Abstract
Summary
Deformation bands are narrow tabular zones mm- to-cm thick, which can accommodate shear and/or volumetric strain by means of gran rearrangement, consequent pore collapse, and cataclasis. These structural features are very common in clastic sediments, but they can form also in granular carbonate media. Deformation bands can represent buffers for cross-flow and may cause compartmentalization or decrease in productivity of hydrocarbon reservoirs. This contribution presents an overview of the literature on carbonate-hosted deformation bands, compares them to the clastic hosted deformation bands and highlights the main differences between natural and laboratory deformation bands
