    Strain localization structures such as fractures, stylolites, and deformation bands have important effects on reservoir performance but lack a consistent terminology. Advances in the recognition and interpretation of such structures now motivate a comprehensive framework that stresses their similarities instead of their differences. We review and assess the classical terms for localized ...

     · Compactive deformation bands (CDBs) are thin, tabular, bounded features of highly localized pore-loss compaction that commonly occur as systematic arrays in porous sandstone. Abundant field evidence from the Jurassic Aztec Sandstone of southeastern Nevada suggests that CDBs propagate and interact as brittle, closing-mode cracks in a nominally elastic medium.
