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 ============================================================== To unsubscribe from the volcano list, send the message: signoff volcano to: listserv@xxxxxxx, or write to: volcano-request@xxxxxxxx To contribute to the volcano list, send your message to: volcano@xxxxxxxx Please do not send attachments. ==============================================================
