Abstract
The results of pollen analyses of HB1（Onishi，1980）are reexamined．
As there are some pollen grains of Carya，Liquidambar and Keteleeria，the lower parts of this core（33.8-34.6 meters in depth）may belong to the Miocene． As there are Lagerstroemia pollen grains，the middle parts（21.0-32.7 meters in depth）are correlated with the upper Pleistocene Yumigahama Formation（Onishi，1977）． The upper parts of the core（0.0−20.2 meters in depth）may be correlated with the Holocene Nakaumi Formation．The lower half of this formation is correlated with the Ulmus-Zelkova subzone of Pinus-Abies pollen zone to the Cyclobalanopsis-Quercus subzone of Gramineae pollen zone．Sedimentation rate of this part is estimated to be 1.68mm／y．The upper half is correlated with the Pinus subzone of Gramineae pollen zone． |
