IAVCEI commission on arc volcanism:
A proposal from Jon Davidson
(University of California at Los Angeles)
Objective:
To foster interaction and communication between scientists with an interest in volcanism at subduction zones. This may range from volcanological issues (including hazards, and therefore with strong links to the commission on explosive volcanism) to more academic concerns such as the identification of source contributions to subduction related magmas, mass balancing fluxes across convergent margins, and evaluation of the role of such magmatism in the evolution of crust and mantle.
Activities
- Informal interaction. Provide a forum (through the internet, perhaps also with a hard copy news letter, such as the "LIP Reader") for
- dissemination of information (meetings, databases, other web sites, important developments/ discoveries/ publications) by organizers (see personnel below)
- discussion of scientific issues, through electronic bulletin board/ discussion group.
- Structured interaction. Organize meetings focused on aspects of subduction-related volcanism, both as special sessions at international meetings (IAVCEI, IUGG, AGU, EUG, GSA...) and as independent "workshop" style meetings (a model for which might be the forthcoming "State of the Arc" meeting in Adelaide, February 1997). The latter would ideally incorporate a strong field component and involve field trips and outcrop discussions. They could be combined with meetings of the Explosive Volcanism Commission, or the (concomitantly forming) Ocean Island Magmatism Commission, either through overlap or by complete integration.
- Serve as an advocacy group independent of funding organizations to develop and endorse research endeavors involving subduction related magmatism. In recent years meetings such as "MARGINS" in Austin, 1994 and "SUBCON" in Catalina, 1995 have brought together groups of scientists such as we would hope to target, to discuss what we know and hope to know in arc magmatism, and to propose collaborative research efforts.
Personnel
I am willing to volunteer as responsible for the commission for a few years, and have one or two colleagues willing to help me out. The commission could be managed much as other IAVCEI groups with a leader and secretary or co-leaders - and perhaps a steering committee. The latter would ensure international representation.
I understand that IAVCEI would rather have commission leadership which crosses international boundaries, and will propose leadership accordingly.
