Dear people involved in the cosmogenic fields,
The purpose of this message is to urge you to consider submitting papers to
the session "Application of cosmogenic nuclides to the study of Earth
surface processes: the practice and the potential" to be held during the
32nd International Geological Congress (General Symposium "Isotope
Geochemistry"; symposium number G11.5) in Florence (21-28 August 2004). You
will find some details about this symposium hereafter.
Sincerely yours,
Lionel Siame and Didier Bourles



SYMPOSIUM G11.5 - Application of cosmogenic nuclides to the study of Earth
surface processes: the practice and the potential

Concentration measurement of cosmogenic nuclides (3-He, 10-Be, 21-Ne,
26-Al, 36-Cl) produced by cosmic ray bombardment within surficial deposits
and exposed bedrocks has revolutionized the study of geomorphic processes
and landscape history. Indeed, the abundance of these cosmonuclides is
proportional to landscape stability and, under favorable circumstances, can
be used within surface rocks as a proxy for erosion rate or exposure age.
This symposium will cover a wide range of applications and methodological
issues. Cosmonuclides have indeed been used to date geomorphic surfaces in
order to evaluate tectonically-driven displacement rates, or to constrain
the climatically-driven emplacement of glacial and alluvial features. They
also have been used to investigate soil development in various
environments. Furthermore, they allowed to determine exposure ages and
erosion rates of bedrock surfaces, and to constrain catchment-wide erosion
rates from alluvial sediments. Nevertheless, the reliability of such
studies, and of any resulting correlation, depending directly upon the
accuracy and precision of the isotope production rates, continued efforts
based on clear understanding of the basic physics of the method have been
conducted.

Information of interest related to this event:

1) The First Circular of the 32nd International Geological Congress has
been posted on the web since June 2002: www.32igc.org

2) A specific web site will be dedicated to the session "Application of
cosmogenic nuclides to the study of Earth surface processes: the practice
and the potential": http://cosmogenic.free.fr/symp32.html

2) Please bear in mind that the SUBMISSION DEADLINE IS 30 NOVEMBER, 2003.
3) General Symposia include all areas of Earth Sciences. Each symposium
will consist of several sessions of oral presentations. Each session will
last approximately half a day, with ten oral presentations in the morning
and eight in the afternoon. Authors may submit abstracts for oral or poster
presentations to the 32nd IGC from June 01, 2003 to January 10, 2004
indicating two sessions in priority order. Each abstract must be submitted
by the person who is going to make the oral or poster presentation
(presenter). Each presenter can submit only one abstract for volunteered
oral presentations but there are no restrictions for invited oral
presentations. Of course, a person who is not the presenter may be
co-author of more that one abstract. There are no limitations on the number
of posters submitted. All abstracts must be submitted electronically. Only
the presenters who do not have internet access, can submit their abstract
on a paper form. Paper forms for the 32nd IGC can be obtained from the
Scientific Secretariat: Phone/Fax: +39 055 2382146,

4) The Second Circular, with the final list of the symposia and sessions
accompanied by the names of the session convenors, will be distributed by
mail in early Spring 2003. After this time, electronic submission of
abstracts will be possible up to the deadline in late November, 2003.
5) The Organizing Committee estimates that a number of participants between
5,000 and 10,000 will attend the Congress in Florence. 25-30 parallel
scientific sessions will be held daily from 21 to 28 August 2004, for a
total of 300-400 sessions. Because of the size of the event, the Organizing
Committee is unable to subsidise the convenors work and the invited
speakers, but a Geohost program has been funded, mainly to help individual
scientists from developing countries to attend the Congress by contributing
to their expenses.
