IAVCEI General Assembly 2008
Volcanoes and Eruptions: Tephra Studies-Tephrochronlogy (session 2-n)

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-intro

Please forward this information to interested colleagues and we look 
forward to seeing you in Iceland!

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
