“…Bedding dips at the sampling depths are also shown on Figure F1. Unfortunately, the deepest sample could not be tested successfully because of severe fracturing.Previous laboratory tests of natural clay-rich sediment and shale tend to show large ranges in permeability values because of differences in the material's mineral composition and texture (Bennett et al, 1989; Neuzil, 1994;Dewhurst et al, 1999; Yang and Aplin, 2007;Gamage et al, 2011). Of particular interest to our study is the anisotropy of permeability (e.g., Clennell et al, 1999, Bolton et al, 2000 because that property is likely to change in response to tectonic loading and fault-related deformation.…”

“…In subduction systems, the orientation of maximum principal effective stress and grain fabric may change because of tectonic loading and/or shearing. The hydrological properties of sediment, moreover, depend on many inherited factors, including grain size and shape, sorting, the type of geometric arrangement, and the magnitude of the interparticle forces (Moon and Hurst, 1984;Bennett et al, 1989Bennett et al, , 1991. Different scales of fabric also need to be taken into account (Mitchell, 1993).…”

In this study, we conducted constant-flow permeability tests in the horizontal (cross-core) and vertical (along-core) directions using five whole-round core specimens of mud(stone) from Integrated Ocean Drilling Program (IODP) Site C0001. The site is located above the accretionary prism of the Nankai Trough offshore of the Kii Peninsula, Japan. The samples came from depths of approximately 25 to 290 m below seafloor and include lithologic Units I (slope apron facies) and II (upper accretionary prism). Effective isotropic confining stress during the tests was set at five increments ranging from 0.034 MPa (5 psi) to 0.551 MPa (80 psi). Average values of hydraulic conductivity range from 1.06 × 10 -8 to 7.30 × 10 -7 cm/s. Corresponding values of intrinsic permeability range from ~10 -17 to 10 -16 m 2 . The ratio of horizontal to vertical permeability (k h /k v ) averages 1.15. Environmental scanning electron microscopy was used to assess the relation between the sediment's microstructure and the anisotropy of permeability. Indicators of anisotropy generally show modestly better alignment of grains in the horizontal direction. IntroductionEarthquakes and tsunamis are among the most unpredictable and destructive natural disasters, sometimes destroying life as well as buildings on a massive scale. Particularly destructive are those earthquakes occurring in subduction zones. Recent examples include the Sumatra earthquake and tsunami in 2004 and the earthquake and tsunami off the coast of Sendai (Tohoku) Japan in 2011.To better understand how and why earthquakes and tsunamis occur in subduction zones, it is useful to measure the mechanical and hydrological properties of sediments and sedimentary rocks retrieved by scientific ocean drilling. Among those many properties, permeability has an important influence on sediment consolidation and strength through its affect on pore fluid pressure (Moore and Vrolijk, 1992; Saffer and Bekins, 2006). By characterizing hydrological properties both within and adjacent to fault zones at various depths, we can examine how geologic structures and permeability might influence one another over a range of effective stress values, thereby improving the understanding of fault dynamics.Kinoshita, M., Tobin, H., Ashi, J., Kimura, G., Lallemant, S., Screaton, E.J., Curewitz, D., Masago, H., Moe, K. In this report, we present the results of constant-flow permeability tests that were completed at the University of Missouri on whole-round core specimens retrieved from the Nankai Trough accretionary prism offshore Japan (Fig. F1) (Fig. F1). The upper three samples come from lithologic Unit I (slope apron facies), whereas the lower three are from Unit II (upper accretionary prism). Bedding dips at the sampling depths are also shown on Figure F1. Unfortunately, the deepest sample could not be tested successfully because of severe fracturing.Previous laboratory tests of natural clay-rich sediment and shale tend to show large ranges in permeability values because of differences in the material'...

“…[12,13]). Anisotropy ratio in transport properties of clay-bearing formations which exhibit grain shape alignments may be pronounced [14][15][16][17][18][19]. Also, homogeneous grains appear to be hydraulically isotropic at their highest void ratio and their anisotropy ratio increases when the density increases [20].…”

“…Most of the observed variation in permeability of shale formations can be attributed to porosity variations [15,[21][22][23][24][25][26][27], grain size and pore size distributions [15,23,[25][26][27][28]. Furthermore, high anisotropy ratios observed in apparently homogeneous aquifers are caused to a lesser degree by orientation but caused mainly by micro-stratification [29].…”
