A complex pattern of channeled turbidites has been mapped from detailed geological surveys of the eastern Central Pacific Basin between 157° and 172°W and including the Line Islands Ridge, the Central Basin Rise, the Kingman Basin, and the abyssal plain of the eastern Central Pacific Basin. The acoustic stratigraphy of about 5000 track miles of continuous reflection profiles has been analyzed for study of the depositional history of this region. The flanks of the Line Islands Ridge are blanketed by acoustically stratified, pelagic, nannofossil-foraminiferal oozes more than 1000 m thick. The Central Basin Rise has a similar lithology; sediment thicknesses vary from 100 to 1000 m. The Kingman Basin is filled with about 240 m of flat-lying, often ponded, calcareous turbidites interbedded with pelagic radiolarian ooze. The turbidites originate on the Central Basin Rise and the Line Islands Ridge. Adjacent to the Line Islands Ridge and the Central Basin Rise, in the abyssal plain of the eastern Central Pacific, channels filled with calcareous turbidites cut the siliceous pelagic sediments. The turbidites originate on the higher elevations of the Central Basin Rise and flow into the abyssal depths of the Central Basin through three graben-formed valleys, then are distributed by structurally controlled channels in the basement. Turbidite flows appear to have maintained these fixed channels and to have aggraded continuously since Eocene time.
