**** Apologies for multiple postings *****
Dear all,
The deadline for submission of abstracts to this session is approaching
FAST (July 13th) - and the session is filling up quickly. We would very
much like to encourage students working on low-angle normal faults to
get involved and present either talks or posters in this session. We
want to generate lots of discussion!
Please pass this message on....

Just to remind you all about the Topical Session T90 at the
Geological Society of America Annual Meeting in Denver, Colorado
November 7-10,
2004:
"Low-angle Normal Faults and Faulting: Field studies, Fault Rocks,
Mechanics and Weakening Mechanisms"
Convenors:
Bob Holdsworth, [log in to unmask]

In 1984, a seminal GSA meeting in Reno, Nevada was held where many of
the key concepts and datasets related to low-angle normal faults and
faulting were discussed. Twenty years later, the processes associated
with the development of these structures and indeed their very existance
as tectonically active features remains uncertain and controversial. In
what we hope will be an exciting and controversial session, we seek
contributions from a wide range of disciplines (field geologists,
experimentalists, seismologists, geodynamicists, and others) to present
observational evidence and theoretical insights concerning low-angle
normal faults and faulting.
John Dewey, Gary Axen, Mark Anders and Uwe Ring have very kindly agreed
to be keynote speakers at this session: provisional titles are given below.
We urge you strongly to submit and abstract for either an oral or a
poster presentation in this session!
The abstract submission DEADLINE is July 13th - information on the
submission process is available on the GSA webpage: www.geosociety.org
Please feel free to contact any of us if you have questions about
the session. We are looking forward to a lot of lively,
cross-disciplinary discussion!
Cheers,
Bob, Darrel & Cristiano
