[BPT05-22] Cretaceous to Paleogene deep-water agglutinated foraminifers in the western North Pacific pelagic sediments
Keywords:deep-water agglutinated foraminifers, K-Pg boundary, pelagic sediments, western North Pacific Ocean
Recently, we constructed lithological description, including microfossils, for a pelagic sediment core of KR13-02 PC05 collected from the western North Pacific Ocean, and recognized a rapid decline of the density and diversity of DWAF across a spherule-rich layer. The spherules have a very similar appearance to those associated with the Chicxulub impact at the K-Pg boundary. We present a distribution of DWAF across the spherules-rich layer in the core and discuss its paleoceanographic implications.
