Overall, results indicate that permeability decreases with effective confining pressure up to 1.5 MPa; however, measurements at low effective pressure are too dispersed to yield a precise general relationship between permeability and pressure. When the effective pressure is increased from 1.5 to 2.5 MPa, permeability is roughly constant ( approximately 1-4 x 10-19 m (super 2) ). Samples deformed in the triaxial cell developed slickenlined fractures, and permeability measurements were performed before and after failure. A permeability increase is observed when the sample fails under low effective confining pressure (0.2 MPa), but not under effective pressure corresponding to the overburden stress. Under isotropic stress conditions, permeability decrease related to fracture closure occurs at a relatively high effective pressure of approximately 1.5 MPa. Coefficients of friction on the fractures formed in the triaxial cell are approximately 0.4.completedStructural geologycompressibilityconfining pressuredecollementfailuresfracturesfrictionLeg 190marine sedimentsmathematical modelsmeasurementmechanical propertiesNankai TroughNorth PacificNorthwest PacificOcean Drilling ProgramPacific Oceanpermeabilityrock mechanicssedimentary rockssedimentsslickenlinessoil mechanicsstructural analysistriaxial testsWest Pacificurn:org.iodp:exp:190urnlargerWorkCitationcampaignEnglishgeoscientificInformation134.0000135.150031.300032.4500Data report; available only on CD-ROM in PDF format and on the Web in PDF or HTMLapplication/pdfunknownSEDIS Publication Catalogue
