Its basement consists of pyroclastic rocks and highly vesicular hydrous pyroclastic olivine-basalt that displays ocean floor tholeiitic affinities. The fore-arc basin was formed during mid-Oligocene and is the product of for-arc rifting. Its basement is formed of calc-alkaline and low-K tholeiitic basalts and andesites depleted in high field strength elementscompletedSolid-earth geophysicsandesitesbasaltsbasinsbimodal compositionboninitecalc-alkalic compositionCenozoicfore-arc basinsigneous rocksisland arcsIzu-Bonin ArcLeg 126lithostratigraphymid-ocean ridgesmiddle OligoceneNeogeneNorth PacificNorthwest PacificOcean Drilling Programocean floorsoceanizationOligocenePacific OceanPacific PlatePaleogenePhilippine Sea Plateplate tectonicsPliocenepyroclasticsrhyolitesriftingsubductionTertiarytholeiitic basaltvolcanic rocksWest Pacificurn:org.iodp:exp:126urnlargerWorkCitationcampaignFrenchgeoscientificInformation139.5039140.531730.545732.2359
