********************************************************************* From: Edgardo Cañón-Tapia <ecanon@xxxxxxxxx> ********************************************************************* Dear All We would like to invite you to participate in the session that we are organizing to be held during the oncoming AGU 2009 Join Assembly in Toronto, Canada, May 24- 27 (the official description can be found at: http://www.agu.org/meetings/ja09/). V05: Ore Genesis and Volcano Instability Large mature composite volcanoes and their shallow basement are privileged loci of hydrothermal ore genesis. Such volcanoes become inherently unstable as they grow and mature. Hydrothermal activity inside the edifice is one of the main instability factors. Other factors of instability include the nature of the basement and the local tectonics. Re-equilibration of a highly unstable edifice might be achieved by both sudden (e.g. sector collapse and edifice failure) and gradual (e.g. volcano-basement interaction such as volcano spreading) processes. Both kinds of processes may have profound effects on the volcano hydrothermal system and related ore genesis. Unlike the relationship between edifice instability and tectonics, which has been the subject of many research efforts during the last two decades, the link between processes related to volcano instability and ore genesis remain poorly understood at present. We feel that this situation stems in part from the lack of communication existing between workers across the tectonics and ore- related communities. Noting that our session focuses on the interplay between ore genesis, volcano instability and tectonics in an interdisciplinary approach, contributions addressing wider topics at the fringes of volcanology, tectonics and ore genesis will be most welcomed.
