Dear All,
Please find the following announcement for a Penrose Conference as it will
appear in the forthcoming GSA Today. The topic is on three-dimensional flow,
fabric development and strain. The conference will also honor John Ramsay, who
recently had a milestone birthday.
The meeting will be held at Monte Verita, Switzerland next summer and will
comprise several days of presentations - hopefully accompanied by hot
discussions - combined with visits to spectacular nearby outcrops that are
relevant to the topic of the conference.
Prior to the conference we plan a 7 - 10 day field trip to examine the major
domains of the Western Alps of Switzerland and Italy. Costs for this trip
will
be held to a minimum especially to encourage graduate students to participate.
We invite interested individuals to submit an abstract for a
presentation/poster
at the conference before March, 15th 2002. Feel free to contact me or one
of the
co-convenors if you have further questions.
Best regards,
Hermann Lebit

*************************************************
A Geological Society of America Penrose Conference entitled
"Three-dimensional flow, fabric development and strain in deformed rocks
and the significance for mountain building processes: new approaches," will be
held August 18 - 24, 2002 in Ascona, Switzerland.
The major goal of the conference is to discuss new approaches to structural
geology and tectonics, focusing on the spatial and temporal complexities of
three-dimensional deformation processes. Potentially controversial topics will
be addressed, which should stimulate future discussion within the discipline.
Topics to be covered include a broad range of subjects and methodologies, from
large-scale views of lithospheric processes to the micro-mechanics at the
grain
scale of deformation. They include:
- the nature of heterogeneous strain fields in repeatedly deformed rocks as a
result of superposed folds or reactivated shear zones. How do strains
accumulate
in such systems and how does the state of finite strain correlate with the
development of structures and fabrics in these rocks?
- the significance of final structures and fabrics for the analysis of complex
deformation. Can rock structures and rock fabrics be used to track the
deformation path?
- the relationship between rock fabrics and finite or incremental strain.
How do
fabrics and textures behave under non-steady deformation, and is fabric
development cumulative, cyclic or does it reflect certain segments of the
deformation path.
- the scale dependency of structural analysis. Can we use outcrop-scale
information to interpret the regional kinematics, and are macroscopic
structures
controlled by local strain or by the regional background deformation?
- three-dimensional forward modeling of deformation systems. How can we
approach
the complexity of deformation paths arising from non-steady state conditions
and/or three-dimensional displacement fields? Which models are appropriate?
The conference is to be held at Monte Verita, a small ETH conference center
above Ascona, on the shores of Lago Maggiore (http://www.csf-mv.ethz.ch/),
where
nearby spectacular rock exposures will be studied in order to integrate direct
observations into our discussions. The Alps are an ideal environment for this
conference as these mountains represent one of the best documented geological
archives of a complex tectonic history which perfectly exemplifies the
conference topics. Three of the six conference days are reserved for field
trips
to different areas of the Alps relevant to the conference themes, The other
three days are devoted to lectures, poster presentations and discussions. The
Conference is being co-sponsored by the Swiss Geological Society, the Tectonic
Studies Group of the Geological Society and ETH Zurich.
The conference is limited to 80 participants. We encourage interested graduate
students to apply and some partial student subsidies will be available. The
registration fee, which will cover lodging, meals, field trips, and all other
conference costs, except personal incidentals, is not expected to exceed $850.
Participants will be responsible for transportation to and from the conference
site. Further information on travel will be provided in the letter of
invitation
but is also available at:
http://www.csf-mv.ethz.ch/official/travelinfo/travelinfo.htm All participants
will be encouraged to present posters and short notes on their current
research
related to the topics of the meeting and significant time will be given to
view
and discuss these.

The application deadline is March 15th, 2002. Invitations will be mailed to
participants by early April, 2002. Potential participants should send a letter
of application to Hermann Lebit (address above), including a brief
statement of
interests, the relevance of the applicant's recent work to the themes of the
meeting and the subject of any proposed presentation. Potential participants
should also indicate their interest in an optional, low cost (~$500),
pre-conference field trip. This one-week to 10 day excursion will transect the
major domains of the Alps exposed in Switzerland and Italy.
