New ages for volcanoes of the central and southern Emperor chain define large changes in volcanic migration rate with little associated change in the chain's trend, which suggests that the bend did not form by slowing of the Hawaiian hot spot. Initiation of the bend near Kimmei seamount about 50 million years ago (MA) was coincident with realignment of Pacific spreading centers and early magmatism in western Pacific arcs, consistent with formation of the bend by changed Pacific Plate motion.completedSolid-earth geophysicsabsolute ageAr/ArCenozoicdatesDeep Sea Drilling ProjectEast Pacific Ocean IslandsEmperor SeamountsEoceneHawaiihot spotsIPODLeg 55magmatismmovementNorth PacificNorthwest PacificOceaniaPacific OceanPacific PlatePaleogeneplate tectonicsPolynesiasea-floor spreadingseamountsspreading centerssubmarine volcanoesTertiaryUnited StatesvolcanoesWest Pacificurn:org.iodp:exp:55urnlargerWorkCitationcampaignEnglishgeoscientificInformation-179.0000171.000019.000045.0000Hawaiiapplication/pdfunknownSEDIS Publication Catalogueana.macario@awi.dehttp://sedis.iodp.org/pub-catalogue/informationpointOfContacthttp://www.sciencemag.org/content/313/5791/1281.full.pdfdownload
