The purpose of this study was to document the magnetic fabrics formed in a tensional environment. Faults and joints (healed fractures) were found in the lower portion of recovered core. Analysis of these structures suggests an east-west tensional direction. The general shape of the magnetic fabric ellipsoid is fairly oblate. Bedding planes dip to the east in Hole 1151, and the magnetic fabric is completely controlled by the bedding plane. The magnetic fabric in the interval highly affected by fracturing, however, shows higher anisotropy. Magnetic foliations, which have been reorientated using paleomagnetic north, incline eastward and westward.completedStratigraphyStructural geologyanhysteretic remanent magnetizationanisotropybeddingCenozoicdeformationfaultsfine-grained materialsfoliationfracturesJapan TrenchjointsLeg 186magnetic propertiesmagnetic susceptibilitymagnetizationmarine sedimentsNeogeneNorth PacificNorthwest PacificOcean Drilling ProgramODP Site 1151Pacific Oceanpaleomagnetismplanar bedding structuresremanent magnetizationsedimentary structuressedimentsstructural analysisstyleTertiaryWest Pacificurn:org.iodp:exp:186urnlargerWorkCitationcampaignurn:org.iodp:exp:186:site:1151urnlargerWorkCitationstudyurn:org.iodp:exp:186urnlargerWorkCitationcampaignEnglishgeoscientificInformation143.2000143.200038.450038.4500Available only on CD-ROM in PDF format and on the Web in PDF or HTMLapplication/pdfunknownSEDIS Publication Catalogueana.macario@awi.dehttp://sedis.iodp.org/pub-catalogue/informationpointOfContacthttp://www-odp.tamu.edu/publications/186_SR/VOLUME/CHAPTERS/113.PDFdownload
