内容記述（抄録等）
Pollen flora of the latest Holocene at NU9007 core and Mudlump from southem part of Lake Nakaumi have been studied and correlated to pollen zones and subzones of Lake Shinji（Onishi et al．1990）．
In NU9007 core，Cryptomeria subzone，Cyclobalanopsis-Quercus subzone and Pinus subzone of Gramineae pollen zone are recognized and sedimentation rate is estimated to be 2.0 to 2.3 mm／year．
At Mudlump，Podocarpus subzone of Cyclobalanopsis-Castanopsis pollen zone and all subzones of Gramineae pollen zone are recognized and sedimentation rate is estimated to be 1.3 mm／year．
Sedimentation rate of NU8806（Watanabe et a1，1988）is also estimated to be 0.95 mm／year．
Pollen zoning of NB12 （Onishi，1977）has been reexamined and the subzones from
Apananthe-Celtis subzone of Fagus-Tsuga pollen zone to Pinus subzone of Gramineae pollen zone are recognized．Sedimentation rate is estimated to be 0.6 mm／year．
