Comparative Study of Miocene Fission-Track Chronology and Magneto-Biochronology
Fission-track ages of zircon crystals from 15 Miocene tuff layers in central and northeast Honshu, Japan have been determined. Ten of the sample horizons are controlled by biostratigraphic data of either calcareous nannoplankton or planktonic foraminifera, or both. A comparison between the fission-t...

Summary: | Fission-track ages of zircon crystals from 15 Miocene tuff layers in central and northeast Honshu, Japan have been determined. 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. |
