Dear Colleagues,
We want to draw your attention to the session Li, Be and B: advances in analysis
and implications for Earth and environmental sciences, which will be held
during the 32nd International Geological Congress (August 20-28, 2004, Florence,
Italy). This session is part of the general symposium on Geochemistry, and has the
code G04.02. It is sponsored by the International Mineralogical Association.
The capability of detecting and quantifying Li, Be and B in minerals has impressively
improved in the latest years due to advances in both analytical equipment and
procedures. These elements can be now accurately quantified in concentrations
ranging from ppb to tens of percent. They have been unexpectedly discovered in
many rock-forming minerals, and so their crystal-chemical behaviour and
petrogenetic significance are now being re-evaluated.
The aim of this symposium is not only to provide the latest information on our
capability to detect and quantify Li, Be and B in minerals, but also to understand
their crystal-chemical behaviour as a function of the physico-chemical conditions of
their geologic environment. This increasing amount of knowledge is expected also
to improve our geochemical understanding of petrogenetic processes in general.
Examples of other topics falling within the purview of the session are: (1) the
presence, concentration and isotopic ratios of Li and B in lavas and in glass
inclusions; (2) the presence of Li, Be and B at the ppb level in minerals from the
Earth crust and mantle, as well as in extra-terrestrial materials, and their resulting
significance as tracers of differentiation processes; (3) the presence and
concentration of Be in surface and ground water and in sediments, with implications
for the study of the human impact on the environment.
We wish to invite contributions from all the disciplines relevant to this complex
picture, with the hope to favour a better mutual understanding and a profitable
exchange of information. Oral and poster presentations are both welcome. The
deadline for abstract submission is January 10, 2004, and more detail can be found
at http://www.321gc.org/home.htm. However, we would be happy to learn directly in
advance of your interest to contribute to the session.
