Faunal analysis of Neogene planktonic foraminifera from forearc sediments of the Japan Trench, ODP Site 1151, Leg 186
Abstract The present paper describes the general outline of Neogene paleoceanographic changes in the northwestern Pacific by means of planktonic foraminiferal assemblages. Planktonic foraminiferal fossils occur commonly in the upper Miocene to lower Pleistocene sediments of Hole 1151A, Ocean Drillin...
