Ten of the sample horizons are controlled by biostratigraphic data of either calcareous nannoplankton or planktonic foraminifera, or both. A comparison between the fission-track ages and the magneto-biostratigraphic constraints shows that the Anomaly 5-Chron 11 correlation is better than the Anomaly 5-Chron 9., 紀要類(bulletin), 944652 bytes}, pages = {93--106}, title = {Comparative Study of Miocene Fission-Track Chronology and Magneto-Biochronology}, volume = {58}, year = {1987} }
