Recovery of basement rock provided an unprecedented opportunity to address the origin and evolution of this enigmatic appendage of the Aleutian arc massif. Contrasting hypotheses have been proposed for the formation of the arc massif of Bowers Ridge, either in the Cretaceous North Pacific Ocean exotic to the Bering Sea or within the Bering Sea during the Eocene formation of the Aleutian arc. The volcanic sequence recovered from Site U1342 was divided into six major lithologic units: Unit I, vesiculated andesitic lava flow; Unit II, interbedded volcanic sandstone and polymict volcanic conglomerate; Unit III, monomict volcanic conglomerate; Unit IV, interbedded volcanic sandstone and polymict volcanic conglomerate; Unit V, monomict volcanic conglomerate; and Unit VI, polymict volcanic conglomerate. Units III and IV represent hydroclastic volcaniclastic deposits, whereas Units II, IV, and VI are epiclastic volcaniclastic strata.completedStratigraphyandesitic compositionbasementBering SeaboreholesBowers RidgeCenozoicclastic rocksconglomeratecoresCretaceouscrustdescriptiondrillingEoceneExpedition 323igneous rocksIntegrated Ocean Drilling ProgramIODP Site U1342lavalithostratigraphymarine drillingMesozoicNorth PacificNorthwest Pacificoceanic crustPacific OceanPaleogenesandstonesedimentary rocksTertiaryvolcanic rocksvolcaniclasticsWest PacificEnglishgeoscientificInformation176.5504176.550454.494254.4942application/pdfunknownSEDIS Publication Catalogue
