8Faults can be either conduits or retarders for fluid flow. As the presence of 9 faults increases the risks for hydrocarbon exploration, the sealing behaviour 10 of a fault zone has been a focus for geological studies in the past 30 years. 11Due to the widespread occurrence of fault zones, either in extensional or 12 contractional regimes, knowledge about the fault sealing behaviour is of 13 great importance to a wide spectrum of disciplines in geosciences, for 14 instance, structural geology, geochemistry, petroleum geology, etc. 15Geologists have extensively study the sealing properties of a fault zone over 16 the last decades, ranging from fault zone architecture, fault seal types, fault 17 seal processes, fault rock classification, research methods and controlling 18 factors.

“…During the deformation of fault rocks, there can be two competing 270 compaction mechanisms which are the mechanical compaction and 271 chemical compaction (Fisher and Knipe, 2001). These two compaction 272 mechanisms affect fault rock properties depending on the clay/phyllosilicate 273 content of the host rocks.…”

“…Such bands are referred to as compactional shear bands (Fossen et al, 2007) or, combining their textural and kinematic characteristics, cataclastic compactional shear bands (CSBs). In addition, non-cataclastic bands with predominantly shear offsets are very common in the extensional regime, particularly where the burial depth at the time of deformation was low (<1 km) (Fisher and Knipe, 2001;Hesthammer and Fossen, 2001). A characteristic feature of sandstone deformation in the extensional regime is the tendency for deformation bands to cluster into zones that evolve into faults with deformation band damage zones (Antonellini and Aydin, 1994;Shipton andCowie, 2003, Johansen and.…”

International audienceContractional deformation of highly porous sandstones is poorly explored, as compared to extensional deformation of such sedimentary rocks. In this work we explore the highly porous Aztec Sandstone in the footwall to the Muddy Mountain thrust in SE Nevada, which contains several types of deformation bands in the Buffington tectonic window: 1) Distributed centimeter-thick shear-enhanced compaction bands (SECBs) and 2) rare pure compaction bands (PCBs) in the most porous parts of the sandstone, cut by 3) thin cataclastic shear-dominated bands (CSBs) with local slip surfaces. Geometric and kinematic analysis of the SECBs, the PCBs and most of the CSBs shows that they formed during ∼E–W (∼100) shortening, consistent with thrusting related to the Cretaceous to early Paleogene Sevier orogeny of the North American Cordilleran thrust system. Based on stress path modeling, we suggest that the compactional bands (PCBs and SECBs) formed during contraction at relatively shallow burial depths, before or at early stages of emplacement of the Muddy Mountains thrust sheet. The younger cataclastic shear bands (CSBs, category 3), also related to E–W Sevier thrusting, are thinner and show larger shear offsets and thus more intense cataclasis, consistent with the initiation of cataclastic shear bands in somewhat less porous materials. Observations made in this work support earlier suggestions that contraction lead to more distributed band populations than what is commonly found in the extensional regime, and that shear-enhanced compaction bands are widespread only where porosity (and permeability) is high

“…In poorly consolidated sandstones at shallow burial on the other hand, deformation is dominated by non-cataclastic bands that generally have little influence on permeability (Fisher and Knipe, 2001;Fossen et al, 2007). Rath et al (2011) suggest that the reason for this difference may be that carbonates are able to accommodate strain by crystal plastic deformation (e.g.…”

a b s t r a c tDeformation bands in porous sandstones have been extensively studied for four decades, whereas comparatively less is known about deformation bands in porous carbonate rocks, particularly in extensional settings. Here, we investigate porous grainstones of the Globigerina Limestone Formation in Malta, which contain several types of deformation bands in the hangingwall of the Maghlaq Fault: (i) bed-parallel pure compaction bands (PCB); (ii) pressure solution-dominated compactive shear bands (SCSB) and iii) cataclasis-dominated compactive shear bands (CCSB). Geometric and kinematic analyses show that the bands formed sequentially in the hangingwall of the evolving Maghlaq growth fault. PCBs formed first due to fault-controlled subsidence and vertical loading; a (semi-)tectonic control on PCB formation is thus documented for the first time in an extensional setting. Pressure solution (dominating SCSBs) and cataclasis (dominating CCSBs) appear to have operated separately, and not in concert. Our findings therefore suggest that, in some carbonate rocks, cataclasis within deformation bands may develop irrespective of whether pressure solution processes are involved. We suggest this may be related to stress state, and that whereas pressure solution is a significant facilitator of grain size reduction in contractional settings, grain size reduction within deformation bands in extensional settings is less dependent on pressure solution processes.
