WORKSHOP ANNOUNCEMENT:
Surtseyan volcanism: shallow subaqueous explosive eruptions
Leaders: JDL White (Otago, NZ), BD Pauly (UC Davis, USA)
This workshop, sponsored by the IAVCEI Commissions on Explosive
Volcanism, Volcanogenic Sediments, and Volcano-Ice Interaction, will
focus on deposits of two well-preserved Quaternary surtseyan
volcanoes, each of which erupted in one of the extensive pluvial
lakes of the western USA. There are two primary targets. The first
is Pahvant Butte, in Utah, which erupted beneath ~ 80m of water in
Lake Bonneville and consists of a basal subaqueously emplaced tephra
mound capped by a fairly typical tuff cone. The second will be Black
Point volcano, erupted beneath ~200 m of water in the precursor to
Mono Lake, California. Side trips are intended to Tabernacle volcano
(Utah), Panum Crater (Mono Lake), and Ubehebe craters (Death Valley).
Topics to be addressed are: subaqueous explosive eruption processes;
primary subaqueous deposits from the eruptions; syn-eruptive
redeposition; post-eruptive reworking and sedimentation;
palagonitization and other alteration of young basaltic glass.
Dates: 1-9/10 October, 2007 (NOTE SHORT LEAD TIME!)
Travel: Workshop start/finish, Las Vegas, Nevada, which is well
served with direct flights nationally & internationally.
Cost: details of cost remain tentative, but are expected to be in the
range $800-1000 including food & lodging
Participants: 10-20
