TEPHRATRACE

[Tim Barrows]

From: Chris Turney <c.turney at qub.ac.uk>

The Commission for Tephrochronology and Volcanism announce a 'virtual'
workshop on practical techniques for detecting, extracting and geochemically
analysing microscopic volcanic glass. The workshop is a new initiative
for the Commission as it will be presented via the Internet. It will be of
particular  interest to COTAV members and will also be freely available to 
members of
all INQUA Commissions. From 15th April 2002, by simply logging on to
the COTAV website 
(http://www.qub.ac.uk/arcpal/Tephra/Tephratrace/Home.htm), members will 
have access to activities which will detail the value of using microscopic
tephras for correlative purposes. Practical demonstrations on detecting, 
extracting and geochemically-analysing minute quantities of volcanic glass 
will be available and a case history
describing the value of the microscopic tephra to the Quaternary scientist 
will be
presented. Particular attention will be given to techniques used when
performing Electron Microprobe single-tephra shard analyses. To support the
Commission's international membership, the presentations will be made in
English with Chinese and Italian text available at the time of the workshop 
or soon
thereafter. Interactive sessions when Commission members may contact fellow
scientists for discussions will comprise a further aspect of the
workshop. No registration is necessary.

Best wishes,
Chris
