Future activities
Plans for the future include workshops in the Andes (ignimbrites and debris
avalanches), in SE Australia (water-magma interaction), and in Italy
(shallow submarine volcanism).
Plans for activities at the IAVCEI International Volcanological Congress
1998 (Magmatic
Diversity: Volcanoes and their Roots) in South Africa are presently
being developed, with a planned symposium on the relationship between
kimberlites, maars, and diatremes.
Announcement of CEV Symposium at South Africa IVC Meeting
Kimberlites, Maars, and Diatremes
For decades, there has been considerable debate about the relationship
between kimberlites, maars, and diatremes. Evidence of the involvement of
phreatic water in maars became quite strong by the early 1970's, but do
kimberlites and diatremes all form through phreatic and phreatomagmatic
explosions? Also, what about the common association of CO2-rich magmas with
maars and diatremes? This symposium is proposed to provide the opportunity
for workers in this area to debate the processes involved in these
volcanoes, and the similarities and differences between them. We intend to
allow time for general discussion of the issues at the end of each session.
CEV Field Workshop Proposals for July 1999 in United Kingdom
from Mike Branney and Peter Kokelaar
We are considering the possibility of organising a field-based CEV
workshop, to run before or after the
July 1999 IUGG meeting at Birmingham, England:
(1) Inside silicic calderas. A 10-day field workshop visiting Snowdon
caldera in Wales, Scafell caldera in the English Lake District, and Glencoe
caldera in Scotland. These calderas have been uplifted and deeply eroded,
beautifully exposing their internal structure, caldera faults, conduits,
ignimbrite fills, and underlying caldera floors, such as are generally
obscured at modern calderas. Themes of the workshop would include (i)
nature and controls of contrasting styles of collapse; (ii) discrimination
of tectonic influences; (iii) processes and products of hydrovolcanism in
flooded calderas; (iv) controls on emplacement of lava-like ignimbrite
lithofacies in intracaldera settings; (v) role played by intrusion in
caldera fills.
(2) An alternative 8-day workshop would consider sedimentation associated
with major explosive eruptions in marine, volcanic island, caldera lake and
alluvial settings, at Scafell and Snowdon calderas.
We estimate that the 10-day workshop would cost about US $800, for return
transport from the Birmingham IUGG meeting venue, field transport, and
simple hotel accomodation. Both workshops would involve strenuous walking
in rough terrane, and informal evening seminars, for no more than 30
participants.
If you might be interested to participate in either workshop, please email
Mike Branney at mjb26@le.ac.uk as
soon as possible but no later than mid March. Please state your specific
interests and your preferences as regards timing in relation to the
Birmingham meeting, so that we can gauge if there is sufficient initial
interest to proceed.
