Resumo |
Pollen floras were obtained from Miocene sediments recovered at four sites drilled during Ocean Drilling Program Leg 127. The local pollen floras of each site were correlated to the standard pollen zones of northeast Japan by using the concept of the essential members for each pollen zone. At Site 797, the complete floral range was obtained for recognition of the NP2 zone and the pollen components of the NP1 zone were also clarified continuously. The ages of the boundaries between pollen zones NP4/NP3, NP3/NP2, and NP2/NP1 are estimated to be about 7 Ma, 13 Ma, and 17-18.5 Ma, respectively. Even in the same pollen zone, the ratios of major pollen taxa vary with the location. This variation is expressed on maps representing two different times during the Miocene. |
