5 peat samples at Shimotashiro, Nakatashiro and Mt. Shibutsu (1810m) of the Oze district were studied palynologically. Pollen profiles of the first two stations show that a broad leaved forest tends to decrease in the upper layers, while conifers increase upward. This fact suggests that the upper layers correspond to Period R III and the lower to Period R II based on the zonation of Kamitashiro. That of Mt. Shibutsu shows a conifer stage throughout, corresponding to the upper layers of the above-mentioned profiles. The ash layers, in the pollen columns of Fig. 3,which we consider to be volcanic ash falls, were correlated to each other on the basis of pollen sequence.
