During Ocean Drilling Program (ODP) Leg 198 to Shatsky Rise, a total of approximately 768 m of late Miocene-Holocene sediments was recovered from six sites. Sites 1207 and 1208 were drilled on the Northern and Central Highs, respectively, and yielded expanded late Miocene-Holocene sequences. Sites 1209, 1210, 1211, and 1212 were drilled on the Southern High and yielded shorter sequences of similar age. Clearly interpretable magnetic stratigraphies were obtained from all sites using the shipboard passthrough magnetometer. These results were augmented using discrete sample cubes (7 cm (super 3) ) collected shipboard and measured postcruise. Miocene age sediments are separated by a hiatus from Oligocene, Eocene, and Cretaceous age sediments beneath. An astrochronological age model was developed for the six sites based on cycles observed in reflectance data, measured shipboard. This age model is in good agreement with published astrochronological polarity chron ages in the 1- to 6-Ma interval.completedStratigraphyalternating field demagnetizationastrochronologyCenozoicdemagnetizationHoloceneLeg 198magnetizationmagnetostratigraphymarine sedimentsMiocenenatural remanent magnetizationNeogeneNorth PacificNorthwest PacificOcean Drilling ProgramPacific OceanpaleomagnetismPlioceneQuaternaryremanent magnetizationsedimentsShatsky RiseTertiaryupper MioceneWest Pacificurn:org.iodp:exp:198urnlargerWorkCitationcampaignEnglishgeoscientificInformation157.1500162.460031.340037.4800Available only on CD-ROM in PDF format and on the Web in PDF or HTML; includes appendixapplication/pdfunknownSEDIS Publication Catalogue
