT:

We would like to draw your attention to a special session (SE26) titled :

NEW AND DEVELOPING GEOCHRONOMETRES AND THEIR FUTURE ROLE IN MEASURING 
LANDSCAPE EVOLUTION: INTEGRATING COSMOGENIC NUCLIDE, APATITE 
THERMOCHRONOLOGY AND LUMINESENCE TECHNIQUES

that will be conducted at the American Geophysical Union Western Pacific 
Geophysics Meeting in
Wellington, New Zealand from July 9-12 , 2002. A full description of this 
special session is
attached below and can be located at http://agu.org/meetings/wp02Sessions.html
<http://agu.org/meetings/wp02Sessions.html>

We invite abstracts across the spectrum of earth science applications that 
use, integrate or
demonstrate the potential of these geochronological techniques in landscape 
evolution (denudation,
glacial geomorphology, sediment burial, etc ) and also those related to 
calibration such as in U-Th
/14C chronology in corals. Depending on the number of abstracts, we plan to 
allow for extended
presentations and conclude with an open forum discussion on the potential, 
the benefits and the
limitations of integrating these techniques. We hope to secure funding to 
host one or two invited
speakers to set the background for this special session.

The deadline for abstract submission is only 3 weeks away ( 15th March) for 
postal / express mail
abstracts and 4 weeks ( Mar 22nd ) for email submission of abstracts (use

Tool Box on http://www.agu.org/meetings/wp02top.html

************************************************************************************************* 

Over the past decade the arsenal of tools in the field of isotope 
geoscience has experienced an
unprecedented rise in analytical and technological innovation. Our need to 
document and measure
changes of Earth's surface systems over ever wider spatial and temporal 
scales has also intensified
as we seek a more robust understanding of Earth's recent history.

The expansion of applications using in-situ cosmogenic radionuclides 14C, 
10Be, 26Al, 36Cl, and the noble gases, 3He and 21Ne, has redefined the 
level of quantification we can expect - both temporal and spatial - of 
earth surface process during the Plio-Quaternary epoch. Integration of 
these new and emerging capabilities with established methods such as OSL, 
U-Th series, Ar-Ar and 14C dating and fission track and U-Th/He apatite 
thermochronology, has the potential to revolutionise our ability to address 
fundamental questions concerning the evolution of the Earth's surface.

Papers that emphasise integrated or multi faceted approaches to using 
in-situ produced cosmogenic
nuclides to study the Earth's recent history are particularly encouraged, 
as are studies with a
Southern Hemisphere focus. Innovative sample preparation procedures, new 
applications and production rate calibration studies are also welcome
