Colleagues,

We would like to draw your attention to the following session on Tephra
Studies and Tephrochronology that will be convened at the 2008 IAVCEI
General
Assembly in Reykjavik, Iceland.  We especially encourage participation of
those who integrate such tephra studies with understanding eruptive
histories of  volcanoes. The abstract submission deadline is 1 April 2008,
and information on the submission process and the Assembly can be found at
http://www.jardvis.hi.is/page/i08-tinfo

This session will bring together scientists with active research interests
and significant expertise in the collection, analysis, and interpretation
of tephra deposits preserved in terrestrial soils, lacustrine deposits and
ice caps as well as marine sediments. Tephra horizons define
chronostratigraphic marker horizons of great precision and very extensive
distribution that are valuable dating and correlation tools in both
palaeoenvironmental and archaeological research. Decades of
tephrochronological studies have produced a number of high quality but
largely isolated data sets that if better integrated could have important
implications for a range of topics in the earth and environmental sciences.
The increasing interest across many organizational and disciplinary
boundaries in information about eruption frequency, volcanic hazard
analysis, palaeoclimate, palaeoenvironmental conditions, and other key
aspects of Quaternary history, underlines the importance of examining the
status of tephrochronology and to improve cross-disciplinary collaboration,
application, interpretation, and integration of results.


This session will focus on (http://www.jardvis.hi.is/page/I08-SYM2#2-n):
- Tephrochronology as a tool for understanding eruption histories of
volcanoes
- Documenting eruption frequency, magnitude and characteristics using
tephra fall deposits
- Geochronology and correlation of volcanic ash
- Innovations in data gathering protocols and analytical techniques
- Problems associated with interpreting tephrostratigraphy records
- Long-distance transport of volcanic ash
- The use of tephrochronology in palaeoenvironmental research
