Palynological studies of the Cenozoic formations. (I)

Abstract

A clay bed including plant remains, situated in the suburbs of Kochi city was studied Palynologically. As the results of pollenanalytical studies, this bed shows a dominance of conifer forest throughout. While the deciduous broad-leaved trees are of less important and tends to decrease upward. The floral composition shown in this bed is similar to that of the present community at the height of about 800-1000 m in this district. From this fact it may be inferred that this bed was deposited in cooler and wetter climate. The age of deposition seems to be younger than that of Pliocene beds already published by Nakamura. (1951,1952) But more detailed correlation of this bed still remains for the future when many more analytical results have been obtained.
