Porous media, including volcanic and clastic sedimentary materials, exhibit a wide range in mechanical and hydrologic
properties. The purpose of this workshop is to explore this range, with the goals of: 1) investigating physical
controls on fault-zone deformation; 2) quantifying the hydrologic properties of structures produced by different
deformation mechanisms; 3) utilizing fault-zone diagenesis as a record of fluid-rock interactions; and 4) developing
methods to effectively model flow and transport through faulted porous media.
The workshop will begin with a field trip to examine faults in the Bandelier Tuff, exposed in Bandelier and Kasha
Katuwe Tent Rocks National Monuments. In addition to beautiful scenery, the trip will allow us to explore a range in
fault-zone structures from fractures to deformation bands, and will set the stage for discussing the hydrologic implications
of the petrophysical and structural heterogeneity of faulted tuffs. The following two days will be divided between brief
sessions of short talks, poster sessions (posters will be up all day to facilitate discussion), and discussion sessions.
Potential topics for presentation and discussion include: 1) case studies, including structural, geochemical, and
hydrologic investigations of faulted porous media; 2) how to effectively incorporate qualitative geologic data into
quantitative hydrologic models; 3) upscaling of small-scale structural and hydrologic data; and 4) extrinsic (e.g.,
confining pressure, strain rate) versus petrophysical (e.g., porosity, cementation) controls on fault-zone deformation processes.
We will meet in the lovely Ghost Ranch conference center, downtown Santa Fe, which will limit the size of the
group to 50 participants, although we hope to attract a broad range of earth scientists. Please send letters of
application by July 1, 2003 to Deborah Rivera, Los Alamos National Laboratory, EES-IGPP, MS C305, Los Alamos, NM 87545
or drivera@lanl.gov (Phone 505-667-0920), including a brief statement of interests and relevance of the applicant's work
to the conference topic. A short abstract of work to be presented at the meeting may be included if desired. Graduate
students are encouraged to apply. Conference costs will be $335 for participants staying at Ghost Ranch in Santa Fe
(double occupancy; single occupancy dependent on availability, add $135 more) and $165 for locals who will drive to the
conference each day. The conference fee for those staying at Ghost Ranch includes three nights lodging, three meals a
day, snacks, and transportation during the field trip; commuter fee includes lunch each day, dinner Tuesday night,
snacks, and field trip transport. Round-trip airport shuttle will cost an additional $40. Limited funds will be
available to support some participants; applications should indicate the degree of need for such funds. Notification of
acceptance will be given by July 15, 2003; the deadline for registration is August 1, 2003. The final workshop agenda
and additional travel information will be provided to all registrants in late July and will be posted on this (the New
Mexico Tech Faults and Fluids Group's) web page at http://www.ees.nmt.edu/Geol/Faults/Faultsflow/igppworkshop.html.
