Strain localization occurs on all scales, from small
laboratory samples up to crustal fault zones. Since
localized deformation can significantly influence the
stress field, strain partitioning and fluid transport, it
is important to have a fundamental understanding of the
mechanics of strain localization in rocks. The interplay
between overburden-related boundary conditions and rock
rheology can be responsible for the development of
dilatant (i.e. joints and veins) and/or contractional
(i.e. compaction bands and pressure solution seams) strain
localization features.
The session aims to identify the microstructural
parameters that control the development and geometric
attributes of strain localization features at various
scales, from field to laboratory and on transport
properties. In particular new experimental techniques for
estimating the transport properties of natural media and
data interpretations will be analyzed.
